The purpose of this book is to teach you convention and guideline applications as they pertain to AMA guidelines for coding applications. The purpose of CPT coding is to provide a means to report services to the patient. CPT codes often serve as a time use chart to track patient encounters or services. The patient’s medical record is the source for procedure codes that comply with regulations.

The care provided to a patient is documented in his or her medical record in terms of the services rendered. This documentation is a legal record of both the diagnoses and the procedures for a patient. The medical office documents every meeting with a patient by documenting the patient’s name, the encounter date and reason, the physician’s examination results, tests that were ordered, the diagnosis, the plan of care or notes on treatments that were performed, and the instructions given to the patient.

It is important for the coder to remember that using a CPT code does not guarantee that the provider will receive payment from the insurance company. It is often said, “If it is not documented, it did not happen,” meaning that Medicare and commercial carriers examine the medical necessity of services before payment. Therefore, if the physician performed a service, it must be documented in the medical record. If a carrier doubts that there is adequate medical necessity, it may conduct an audit of the documentation. In such a review, the carrier examines the medical record to ensure that the diagnosis and procedure codes are correctly linked and that services were provided at the correct level. If the service is not documented, the carrier will deny payment for the service even if a correct CPT code is used.

Training and Advancement

When you begin your career in the medical community, you will find that reimbursement and coding applications might be influenced by such factors as the following:


Many coders, after gaining basic experience on the job, seek certification as a coder. Certification is granted after the coder passes a national test of coding knowledge, and it increases the coder’s value to the practice. Two organizations offer coding certification.

The American Academy of Professional Coders grants the following certifications:

Understanding CPT

CPT was established in 1966 by the AMA to serve as a uniform language describing the services and procedures performed by physicians and other health care professionals. CPT serves as a guide to accurate reporting of medical, surgical, or diagnostic services rendered to a patient. It consists of five-digit numerical codes with descriptive explanations. CPT serves as a dependable, nationally accepted communication tool used by physicians, insurance companies, and patients. CPT is the HIPAA standard code set for reporting procedures.

CPT is updated and published every November to meet the constantly changing demands of the medical industry. As new codes are added, the older, obsolete codes are revised or deleted from the manual. Several factors must be considered before determining if a code should or should not be included in the updated edition of the CPT manual. Two key factors are as follows:

Note that the inclusion or exclusion of a code or description from CPT does not necessarily affect reimbursement for the procedure. Reimbursement policies are determined by individual third-party payers based on contract agreements and special clauses.

Code descriptions may be changed or added to CPT when a physician writes to the AMA asking that a new code be entered into the manual or an older code be expanded based on new methods and terminology. The inclusion or deletion of a code is a lengthy process involving the cooperation of the AMA, physicians, and medical societies.

The CPT manual contains six categories that are listed in numerical order, with the exception of the Evaluation and Management (E&M) codes. Because all practices use these E&M codes, the AMA has placed them in the front of the book for easy access.

What is a CPT Code?

A CPT code is a five-digit numerical code used to describe the professional services of a physician or other caregiver. Professional services may include medical, surgical, radiology, pathology or laboratory, anesthesiology, or evaluation and management services.

CPT codes are used by the following:

Information contained in the introduction explains the intent of the coding system while providing insight into the formats and terminologies used. Additional definitions are provided for CPT update requests, guidelines, modifier applications, and unlisted services or procedures.

CPT Code Components

Correct Use

The CPT coding system is a means of communicating to third-party payers exactly what the physician did to or for a patient. Correct use of the codes will help the practice receive, in a timely manner, the full reimbursement allowed for work performed by the physician.

Category I Codes

E&M (99201 to 99499)

E&M codes are listed first in the manual, as a matter of convenience, because they are the codes most commonly used by all medical practices. These codes are based on levels of service or treatment and the location in which the service was provided. A few examples of applications for E&M codes are office visits, hospital visits, and consultations.

Category II Codes

Codes in this section are supplemental tracking codes that can be used for measuring performance. The purpose of these codes is to reduce the need for record abstraction and chart review, thereby minimizing the administrative burden on health care providers and professionals. These codes facilitate data collection about the quality of care by coding certain measures that have been agreed upon as contributions to good patient care.

The use of these codes is optional. The codes are not required for correct coding, and they may not be used as a substitute for Category I codes. Note that because these codes describe components that are typically included in an E&M service or test results that are part of a laboratory procedure, there is no reimbursement value associated with them.

Category III Codes

Because of advances in technology and procedure development, the AMA has created another code series, the Category III codes. These codes are listed in the back of the CPT manual before Appendix A. These codes are temporary codes used for emerging technology, services, and procedures. Category III codes were established to more accurately capture information lacking in established codes and to eliminate overuse of the unlisted codes.

Unlike Category I codes, which are revised only once a year, Category II and III codes are updated semiannually in January and July. Updates can be obtained via the AMA/CPT web site (

In the following exercise, you will become familiar with the various sections of CPT. With time and experience, the coder is able to identify a particular code section by the first two digits of the procedure code.

CPT Coding and Medicare

Medicare did not adopt CPT coding until 1986. In 1986, CMS (formerly HCFA) developed a multilevel coding system to describe services and procedures. CMS named this coding system the Healthcare Common Procedure Coding System, more commonly referred to as HCPCS (sometimes pronounced “hick pix”).

Level II

This section, referred to as National Use Codes, contains codes created by Medicare as a supplement to the CPT manual. This publication lists more than 2000 codes for reporting supplies, services, or procedures that are not contained in the CPT manual developed by the AMA.

Level II codes differ from CPT in that they are alphanumeric codes. These codes begin with letters of the alphabet (A to V) followed by four numbers (e.g., A0001). Level II codes are generally accepted for reporting services nationwide because they were designed with set descriptions and guidelines for use.

Because level II HCPCS is a national coding set for Medicare carriers, copies may be purchased from the same companies that sell ICD-9-CM and CPT coding manuals. Unlike the CPT manuals, HCPCS level II codes are updated throughout the year. The updated or revised codes are published in the Medicare newsletters for your state and are available on the Internet.

CPT Format

It is important to understand how to use CPT correctly. The introduction to CPT provides instructions for using the manual. The introduction explains the format, the definitions of levels of service, and the symbols used; it also provides general instructions about using the manual. Each section also includes explanations pertinent to a particular chapter or subchapter that should be read before coding from that section.

Indented Format

CPT codes and definitions have been developed as stand-alone descriptions. However, to save space, CPT uses semicolons and indented text to abbreviate some procedure definitions.

A procedure description containing a semicolon (;) is divided into two parts:

Codes that immediately follow the code with the semicolon share the common language portion of the definition. The code shares the common portion of the definition. The codes immediately following are indented so you can easily see that they count as the wording to the right of the semicolon.

Coders unfamiliar with this format could double-bill the service by listing the base code and the indented code. Had the documentation stated “Fine-needle aspiration; with imaging guidance,” you would have listed CPT code 10022 on the claim form.

CPT Symbols

Symbol Function
image A circle or dot identifies a new code.
image A triangle identifies a revised code.
▶ ◀ Highlights new and revised text other than the procedure descriptors for ease in comparing the older data with the new or updated information.
+ Indicates an add-on code (e.g., +15787 . . . Abrasion; each additional four lesions or less).
image Used to identify codes exempt from modifier -51 (e.g., image20660, Application of cranial tongs, caliper, or stereotactic frame, including removal [separate procedure]).
; A semicolon is used to save space (e.g., 20670, Removal of implant; superficial [e.g., buried wire, pin, or rod] [separate procedure]).
image Bull’s-eye: This bull’s-eye symbol was added to indicate those procedures in which the provision of moderate sedation services is considered to be inherent and, therefore, not separately reported by the same physician performing the primary service.
image Lightning bolt: This convention was added to highlight products that are awaiting U.S. Food and Drug Administration (FDA) approval (e.g., 90661, Influenza virus vaccine, derived from cell cultures).
image Number sign is used to identify codes listed out of numerical sequence. See Appendix N.


Add-On Procedures (+)

Add-on codes are for procedures that are always performed during the same operative session as another surgery and are never performed separately. These codes are inherently secondary codes. The CPT manual highlights these codes by listing a plus (+) sign before the code and adding the phrase “each additional” or “list separately in addition to primary procedure.”

Unlisted Procedure Codes

Within each section and subsection, codes are provided to use when a description or code does not completely or accurately describe the service or procedure provided by the physician. These codes are unlisted procedures codes. They are easy to identify because they are listed as the last code in each section and usually end with the digits “99” or “9.” A complete list of unlisted procedure codes for each of the major six categories is provided in the notes or guidelines at the beginning of each category.

Coders must exercise particular care when using these codes, because reimbursement may be lower than anticipated. To provide a third-party payer with sufficient information to determine reimbursement, operative notes or any other supporting documentation should accompany these codes.

The AMA has listed procedures in alphabetical order at the back of the CPT manual. To find a code quickly, you should refer to this index.

The index offers the following four primary classes of main entries or ways to look up a code:

For each entry, a specific code or a range of codes may be provided to start the search for the exact code. To locate a code in the index, the coder should do the following:

The following page contains a short coding exercise to illustrate the various aspects involved in using the index. Refer to the index to locate the correct code.


The AMA developed modifiers to be used with codes to explain various aspects of coding. Modifiers help clarify codes and may maximize reimbursement. A complete list of CPT modifiers is found in Appendix A of the CPT manual.

In the HCPCS code list, Medicare has also developed level II modifiers to be used in addition to the CPT modifiers. The national modifier codes are AA thru ZZ. Two or more modifiers may be used with one code to give the most accurate description possible for that service. The modifier that has the greatest impact on reimbursement should be listed immediately after the CPT code.

Functions of a Modifier

The primary functions of modifiers are as follows:

CPT modifiers are reported with a two-digit numerical code added to the five-digit CPT code (e.g., 99201-57).

HCPCS level II modifiers are two-character alphabetical and/or alphanumeric codes added to the five-digit CPT code (e.g., 78814-TC).

All of the modifiers are listed with examples of correct coding applications.

Unusual Procedural Services
When the service provided is greater than the time or service usually required for the procedure.
Example:A surgical procedure that usually takes 1 hour took 3 hours. A report or summary should accompany the claim to explain the reason for the increase in charges.
Correct Coding: 58180-22 (Supracervical abdominal hysterectomy)

Unusual Anesthesia
Occasionally, a procedure that usually requires either no anesthesia or local anesthesia must be done under general anesthesia because of unusual circumstances. This circumstance is reported by adding modifier -23 to the procedure code of the basic service.
Example:During a sigmoidoscopic procedure, the patient required general anesthesia.
Correct Coding: 45330 Sigmoidoscopy, flexible
45330-23 General anesthesia applied

Unrelated Evaluation and Management Service by the Same Physician during a Postoperative Period
Use this modifier when the physician needs to indicate that an E&M service was performed during a postoperative period for a reason (or reasons) unrelated to the original procedure.
Example:A patient had gallbladder surgery but came to the office because of a cold 3 weeks following the procedure (same physician). By using this modifier, the coder alerts the carrier that the office visit was not related to the surgical procedure. The physician will then be paid for the visit pertaining to the cold.
Correct Coding: 99213-24 (Established patient office visit)

Significant, Separately Identifiable E&M Service by the Same Physician on the Day of a Procedure
This modifier indicates that on the day a procedure or other service was performed, the patient’s condition required a significant, separately identifiable E&M service above and beyond the usual preoperative and postoperative care associated with the procedure that was performed.
Example:A patient was seen for a sore throat and the removal of a wart. Both services (the office visit and the procedure) should be coded, because the reason for the office visit (sore throat) was unrelated to the reason for the surgery.
Correct Coding: 17110 Wart removal
99213-25 Office visit

Professional Component
Certain procedures are a combination of a physician component and a technical component. To report only the physician component, add this modifier to the CPT code number.
Example:The patient has had a chest x-ray, and the physician is only interpreting the film.
Correct Coding: 71010 Radiology examination, chest, single
71010-26 Interpretation only

Mandated Services
This modifier applies to services related to mandated treatments or testing (e.g., third-party payer, governmental, legislative, or regulatory requirement).
Example:Mandated service
Correct Coding: 99243-32 Outpatient consultation, mandated

Anesthesia by Surgeon
Use this modifier to code for the services of regional or general anesthesia when this service is provided by the surgeon. Do not use it to code local anesthesia.
Example:The surgeon who drained the patient’s cyst also administered a regional anesthetic.
Correct Coding: 40801-47 Drainage of abscess, cyst, hematoma, vestibule of mouth; with application of anesthesia by the surgeon

Bilateral Procedure
When the same procedure is performed on both sides of the body, use this modifier to indicate that service. The modifier is appended to the second procedure.
Example:The patient had two hernias, one in the right groin and one in the left groin that were repaired at the same operative session.
Correct Coding: 49520 Repair recurrent inguinal hernia, right side
49520-50 Repair recurrent inguinal hernia, left side

Multiple Procedures
When multiple procedures other than E&M services are performed on the same day or during the same operative session by the same provider. The services are reported as follows:
Example:The surgeon removed the patient’s uterus and also cut an opening into the bladder to drain it.
Correct Coding: Primary procedure: 58150 Supracervical abdominal hysterectomy
Secondary procedure: 51040-51 Cystostomy with drainage

Reduced Services
Under certain circumstances, a service or procedure is partially completed. This modifier alerts the carrier that a reason exists for a lower than usual charge. The reduced services modifier will protect the charge data for the practice.
Example:93923, Noninvasive physiological studies of upper or lower extremity arteries, multiple levels or with provocative functional maneuvers, complete bilateral study (e.g., segmental blood). The study was performed on a patient with a history of amputation of the extremity.
Correct Coding: 93923-52 Noninvasive physiological studies of upper or lower extremity arteries

Discontinued Procedure
The physician may elect to terminate a procedure due to extenuating circumstances or because it threatens the well-being of the patient. Note: This modifier is not used to report the elective cancellation of a procedure before the patient’s anesthesia induction and/or surgical preparation in the operating suite.
Example:The physician began a colonoscopy but had to discontinue the procedure because the patient had not been properly prepped.
Correct Coding: 45378-53 Colonoscopy, discontinued

Surgical Care Only
This modifier indicates that one physician performed a surgical procedure and another physician provided preoperative and/or postoperative management.
Example:The physician performed only the laminectomy.
Correct Coding: 63250-54 Laminectomy, surgical procedure only

Postoperative Management Only
This modifier indicates that a physician other than the surgeon provided the postoperative care.
Example:A physician other than the surgeon provided the postoperative management of the laminectomy.
Correct Coding: 63250-55 Laminectomy, postoperative management

Preoperative Management Only
This modifier indicates that a physician other than the surgeon provided the preoperative evaluation of the patient.
Example:A physician, other than the surgeon, performed the preoperative evaluation before the patient was admitted for a laminectomy.
Correct Coding: 63250-56 Laminectomy, preoperative management

Decision for Surgery
Use this modifier for an E&M service that results in the initial decision to perform surgery. It applies only to major procedures (i.e., those with a 90-day global period) when surgery is performed within 24 hours of the decision for the surgery.
Example:During the encounter with the surgeon, the decision was made to perform surgery the next day.
Correct Coding: 99203-57 Initial office visit with decision for surgery made at the time of the visit

Staged or Related Procedure or Service by the Same Physician during the Postoperative Period
This modifier is used when the physician needs to indicate that a procedure or service performed during the postoperative period was planned prospectively at the time of the original procedure (staged), was more extensive than the original procedure, or was performed for therapy following a diagnostic surgical procedure.Example:The patient had a breast biopsy. The results indicated a need for a partial mastectomy. The service was scheduled within the 10-day global period of the biopsy.
Correct Coding: 19160-58 Mastectomy, partial

Distinct Procedural Service
This modifier indicates that a procedure or service was distinct or independent from other services performed on the same day. It is used to identify procedures or services that are not normally reported together but are appropriate under the circumstances. This may represent a different patient encounter, different site or organ system, separate lesion, or separate injury not ordinarily encountered or performed on the same day by the same physician.
Example:Removal of a lesion from the arm and another from the back.
Correct Coding: 11601 Excision, malignant lesion (first lesion)
11601-59 Excision, malignant lesion (second lesion)

Two Surgeons
Under certain circumstances, two surgeons (usually with different skills) may be required to manage a surgical procedure.
Example:A laminectomy was performed by a neurosurgeon and an orthopedic surgeon. Each bills the same CPT code with modifier -62.
Correct Coding: 63250-62 Laminectomy, two surgeons

Procedure Performed on an Infant Weighing Less Than 4 kg
In some cases, the small size of a neonate or infant significantly increases the complexity and physician work components required for a procedure. This modifier is used only for procedures on patients in this circumstance.
Example:The patient is a 3-kg infant who requires an enterectomy, resection of small intestine.
Correct Coding: 44120-63 Enterectomy, resection of small intestine; single resection and anastomosis

Surgical Team
Use this modifier when highly complex procedures (i.e., those requiring the concomitant services of several physicians, often of different specialties, plus other highly skilled, specially trained personnel and various types of complex equipment) are carried out under the “surgical team” concept.
Example:A heart transplantation required the skills of a highly trained cardiovascular team.
Correct Coding: 33945-66 Heart transplant, with or without recipient cardiectomy

Repeat Procedure by Same Physician
Use this modifier when a physician needs to indicate that a procedure or service was repeated subsequent to the original service on the same day.
Example:The patient had an ECG (93000) in the morning with a repeat ECG in the afternoon.
Correct Coding: 93000-76 ECG, repeat procedure

Repeat Procedure by Another Physician
This modifier indicates that a procedure had been performed by another physician on the same day and was repeated by a different physician.
Example:The patient had an ECG (93000) at the primary care physician’s office and was sent to a cardiologist who repeated the ECG on the same day.
Correct Coding: 93000-77 ECG, repeat procedure

Return to the Operating Room for a Related Procedure
This modifier indicates that another procedure, related to the first procedure, was performed during the initial procedure’s postoperative period and required a return to the operating room.
Example:The patient had abdominal surgery. Three days after surgery an infection occurs in the wound site, requiring the patient to return to the operating room for debridement of the wound site.
Correct Coding: 11000-78 Debridement of necrotic tissue, related procedure

Unrelated Procedure or Service in a Postoperative Period
When a patient is seen by the same physician for an unrelated problem or condition during the postoperative period, use this modifier.
Example:A patient has a Maze procedure for the treatment of atrial fibrillation (33253) and goes home. The wound site is healing well. Two weeks later, the patient is seen by the same physician for pericardiotomy for removal of a foreign body (33020). Because the second procedure is within the global period for the original surgery, attach modifier -79 to the second procedure.
Correct Coding: 33020-79 Pericardiotomy

Surgical Assistant
This modifier identifies the services of another physician who acts as a second pair of hands for a surgical procedure.
Example:A patient undergoes intestinal fistula closure (44640), requiring the assistance of another physician to complete. The primary surgeon would report the service as 44640. To report the services of the assistant, add modifier -80 to the same code.
Correct Coding: 44640-80 Closure of intestinal fistula (Surgical assisting coding only)

Minimum Assistant Surgeon
Use this modifier for a procedure that does not normally require a surgical assistant but because of extenuating circumstances requires the services of another physician for a short time.Note: Many commercial insurance companies allow this modifier to be used when assistance is provided by personnel other than an MD or DO. For Medicare carriers, you must use modifier -AS to report services provided by an assistant who is not an MD or DO.
Example:A patient treated for gingivitis requiring a gingivectomy (41820, excision gingiva, each quadrant) required the assistance of another physician for a short period of time. Note: This modifier may also be used to report surgical assistance of a nurse practitioner or physician assistant based on insurance company policies.
Correct Coding: 41820-81 Gingivectomy, excision gingiva, each quadrant

Assistant Surgeon
Use this modifier when a qualified resident surgeon is not available. This modifier is typically reserved for teaching hospitals and teaching physician services.
Example:A teaching physician required assistance to close an intestinal fistula. At the time of the procedure, a resident was not available to provide assistance. Another teaching physician had to assist with the procedure.
Correct Coding: 44640-82 Closure of intestinal fistula

Reference (Outside) Laboratory
This modifier is used when laboratory procedures are performed by a party other than the treating or reporting physician. Use this modifier with only the 80000 code series.
Example:A patient with Conn’s disease is scheduled for aldosterone studies in the morning and in the afternoon to compare the results of electrolyte excretion by the kidneys.
Correct Coding: 82088-90 Aldosterone

Repeat Clinical Diagnostic Laboratory Test
Use this modifier to indicate a repeat of the same laboratory test on the same day to obtain subsequent (multiple) test results.
Note: This modifier may not be used when tests are performed to confirm initial results; when specimen testing problems or equipment failure occur; or for any other reason when a normal, one-time, reportable is all that is required. This modifier may not be used when other code(s) describe a series of test results (e.g., glucose tolerance testing, evocative/suppression testing).
Correct Coding: 82088 Aldosterone
82088-91 Aldosterone

Alternate Laboratory Platform Testing
Use this modifier when laboratory testing is performed using a kit or transportable instrument.
Correct Coding: 86701
HIV testing
HIV testing
