Official Description

Colposcopy of the vulva; with biopsy(s)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 56821 involves a colposcopy of the vulva, which is a diagnostic examination performed by a physician to closely inspect the vulvar tissue for any abnormalities. A colposcope, a specialized instrument resembling binoculars mounted on a stand with an integrated light source, is utilized during this procedure. This device magnifies the vulvar tissue, enabling the physician to observe any irregularities more clearly. The examination encompasses a thorough inspection of the entire vulva, typically conducted under two or three different levels of magnification to enhance the visualization of the tissue. To facilitate the identification of abnormal cells, acetic acid is applied to the vulva, which helps to highlight any atypical areas. Following this, various colored filters are employed to examine the blood vessels and detect any unusual patterns that may indicate pathology. Additionally, an iodine solution is applied to stain the glycogen present in the cells; normal cells will exhibit a dark-brown coloration, while areas that do not take up the stain are considered suspicious and are subsequently biopsied. This code is specifically used when one or more biopsies are performed during the colposcopy, distinguishing it from CPT® Code 56820, which is designated for colposcopy of the vulva without biopsy.

1. Indications

The colposcopy of the vulva with biopsy, as described by CPT® Code 56821, is indicated for the following conditions:

  • Abnormal Pap Smear Results - This procedure is often performed when a Pap test indicates the presence of atypical squamous cells or other abnormalities that require further investigation.
  • Visible Lesions - If there are visible lesions or abnormalities on the vulva that warrant closer examination, a colposcopy with biopsy may be indicated to assess the nature of these lesions.
  • Persistent Vulvar Symptoms - Symptoms such as itching, burning, or pain in the vulvar area that do not respond to standard treatments may lead to the need for a colposcopy to identify underlying issues.

2. Procedure

The procedure for a colposcopy of the vulva with biopsy involves several key steps:

  • Step 1: Preparation - The patient is positioned comfortably, and the physician prepares the colposcope, ensuring that the light source is functioning properly for optimal visualization.
  • Step 2: Initial Examination - The physician begins by placing the colposcope at the vulva, allowing for a comprehensive inspection of the vulvar tissue. This initial examination is conducted under low magnification to identify any obvious abnormalities.
  • Step 3: Application of Acetic Acid - Acetic acid is then applied to the vulva. This solution enhances the visibility of abnormal cells by causing them to appear whiter, thus making it easier for the physician to identify areas of concern.
  • Step 4: Use of Colored Filters - After the application of acetic acid, the physician utilizes different-colored filters to examine the blood vessels in the vulvar tissue. This step is crucial for detecting abnormal blood vessel patterns that may indicate pathology.
  • Step 5: Iodine Staining - The vulva is subsequently painted with an iodine solution, which stains glycogen in the cells. Normal cells will take on a dark-brown color, while areas that do not stain are noted for further evaluation.
  • Step 6: Biopsy of Abnormal Areas - Any areas that do not stain with iodine, as well as those previously identified with abnormal blood vessel patterns, are biopsied. This involves the removal of small tissue samples for histological examination to determine the presence of any pathological conditions.

3. Post-Procedure

After the colposcopy with biopsy, the patient may experience some mild discomfort or spotting. It is important for the physician to provide post-procedure care instructions, which may include recommendations for managing any discomfort and guidelines on activity restrictions. Patients are typically advised to avoid sexual intercourse, douching, or using tampons for a specified period following the procedure to allow for proper healing. Additionally, the physician may schedule a follow-up appointment to discuss biopsy results and any further necessary actions based on the findings.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
