Official Description

Amines, vaginal fluid, qualitative

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

A CPT® Code 82120 refers to the qualitative analysis of amines in vaginal fluid, specifically aimed at detecting bacterial vaginosis. This procedure is essential for patients who present with symptoms such as vaginal discharge and an unpleasant odor. During the test, a sample of vaginal fluid is collected using a swab and then placed onto specialized test media designed for this analysis. The qualitative aspect of the test indicates that it determines the presence or absence of certain substances, rather than measuring their exact quantities. The test employs a rapid colorimetric method utilizing layered thin-film technology, which allows for a quick assessment of alkali volatilizable amines in the vaginal fluid. The results obtained from this test are crucial for the physician, as they are used alongside a clinical evaluation to either confirm or exclude bacterial vaginosis as the underlying cause of the patient's symptoms. This procedure plays a significant role in guiding appropriate treatment options for the patient.

1. Indications

The qualitative analysis of vaginal fluid amines, coded as CPT® 82120, is indicated for patients presenting with specific symptoms related to vaginal health. The primary indications for this procedure include:

  • Vaginal Discharge The presence of abnormal vaginal discharge that may suggest an underlying infection or condition.
  • Odor A noticeable and unpleasant odor associated with vaginal discharge, which may indicate bacterial vaginosis.

2. Procedure

The procedure for performing the qualitative analysis of vaginal fluid amines involves several key steps, which are outlined as follows:

  • Step 1: Sample Collection A healthcare provider collects a sample of vaginal fluid using a sterile swab. This step is crucial as it ensures that the sample is uncontaminated and suitable for testing.
  • Step 2: Placement on Test Media The collected vaginal fluid swab is then placed onto specialized test media designed for the qualitative analysis of amines. This media is formulated to facilitate the detection of specific substances present in the vaginal fluid.
  • Step 3: Rapid Colorimetric Testing A rapid colorimetric test is performed using layered thin-film technology. This innovative method allows for the quick detection of alkali volatilizable amines, which are indicative of bacterial vaginosis.
  • Step 4: Interpretation of Results The results of the test are evaluated to determine the presence or absence of amines in the vaginal fluid. These results are then used in conjunction with the physician's clinical evaluation to diagnose or rule out bacterial vaginosis.

3. Post-Procedure

After the qualitative analysis of vaginal fluid amines is completed, the patient may receive guidance based on the test results. If bacterial vaginosis is confirmed, appropriate treatment options will be discussed. The physician may also provide recommendations for follow-up care or additional testing if necessary. It is important for the patient to monitor any ongoing symptoms and report them to their healthcare provider to ensure effective management of their condition.

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.
