Required Actions & Billing Notes

Documentation Required
Symptom documentation and initial diagnostic workup
For symptomatic patients, document a complete history and physical exam and perform vaginal pH testing, a potassium hydroxide (KOH) whiff test, and microscopy (wet mount) of vaginal discharge as the initial evaluation per guideline recommendations.

Prior Authorization
Use of multiplex NAATs limited to symptomatic patients
Multiplex NAAT assays are intended for use in symptomatic patients with signs consistent with vaginitis/vaginosis and are not intended for routine screening of asymptomatic patients, prognostic use, or as a test-of-cure. Prior authorization applies to these proprietary/multiplex NAAT codes when used outside intended symptomatic indications.
0330U
0505U
81513
81514
81515

Documentation Required
Retesting for Trichomonas
Retest patients for Trichomonas vaginalis within 3 months after treatment because of high recurrence rates (ACOG recommendation, Level B).
87660
87661

Billing Rule
Use of specific specimen swabs / lab requirements
Some commercial laboratory assays require a specified swab or specimen type; order the test with the laboratory-specified specimen (eg, clinician- or self-collected vaginal swab) to avoid processing or nonreportable result issues.
Order clinician- or patient-collected vaginal swab as required by the selected assay

Background & Evidence

This section compiles guideline recommendations from major organizations (ACOG, IDSA, SOGC, Australian guidelines, CDC and USPSTF) that support a standard initial evaluation of symptomatic vaginitis using history, physical exam, vaginal pH, KOH whiff test, and microscopy; and that recommend specific tests: Amsel or Nugent Gram stain for BV, microscopy/culture for VVC confirmation, and NAAT for trichomoniasis.

The background summarizes regulatory and test-specific information: multiple FDA-cleared multiplex NAATs (eg, BD MAX Vaginal Panel; Aptima BV and Aptima CV/TV) and several laboratory-developed multiplex assays exist. Evidence and guideline statements note that NAATs have higher sensitivity and negative predictive value than clinician assessment or many point-of-care tests and can identify mixed infections, but their diagnostic accuracy is established primarily for symptomatic women and may detect organisms of uncertain clinical relevance in asymptomatic persons.

Label	Value
ACOG Practice Bulletin Number 215
2020 (reaffirmed 2022) — Recommends Amsel criteria or Gram stain with Nugent scoring for BV; NAAT for trichomoniasis; microscopy or culture or commercial diagnostic test positive for Candida species to confirm VVC; notes advanced single‑swab multiplex PCR/DNA probe panels as a promising alternative to microscopy
IDSA guidance
Supports diagnostic confirmation prior to empiric antifungal therapy; describes FDA‑cleared multiplex vaginal NAATs (BD MAX, Aptima BV/CV/TV, Xpert/Cepheid) and notes multiplex NAATs have higher sensitivity and NPV than clinician assessment or POCTs and detect coinfections; multiplex tests intended for symptomatic patients and not for screening asymptomatic patients or test‑of‑cure
FDA approvals
BD MAX Vaginal Panel: Class III designation (approved 2016; modification 2019); Aptima BV Assay: FDA approved May 23, 2019; Aptima CV/TV and other Aptima assays FDA cleared in 2019; code descriptors and proprietary panel codes listed (e.g., 81513, 81514, 81515, 0330U, 0505U)
