Summary & Overview
CPT 0330U: Bridge Women’s Health 27-Pathogen Vaginal NAAT
Headline: New PLA CPT code 0330U identifies a 27-pathogen NAAT for vaginal infections
Lead: CPT code 0330U designates the Bridge Women’s Health Infectious Disease Detection Test, a proprietary nucleic acid amplification test (NAAT) for detecting 27 vaginal pathogens from a vaginal swab. The code enables clear reporting for a single manufacturer’s assay and supports national tracking of molecular testing for common vaginal infections.
Why it matters: As molecular diagnostics expand, PLA codes like 0330U provide specificity for payer adjudication, utilization monitoring, and clinical decision support. Accurate reporting affects coverage determination, claims processing, and surveillance of common reproductive tract infections.
Payers covered: This analysis addresses major national payers including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
What readers will learn: The publication explains the clinical scope of CPT code 0330U, typical service context (laboratory NAAT on vaginal swab specimens), and the significance of PLA designation. It summarizes expected topics readers can use: code definition and clinical context, payer coverage considerations, common modifiers used in lab billing, and implications for billing workflows and test reporting. Where input lacks details, the publication notes missing specifics as “Data not available in the input.”
Billing Code Overview
CPT code 0330U is a Proprietary Laboratory Analyses (PLA) code for the Bridge Women’s Health Infectious Disease Detection Test produced by Bridge Diagnostics. This nucleic acid amplification test (NAAT) evaluates a vaginal swab specimen for the presence or absence of 27 vaginal pathogens, including bacteria such as Gardnerella vaginalis, various Candida species (yeast), and Trichomonas vaginalis (TV).
Service type: Laboratory testing — molecular diagnostic NAAT
Typical site of service: Clinical laboratory or outpatient collection site where vaginal swab specimens are collected and submitted to the performing laboratory for analysis.
Clinical & Coding Specifications
Clinical Context
A reproductive-age female presents to an outpatient gynecology clinic with symptoms of vaginal discharge, odor, itching, or pelvic discomfort. The clinician performs a pelvic exam and collects a vaginal swab specimen for nucleic acid amplification testing (NAAT). The specimen is sent to Bridge Diagnostics for the Bridge Women’s Health Infectious Disease Detection Test reported with CPT code 0330U. Results identify the presence or absence of a panel of 27 vaginal pathogens (for example, Gardnerella vaginalis, Candida species, and Trichomonas vaginalis) to guide targeted antimicrobial or antifungal therapy and to inform partner management and counseling. Typical site of service is an outpatient clinic, physician office, urgent care center, or ambulatory specimen collection site where pelvic exams and swab collection are performed. The clinical workflow includes patient history and exam, specimen collection, laboratory requisition and shipment to the performing laboratory, result reporting into the electronic health record, and subsequent treatment planning or follow-up testing as indicated.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
00 | Regular, unmodified service | Use when no modifier applies and the test is billed normally by the performing laboratory. |
22 | Increased procedural services | Use when unusually high complexity in specimen processing or testing requires additional documentation and supports higher payment where allowed. |
26 | Professional component | Use if a separate reporting of the professional interpretive component is required (rare for PLA lab tests; most labs bill global). |
52 | Reduced services | Use when the lab performs a reduced portion of the full service and documentation supports reduced payment. |
53 | Discontinued procedure | Use when testing was started but discontinued for documented clinical reasons prior to completion. |
62 | Two surgeons | Not routinely used for laboratory tests but may be appended when two providers share responsibility for specimen collection in unusual surgical settings. |
78 | Unplanned return to OR | Not routinely applicable to this outpatient laboratory test; include only if a surgical reintervention relates to the specimen collection. |
80 | Assistant at surgery | Not typically applicable to this lab test; included for completeness where surgical specimen collection involved a surgical assistant. |
TC | Technical component | Use when billing only the laboratory technical component (equipment, technician) while another entity bills the professional component. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207Q00000X | Obstetrics & Gynecology | Gynecologists commonly collect vaginal swabs and order testing. |
363L00000X | Clinical Laboratory | Performing laboratory specialty responsible for running the PLA test and reporting results. |
2084P0800X | Family Medicine | Primary care and family practitioners frequently collect specimens and order testing for vaginal infections. |
174400000X | Infectious Disease | Infectious disease specialists may interpret complex or recurrent infection panels and guide management. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
N76.0 | Acute vaginitis | Common indication for vaginal NAAT panel when patients present with acute symptoms of vaginitis. |
N76.1 | Subacute and chronic vaginitis | Indication for testing in recurrent or persistent vaginal symptoms to identify causative pathogens. |
A59.0 | Trichomoniasis | Pathogen commonly detected by the panel; testing confirms presence of Trichomonas vaginalis. |
B37.3 | Candidiasis of vulva and vagina | Candida species are included in the panel; code relevant when yeast infection is suspected. |
N89.8 | Other specified noninflammatory disorders of vagina | Used when abnormal vaginal discharge or findings do not fit other specific codes and pathogen detection is needed. |
Z11.3 | Encounter for screening for infections with a predominantly sexual mode of transmission | Applied when the test is performed for screening asymptomatic individuals at risk for sexually transmitted infections. |
R82.3 | Abnormal findings on microbiological examination of vagina and vulva | Used when lab testing yields abnormal microbiologic results that need to be coded for billing and record-keeping. |
Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
|---|---|---|
87660 | Infectious agent detection by nucleic acid (DNA or RNA); Chlamydia trachomatis/Neisseria gonorrhoeae, amplified probe technique | May be ordered alongside or as alternative NAATs for common sexually transmitted infections when separate targeted testing for CT/GC is required. |
87661 | Infectious agent detection by nucleic acid (DNA or RNA); Trichomonas vaginalis, amplified probe technique | May be ordered in conjunction with the panel when a dedicated NAAT for Trichomonas confirmation is desired or when billing separate focused testing. |
