Summary & Overview

CPT 0429U: Omnipathology Oropharyngeal HPV PCR Test

CPT code 0429U designates a Proprietary Laboratory Analyses (PLA) molecular test: the Omnipathology Oropharyngeal HPV PCR Test. The assay detects DNA from 14 high‑risk human papilloma virus (HPV) types in an oropharyngeal swab specimen and is reported only for the specific manufacturer’s test. Nationally, PLA codes like 0429U matter because they identify single‑source diagnostics with implications for coverage, pricing transparency, and laboratory reimbursement pathways.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise briefing on the clinical context of oropharyngeal HPV testing, the service setting for this molecular diagnostic, and what PLA designation means for coding and billing. The publication provides benchmarks and policy context relevant to proprietary molecular tests, outlines typical payer coverage considerations, and highlights operational factors for laboratories and clinicians handling oropharyngeal swab specimens. Data not available in the input for associated taxonomies, ICD-10 diagnoses, and related codes are noted where applicable.

Billing Code Overview

CPT code 0429U is a Proprietary Laboratory Analyses (PLA) code that applies exclusively to the Omnipathology Oropharyngeal HPV PCR Test from OmniPathology Solutions Medical Corporation. The test evaluates an oropharyngeal swab specimen for the presence of DNA associated with 14 high–risk human papilloma virus (HPV) types listed in the code. Service type: Molecular diagnostic assay for detection of high‑risk HPV DNA. Typical site of service: Clinical laboratory or reference laboratory processing oropharyngeal swab specimens.

Clinical & Coding Specifications

Clinical Context

A 46-year-old adult presents to an outpatient otolaryngology clinic with a several-week history of persistent sore throat, odynophagia and a unilateral tonsillar exophytic lesion on physical exam. The clinician obtains an oropharyngeal swab at the visit and orders the Omnipathology Oropharyngeal HPV PCR Test (0429U) to detect DNA from 14 high‑risk human papillomavirus types associated with oropharyngeal squamous cell carcinoma risk. The specimen is collected during the clinic visit and sent to the manufacturer‑specific laboratory. The typical workflow includes: specimen collection (oropharyngeal swab) at an outpatient clinic or ambulatory surgery center, laboratory accessioning and performance of the proprietary PCR assay at the OmniPathology Solutions Medical Corporation laboratory, electronic reporting of results to the ordering clinician, and incorporation of findings into the patient’s diagnostic and treatment plan (surveillance, referral to oncology or head and neck surgery, or further diagnostic biopsy). Typical site of service: outpatient clinic, ambulatory surgical center, or hospital outpatient department when oropharyngeal evaluation is performed.
