Summary & Overview
CPT 0116U: Snapshot Oral Fluid Compliance Test
CPT code 0116U identifies a proprietary laboratory test — the Snapshot™ Oral Fluid Compliance assay from Ethos Laboratories — that combines oral fluid drug screening with an algorithmic analysis to assess medication compliance and potential drug–drug interaction risk. As a PLA code, it is unique to a single manufacturer and represents a growing category of lab services that pair biochemical testing with proprietary clinical algorithms. Nationally, such tests are notable for their implications on clinical decision support, laboratory reporting, and payer coverage policies.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical purpose and service model, common payer coverage considerations, and coding context. The publication outlines benchmarks and policy-relevant issues for PLA codes, explains typical sites of service and how the algorithmic component factors into clinical interpretation, and summarizes available payer approaches and potential prior authorization or documentation expectations.
This summary is intended for clinicians, billing staff, laboratory managers, and policy analysts looking for a national-level briefing on CPT code 0116U, its clinical role, and the payer landscape surrounding proprietary laboratory analyses.
Billing Code Overview
CPT code 0116U is a Proprietary Laboratory Analyses (PLA) code for the Snapshot™ Oral Fluid Compliance test from Ethos Laboratories. The service combines an oral fluid drug test with an algorithmic analysis that uses patient data and laboratory results to report patient medication compliance and risk of drug–to–drug interactions.

Service type: Laboratory test with algorithmic clinical interpretation
-
Typical site of service: Clinical laboratory or outpatient collection site (oral fluid specimen collection and laboratory processing)
Clinical & Coding Specifications
Clinical Context
A 46-year-old patient receiving chronic opioid therapy for chronic low back pain presents for routine monitoring and medication management. The prescriber orders the Snapshot™ Oral Fluid Compliance test from Ethos Laboratories (0116U) to confirm recent use of prescribed opioids, detect non-prescribed or illicit substances, and assess risk for drug–drug interactions using the laboratory result combined with the patient’s medication list and clinical data. An oral fluid specimen is collected at an outpatient clinic or external collection site; the specimen is sent to Ethos Laboratories. The lab performs targeted toxicology on the oral fluid and runs an algorithmic analysis incorporating the patient’s reported medications and test results to generate a compliance and interaction-risk report. Results are returned to the ordering clinician and integrated into the medication management visit to inform follow-up, such as adherence counseling, medication adjustments, or referral to addiction medicine if indicated.
