Summary & Overview
CPT 0011U: Cordant CORE™ Oral Fluid Drug Test with Algorithmic Steady‑State Comparison
CPT code 0011U is a Proprietary Laboratory Analyses (PLA) code that identifies Cordant CORE™ by Cordant Health Solutions, a laboratory-developed assay that tests oral fluid for drugs and applies an algorithmic analysis to estimate whether detected drug levels align with an estimated steady–state range. PLA codes are specific to a single manufacturer or laboratory test, making 0011U important for claims processing, coverage determinations, and lab billing consistency across payers. Nationally, algorithm-driven toxicology assays raise issues around clinical validity, coding specificity, and payer coverage policies.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find: an explanation of what the code represents and its clinical context; payer coverage considerations and where policy review may be required; benchmarking concepts relevant to proprietary lab tests; and operational details for billing and site-of-service expectations. The publication highlights how 0011U fits into laboratory service lines and the implications of PLA coding for utilization management, prior authorization workflows, and lab-to-payer communication.

Billing Code Overview
CPT code 0011U is a Proprietary Laboratory Analyses (PLA) code describing Cordant CORE™ by Cordant Health Solutions, a laboratory-developed drug test performed on an oral fluid specimen. The test combines laboratory measurement of drug(s) in oral fluid with an algorithmic analysis using patient data and the lab results to report a comparison of detected drug(s) to an estimated steady–state range.
Service type: Laboratory — Proprietary/Algorithmic Drug Test
Typical site of service: Clinical laboratory or reference lab
Clinical & Coding Specifications
Clinical Context
A patient enrolled in an outpatient pain management program presents for routine monitoring of prescribed opioid therapy. The clinician orders 0011U (Cordant CORE™) to assess steady‑state exposure to a prescribed opioid using an oral fluid specimen combined with an algorithmic analysis that incorporates the assay result plus patient medication information and dosing history. The workflow includes: collection of an oral fluid sample at the clinic or collection site, shipment to the performing laboratory, laboratory immunoassay and/or mass spectrometry confirmation as needed, algorithmic analysis comparing measured drug concentrations to estimated steady‑state ranges based on the patient’s reported regimen, and a results report returned to the ordering provider indicating whether detected levels are consistent with expected steady‑state exposure.
Typical sites of service include outpatient clinics, pain management centers, addiction medicine clinics, behavioral health clinics, and independent collection sites that coordinate with the laboratory. Indications for testing include monitoring adherence, assessing unexpected toxicology results, evaluating suspected diversion or misuse, and periodic safety checks during chronic controlled‑substance therapy. The specimen type is oral fluid and the laboratory provides an interpreted comparison to steady‑state ranges rather than only a qualitative result.
