Stop losing revenue to coding errors, medical-necessity denials, and payer-level scrutiny. Our toxicology billing company delivers 98.5%+ clean claims, ≤4% denial rates, and 20%+ typical revenue uplift without disrupting your clinical workflow.
The Problem
In 2026, lack of proper medical necessity documentation is among the most common reasons for definitive toxicology test denials with some Medicare review data showing it as the leading denial cause for G0480–G0483 claims. We fix the documentation gap before the claim is filed, so every test has proper clinical justification and eligible reimbursement.
Challenges
Beyond lost revenue, labs face compliance and operational pressures:
Fear that commission-based sales or lab partnerships could trigger a federal investigation.
CMS/OIG audits from miscoded claims, missing documentation, or reflex testing errors.
One high-tier denial can freeze thousands of dollars for months.
"Insufficient medical necessity" is the #1 cause of definitive drug test denials.
Navigating payer rules and EKRA compliance distracts from patient care.
Services
We serve physician offices, labs, pain management, addiction medicine, and behavioral health practices with end-to-end toxicology billing solutions:
Coding
Toxicology billing is complex: presumptive vs definitive testing, tiered panels, and reflex logic all affect payment. Our certified team specializes in drug testing lab billing, handling presumptive and definitive tests, Z-Code identifiers, and G0480–G0483 tiers.
