Master Compliance in Toxicology Billing

Toxicology and substance abuse lab billing faces intense payer scrutiny. From navigating presumptive vs. definitive testing to managing Medicare G-codes and strict medical necessity edits, we protect your lab’s revenue.

Lab Diagnostics

Presumptive vs. Definitive

We accurately separate initial screening codes (CPT 80305-80307) from complex LC-MS/MS confirmatory tests to prevent automated unbundling denials.

Why Toxicology Needs Specialized Experts

Toxicology billing is heavily audited. Payer policies constantly change regarding how many definitive drug classes can be billed per day, and "blanket testing" orders without custom medical necessity are immediately rejected. We ensure your lab operations translate into compliant, highly-paid claims.

Medicare G-Code Compliance

While commercial payers use CPT codes for definitive testing, Medicare strictly requires G-codes (G0480-G0483) based on the number of drug classes tested. We automate this mapping.

Medical Necessity Edits

Custom drug panels are heavily scrutinized. We ensure that every requisition form includes the proper ICD-10 diagnosis codes linking the specific drug test to the patient’s clinical condition.

CLIA Modifier (QW) Application

For labs utilizing point-of-care or CLIA-waived testing devices, we strictly apply the QW modifier to prevent immediate technical rejections from Medicare and Medicaid.

The Lab Billing Workflow

Securing Revenue from
Requisition to Remittance

We seamlessly integrate with your Laboratory Information System (LIS) to catch missing diagnoses and medical necessity errors before the claim is ever generated.

01

LIS Data Integration

We connect directly with your Laboratory Information System (LIS) to pull clean demographic, insurance, and requisition data, minimizing manual entry errors.

02

Payer-Specific Scrubbing

Our rule-engine dynamically swaps standard CPT codes for Medicare-specific HCPCS codes depending on the primary payer listed on the patient’s file.

03

MUE & Frequency Limits

Toxicology is strictly limited by Medically Unlikely Edits (MUE). We ensure you don’t bill more presumptive or definitive units per day than the payer’s strict threshold allows.

04

Audit Defense & Appeals

When payers deny claims demanding proof of custom physician orders (rather than blanket panels), our appeals team retrieves the signed requisitions to overturn the denial.
