Pathology Revenue Cycle Management Built for High Volume
Pathology billing is about managing large volumes of lab tests with payer-specific documentation and modifier rules. AnnexMed’s pathology medical billing services cover intake to collections: order validation, eligibility checks, CPT/ICD mapping, split-billing, and denials management. Whether you’re billing for hospital-based pathology, reference labs, or physician practices, we adapt workflows to match your setting.
Pathology Billing Challenges That Block Revenue
Billing for chiropractic services goes beyond adjustments. Without precise coding and documentation, claims often stall or get denied.
-
Specimen Documentation Errors
Missing patient identifiers, collection dates, or test details cause claim delays and payer denials. -
Bundling & Unbundling Errors
Incorrect separation of panel codes or unbundled tests creates compliance risks and lost revenue.
-
Split-Billing Mistakes
Incorrect application of modifiers (-26, -TC) leads to reimbursement misallocation between providers and labs. -
High-Volume Claim Backlogs
Thousands of daily pathology claims overwhelm staff, delaying submissions and affecting cash flow cycles.
-
Medical Necessity Denials
ICD-10 codes that don’t justify tests under payer policy stall pathology claim payments. -
Complex Payer Variations
Different pathology coverage rules across payers increase rework and claim rejection rates significantly.
