What Is Laboratory Billing?
Clinical laboratory billing services cover the complete revenue cycle for diagnostic laboratories, including requisition intake, eligibility verification, CPT/ICD-10/HCPCS coding, claim submission, payment posting, and denial management. Laboratory billing also involves specialty-specific requirements that differ from standard physician billing.
Panel Coding Rules
Laboratory panels must be billed according to applicable panel coding rules. Incorrectly unbundling panel components or combining tests that should be billed separately can result in denials or lost reimbursement.
Molecular and Genetic Testing
Molecular and genetic testing may require prior authorization, clinical indication documentation, and other payer-specific requirements. These high-value claims require careful billing and documentation.
Medical Necessity and ABN Management
The diagnosis on the requisition must support the test being performed. When Medicare coverage is uncertain, appropriate Advance Beneficiary Notice (ABN) documentation may also be required.
Toxicology and Definitive Testing
Toxicology billing involves distinctions between screening and confirmation, presumptive and definitive testing, specimen validity testing, quantitative and qualitative results, and payer-specific frequency requirements.
CLIA Modifier Billing
CLIA modifiers such as QW, 90, and 91 can affect how laboratory services are billed. Accurate modifier application helps prevent avoidable claim denials.
Ordering Provider and Requisition Requirements
Missing NPIs, signatures, diagnoses, or incomplete requisitions can create avoidable billing problems. Reviewing documentation before claim submission helps reduce these issues.
Our Laboratory Revenue Cycle Management Process
Med Bridge follows a six-step laboratory billing process designed to identify billing issues before they become denials.
Requisition Intake & Eligibility Verification
We review requisitions for ordering provider NPI, diagnosis, signature, and test selection. Eligibility checks confirm coverage, deductible status, and applicable Medicare ABN requirements.
Laboratory Charge Capture
Each laboratory service is converted into appropriate billable line items. We review chemistry, hematology, microbiology, toxicology, molecular, and pathology services for accurate charge capture and panel logic.
Lab-Specific Medical Coding
Certified coders apply CPT, ICD-10, and HCPCS codes along with applicable CLIA modifiers, professional/technical components, and panel coding rules.
Claim Scrubbing & Submission
Before submission, claims are reviewed for coding issues, missing modifiers, medical necessity mismatches, missing documentation, and applicable NCCI edits.
Payment Posting & Remittance Reconciliation
ERA and EOB payments are posted and compared against expected reimbursement. Underpayments and discrepancies are identified for follow-up.
Denial Management & Appeals
Denials are reviewed promptly and appealed with supporting requisition documentation, medical necessity information, and applicable payer or regulatory requirements. Recurring denial trends are tracked to address root causes.
Eligibility Verification
We review requisitions for ordering provider NPI, diagnosis, signature, and test selection. Eligibility checks confirm coverage, and applicable Medicare ABN requirements.
