Work related disability exam
CPT 99455 is used when a doctor performs a comprehensive examination to evaluate whether a work-related injury or illness has caused a disability. This is typically done at the request of an employer, insurance company, or workers' compensation board to determine disability status and work capacity.
This calculator gives a typical-case estimate using standard Medicare modifier rules. Actual payment depends on payer policies, documentation, code-specific CMS status indicators, and locality. Verify before billing.

Billing tips
Do not bill Medicare for 99455 as it is non-covered; always verify the appropriate third-party payer (workers' compensation, disability insurer, or employer)
Impact: Prevents automatic denials and delayed payment; workers' comp fee schedules often pay $500-$1500 depending on complexity and state
Obtain pre-authorization from the requesting entity and confirm the specific fee schedule or contracted rate before performing the examination
Impact: State workers' compensation rates vary 200-300% between jurisdictions; pre-authorization ensures payment commitment
Bill the requesting party directly (employer, insurance carrier, or attorney) rather than the patient, and clearly document who ordered the examination
Impact: Prevents patient balance billing issues and ensures proper payment source; improves collection rate by 60-80%
Use detailed narrative reports with specific functional capacity assessments, causation analysis, and disability ratings as required by the requesting entity
Impact: Comprehensive documentation justifies higher complexity payments and reduces disputes; may increase reimbursement by 20-40% for complex evaluations
Consider using state-specific workers' compensation codes when applicable instead of CPT 99455, as some jurisdictions have unique coding requirements
Impact: Some states require proprietary codes or have fee schedules that pay 30-50% higher for state-specific codes
Clearly separate any treatment services from the disability evaluation; bill evaluation and treatment encounters separately to avoid bundling disputes
Prevents downcoding or denial of legitimate treatment services that should be billed under standard E/M codes
