Billing tips
Bill workers' compensation carriers directly using their specific fee schedules rather than Medicare rates
Impact: Workers' comp rates typically range from $300-$800+ for disability exams compared to Medicare's $0 rate; critical for practice revenue
Establish clear payment policies requiring pre-payment or guaranteed payment from requesting party before scheduling
Impact: Reduces accounts receivable issues by 80-90% as many disability exams are self-pay or third-party arrangements not covered by health insurance
Document the specific requesting entity and claim number on all paperwork to ensure proper routing and payment
Impact: Prevents 60-70% of payment delays and denials related to misdirected claims or lack of authorization documentation
Use state-specific workers' compensation billing codes when required instead of CPT 99455
Impact: Many states mandate proprietary codes with higher reimbursement rates ($400-$1,200) compared to standard CPT coding
Include detailed narrative reports with IME findings as most payers require comprehensive documentation beyond standard medical records
Impact: Complete reports reduce payment disputes by approximately 50% and support higher-tier reimbursement levels for complex evaluations
Verify authorization and pre-certification requirements with the specific workers' compensation carrier or disability insurer before examination
Impact: Prevents non-payment in 40-50% of cases where authorization was required but not obtained prior to service
Common denials
Claim submitted to Medicare or traditional health insurance when service is non-covered
How to appeal: Do not appeal to Medicare. Redirect billing to the appropriate workers' compensation carrier, disability insurer, or establish patient self-pay arrangement. Verify the requesting entity and their payment responsibility before resubmitting.
Lack of prior authorization from workers' compensation carrier or disability insurance company
How to appeal: Contact the requesting entity to obtain retroactive authorization if possible. Provide documentation showing the examination was requested by employer or attorney. If authorization cannot be obtained, pursue payment from the requesting party directly rather than the insurance carrier.
Incomplete or insufficient documentation to support the disability evaluation
How to appeal: Submit a comprehensive IME report including history of injury/condition, physical examination findings, functional capacity assessment, causation analysis, work restrictions, and maximum medical improvement status. Reference specific state workers' compensation reporting requirements if applicable.
Denial stating the exam was not medically necessary or was for administrative purposes only
How to appeal: Acknowledge that this is an administrative examination and should not be processed as a medically necessary health insurance claim. Redirect to workers' compensation, liability insurance, or disability carrier. If exam was patient-initiated for personal use, establish direct patient payment responsibility.
Frequently asked questions
Does Medicare pay for CPT code 99455?
No, Medicare does not cover CPT 99455. This code has a $0 Medicare reimbursement rate because it represents a disability examination for administrative or legal purposes rather than medically necessary treatment. Payment typically comes from workers' compensation carriers, disability insurers, employers, or patient self-pay.
What is the difference between CPT 99455 and a regular office visit?
CPT 99455 is specifically for work-related or medical disability examinations performed for third-party administrative purposes, not for diagnosing or treating the patient. Regular office visits (99202-99215) are for medical care and treatment. Disability exams focus on functional capacity assessment and legal/administrative documentation rather than therapeutic intervention.
How much does a work-related disability exam cost?
Since Medicare pays $0 for CPT 99455, reimbursement comes from alternative sources. Workers' compensation carriers typically pay $300-$1,200 depending on complexity and state fee schedules. Private disability insurers may pay $400-$800. Self-pay rates vary widely by provider and examination complexity, often ranging from $500-$1,500.
Who can bill CPT code 99455?
CPT 99455 must be performed and billed by a physician (MD or DO) or other qualified healthcare professional as defined by the requesting payer. Many workers' compensation programs and disability insurers require board certification in a relevant specialty and specific credentialing for independent medical examiners.
Can I bill 99455 and an E/M code on the same day?
Generally no, because 99455 represents a comprehensive disability evaluation that encompasses examination services. If a separate, unrelated medically necessary evaluation and management service is provided on the same day for treatment purposes, modifier 25 may be appropriate with the E/M code, but the services must be clearly distinct and separately documented.
What documentation is required for CPT 99455?
Documentation must include a formal IME report with the requesting party's identity, authorization details, injury/condition history, comprehensive physical examination, functional capacity assessment, causation analysis, work restrictions, and opinions on disability status. Most workers' compensation jurisdictions have specific reporting format requirements that must be followed.
How do I get paid for 99455 if Medicare doesn't cover it?
Establish clear payment arrangements before the examination. For workers' compensation cases, bill the carrier directly using their fee schedule and claim number. For disability insurance exams, verify the insurer's payment process. For attorney-requested or employer-direct evaluations, require payment in advance or establish a contract for guaranteed payment. Never submit to Medicare or standard health insurance.
