Billing tips
Establish written fee agreements before examination since Medicare pays $0; typical market rates range from $500-$2000 depending on complexity and time required
Impact: Prevents revenue loss and ensures clear payment responsibility with requesting entity before service delivery
Bill the requesting entity directly (insurer, attorney, employer, or agency) rather than the patient or Medicare, using a superbill or invoice rather than CMS-1500
Impact: Ensures appropriate payment channel since this is a non-covered Medicare service with 0.00 total RVUs
Document examination time meticulously and consider time-based billing if contractual agreement allows, as disability exams often exceed 60-90 minutes
Impact: Can increase reimbursement 50-100% when time exceeds base examination expectations with third-party payers
Obtain advance authorization and deposit/prepayment from requesting entity, as many disability examinations are disputed or cancelled after completion
Impact: Reduces bad debt risk which averages 15-25% for disability examination services without prepayment
Use modifier 32 consistently to distinguish mandatory third-party examinations from voluntary patient-initiated evaluations
Impact: Clarifies non-covered status and supports medical necessity documentation for alternative payment processing
Maintain separate contracts and fee schedules for different requesting entities (workers' comp, SSA, private insurers) as rates vary significantly
Impact: Optimizes revenue by matching market rates; workers' comp may pay 30-50% more than private disability carriers

Frequently asked questions
Does Medicare pay for CPT code 99456?
No, Medicare does not reimburse CPT 99456. The 2025 Medicare rate is $0.00 with 0.00 total RVUs, making this a non-covered service. Disability examinations must be billed directly to the requesting entity such as an insurance company, employer, attorney, or government agency.
Who pays for a CPT 99456 disability examination?
The requesting entity pays for disability examinations, not Medicare or the patient's insurance. This includes workers' compensation carriers, disability insurance companies, Social Security Administration, employers, or attorneys who ordered the independent medical evaluation. Payment arrangements should be established in writing before the examination.
How much should I charge for CPT 99456?
Since Medicare pays $0, providers set their own fees based on market rates and contractual agreements. Typical charges range from $500 to $2,000 depending on examination complexity, specialty expertise required, time involved, and geographic location. Workers' compensation examinations often command higher rates than private disability evaluations.
What is the difference between CPT 99456 and regular E&M codes?
CPT 99456 is specifically for disability examinations performed for third-party administrative purposes, not for diagnosis or treatment. Regular E&M codes (99202-99215) are for patient care encounters covered by insurance. Disability exams are non-covered by Medicare, require different billing processes, and are paid by requesting entities rather than patient insurance.
Can I bill the patient for a 99456 examination?
Generally no, unless the patient specifically requested and agreed in writing to pay for the examination themselves. Typically, the requesting third party (insurer, employer, attorney) is financially responsible. Billing the patient without clear advance agreement can create ethical and legal issues, especially for mandatory examinations.
What modifier should I use with CPT 99456?
Modifier 32 is most commonly used with CPT 99456 to indicate the service was mandated by a third party (insurer, legal entity, or payer) rather than requested by the patient. This modifier helps document that the examination was not patient-initiated and justifies billing to the requesting entity rather than patient insurance.
How do I bill for a disability examination if not through Medicare?
Bill the requesting entity directly using a superbill, detailed invoice, or their specific billing form rather than a CMS-1500 claim. Include CPT 99456, your contracted rate, examination date, detailed report, and any required authorization numbers. Many entities have specific billing portals or require submission through their vendor management systems rather than standard claims processing.
