Funding Justification Letter
A formal document authored by a qualified clinician that provides clinical rationale, functional assessment findings, and equipment specifications to support an insurance or government funding request for a rehabilitation technology device.
Full Definition
A funding justification letter (sometimes called a letter of medical necessity in US contexts) is a structured clinical document that must demonstrate medical necessity, functional benefit, and the appropriateness of a specific piece of equipment over lower-cost alternatives. It typically includes a diagnosis, functional limitations, trial results, and a statement that the device is the least costly clinically appropriate option. In rehab technology, these letters accompany claims for complex wheeled mobility, AAC devices, and upper-limb prostheses. Editors must ensure consistent terminology between the letter and the accompanying prescription, correct HCPCS codes where cited, and verify that the clinician's credentials and signature block meet payer requirements.
Usage
Usage note: Distinguish from a 'prior authorisation request,' which is a payer-facing administrative form; the funding justification letter is the clinical narrative that accompanies it. Ensure equipment descriptions match HCPCS codes exactly.
