MEDICAL NECESSITY LETTER
Medical Necessity Letter Generator
When a claim is denied or hours are cut, this is the document that answers it. It states what the client cannot do, why the service requires a licensed clinician, and what you are requesting.

How this works
What a reviewer actually decides on
Not whether therapy helps — almost everyone agrees it helps. The decision is whether the service requires a licensed clinician rather than a caregiver or a non-skilled provider. Every sentence in a strong necessity letter is aimed at that single question.
The three statements that carry the weight
First, what the client currently cannot do. Second, the level of assistance required to attempt it. Third, why that level of assistance exceeds what an untrained person can safely provide. The generator writes all three from your assistance and goal selections, then adds your documented response to show the plan is working.
Progress is not the opposite of necessity
A common mistake is showing so much progress that the payer concludes services are no longer needed. The fix is framing: improvement demonstrates the plan is effective and supports continuing it, rather than showing the work is finished. The improved-response language is written with that framing in mind.
Match the request to the denial
If hours were reduced, state the specific frequency and duration you are requesting. A letter that argues necessity without stating a number is easy to file and ignore. The frequency and duration fields generate an explicit authorization request.
Questions
Common questions
Should a necessity letter be written on letterhead?
Usually yes, with your credentials, license number, and date. Copy the generated text into your letterhead document and export from there.
How long does the letter need to be?
One page if you can manage it. Reviewers read hundreds. Detailed setting produces a long version when a denial specifically cited insufficient clinical detail.
Can I use this for a peer-to-peer review?
Yes — the same content works as talking points. The three statements above are also the structure that wins a peer-to-peer conversation.
