Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Draft a clear appeal letter for a Medicare claim that was denied as not medically necessary, using only the facts I give you.

Questions to ask me first:
- What service was denied, on what date, and what reason did the denial notice give?
- What made the service necessary on that day (diagnoses, mobility, symptoms)?
- Do you have the notice's appeal deadline and claim number handy (don't paste the full Medicare number)?

Inputs (fill in or confirm):
- Service and date: [SERVICE / DATE]
- Denial reason as written on the notice: [REASON]
- Medical facts that day: [FACTS]
- Who ordered or arranged the service: [ORDERING PROVIDER]
- Appeal deadline: [DEADLINE]

Rules:
- First explain in plain words what the denial reason means and what Medicare usually looks for, and say where I should confirm it on Medicare.gov or the notice.
- Use only facts I give you; mark anything you're unsure of as [CHECK].
- Keep the letter to one page, polite and specific.
- List the supporting records I should attach, such as the discharge summary or a doctor's note.

Checkpoint: Show me the plain-language explanation and a short outline of the argument, and wait for my corrections before writing the letter.

If you get stuck: If you don't know a Medicare rule, say so and tell me what to ask the provider or 1–800-MEDICARE instead of guessing.

Verify before you finish: Check every name, date and medical detail in the letter against my inputs and list any you had to assume.

Output: A plain-language summary of the denial, then the appeal letter, then a checklist of attachments.

Done when: I have an accurate letter I can sign and file before the deadline.

Outcome

Theresa Hupp's husband, who has Parkinson's, spent a month in the hospital and was taken to a rehab center by an ambulance the hospital arranged. Medicare denied the claim because the trip wasn't an emergency and was deemed not medically necessary. Hupp first asked Gemini plain-language questions to learn the Medicare terms, then asked it to draft an appeal letter from the facts of the case. The first draft had some wrong details and needed heavy editing, but Hupp estimates it gave about 80 percent of what was needed. After correcting the facts, Hupp filed the appeal. Medicare accepted the claim and paid its portion, the secondary insurance paid its share, and the bill had been over $1000.

Evidence: Described by posterThe person describes what happened in words, without screenshots or video.
