Hospital Observation-Status Watchdog is a startup idea for adult children, family caregivers, and seniors. Families learn at discharge that their mother spent three days 'under observation', not admitted, so Medicare won't cover rehab and a surprise $12,000 bill arrives. A thread in r/AgingParents drew 46 upvotes and 15 comments between Sep 14, 2026 – Oct 14, 2026. People get by with Medicare MOON notice and Patient advocates, and that still leaves this job open. Hotness is 3.70, Hot. Severe, costly pain. Clear willingness to pay. The thread drew 46 upvotes and 15 comments. No real solution exists. Needs integrations or data deals. A first version is a hard build, about 5+ weeks, priced between $10 and $49 a month and charged as a subscription. The pain, the source, the alternatives, the scope notes, and the questions on this page are free to read and free to build from. The agent starter prompt is the paid part. The first slice is on the page. One credit unlocks the rest, to paste into a coding agent, download as Markdown, or send as a private link.

Who has it
Adult children, family caregivers, and seniors.
What people use now
- Medicare MOON notice
- Patient advocates
A way through
Track a patient's admission status via hospital portals in real time, notify the family when observation status threatens coverage, and supply appeal templates.
MVP scope
- Give adult children, family caregivers, and seniors a way to do this in one sitting: Alert families the moment a parent is billed as 'observation' instead of 'inpatient', before Medicare coverage is lost.
- Persist the result and show it again after a reload.
- State the empty case when there is nothing to show yet, with one next step.
- Charge later with a subscription, between $10 and $49 a month. The free path must finish the core job once.
- Ship the web app only. Leave Medicare MOON notice to keep the jobs they already do well.

Questions
Is this idea already taken?
People already use Medicare MOON notice, Patient advocates. Those options do not do the job in the solution above. The idea is free to build. Nothing here is an exclusive claim.
How hard is a first version?
Hard. A tight MVP is about 5 weeks (5+ weeks), assuming the regulated or partner-gated parts are stubbed. The paid prompt turns that into tasks.
Who would pay, and how?
The audience is adult children, family caregivers, and seniors. Charge a subscription, and test a price between $10 and $49 a month. Willingness to pay is one input to Hotness, not a promise that someone will buy.
Can I use the evidence?
Yes. Build the product. The thread title is a short excerpt with a link, not a quote we are putting in someone's mouth. Exact post dates and verbatim lines are added only after a manual check. Ideas are suggestions, not medical, legal, or financial advice.
