Market size · estimate
How big this could get
A bottom-up estimate for Medical Bill Dispute for Services You Never Consented To: real customer counts × a realistic price. Not a forecast.
$1.3B a year
10M patients · 10% of US adults with health care debt
$125M a year
1M patients · US, online
$1.3M a year
10,000 patients · 1% of the reachable segment in three years
What that means
10,000 patients a year × ~$125 = $1.2M a year in revenue
Low confidenceHow we estimated this
- Base: 100,000,000 US adults with health care debt.
- Has the problem: 10% (assume 1 in 10 has a bill for care they did not agree to).
- Revenue per patient: $125 per year (25% success fee on ~$500 saved).
- Reachable: 10% (US, online).
- Three-year capture: 1% of the reachable segment.
TAM = customers with the problem × revenue per customer. SAM = the part an early product can reach. SOM = a conservative three-year share of SAM. Bars use a log scale. Shares marked “assume” are our judgment, not measured.

Is this idea already taken?
People already use Patient advocates, Resolve, Goodbill. 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?
Weekend-easy. A tight MVP is about 2 weeks (2 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 patients and consumers. Charge a fee when the job succeeds, 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.
