ABOUT INPLAN

Provider network answers, with the evidence attached.

InPlan tells your product which marketplace and Medicare Advantage plans list a provider, plan by plan. Every answer carries its source type and the date the data was read.

One provider, fanned out to every plan that lists them: Michael Williard, MD, Orthopedic Surgery, Gahanna, OH (NPI 1184617268) is listed in 38 marketplace plans for 2026 from 3 insurers and 36 Medicare Advantage plans for 2027, each with the date its directory was read.

Why InPlan exists.

Insurers publish their network directories, and national registries list every provider. The data is public. It also comes in many shapes, on many schedules.

Teams that route patients to care end up building pipelines to answer one question: does this plan list this provider? We do that work once. We read the directories, match providers to plans, keep the date on every row, and serve the answer through one API.

Network status drives real decisions: which plan to buy, which doctor to book. So the answer has to be plain, and it has to come with its proof.

The rules we work by.

They decide what we build, what we say on this site and what every answer contains.

01Evidence on every answerEvery answer carries its receipt: source type, network tier, plan year and the date the data was read.
02Never invent a "no"If current directory data does not list a provider, the answer is "Not found". We say exactly that, so your product can ask the user to confirm.
03No patient dataWe hold provider and plan data only. Your requests never need anything about a patient.
04Plain answers, public pricesListed or not found, with the evidence. Our prices are on our site, and anyone can start with 500 free calls.
