Claim scrubbing and denial resolution
Scrub the claim before you send it. Resolve the denial after you get it.
Enter a payer, a date of service and your billed lines. See which lines will bundle, which exceed a medically unlikely edit, which modifier would legitimately resolve it, and the CMS citation behind each verdict. Free to scrub one claim at a time in your browser. Pro adds batch scrubbing, saved history, appeal letters and the API.
The claim scrubber, every CARC and RARC page, and the API are free, need no account, and cite the source behind every verdict.
What you get
A cited verdict, a private free tool, and an API for agents
Scrub before you submit
Enter a payer, a date of service and your billed lines. See which lines an NCCI procedure-to-procedure edit will bundle, which exceed a medically unlikely edit, which modifier would legitimately resolve it, and the CMS citation and edit quarter behind every verdict.
See how the engine worksResolve the denial after it lands
Give it a CARC and any RARCs off the remittance. It explains what actually happened in plain terms, ranks the corrective actions, tells you whether an appeal is worth filing, and drafts the appeal letter with the citations that support it.
See what is free vs paidClaim data never leaves your browser
The free scrubber runs entirely client-side. Your payer, date of service and billed lines are never transmitted to a server. That is a deliberate architecture choice, not a policy promise: there is no network call to make.

The same engine is a single-key REST API and an MCP server, so an autonomous medical billing agent can scrub a claim or resolve a denial mid-task and get a cited answer back, not a guess.
Read the API docsNo edit in our dataset is not a pass
Our NCCI PTP and MUE datasets are curated subsets of much larger CMS files, and every row carries the source it came from and a confidence flag. When a code or pair is not in our loaded dataset, the verdict says exactly that: not checked, no edit in our dataset. It is never rendered as a pass, and it is never coloured green. See the methodology page for our real coverage, stated plainly.

Common questions
What does DenialPath actually do?
Two jobs. Before you submit a claim, it checks the billed lines against CMS NCCI procedure-to-procedure edits and medically unlikely edits in force on the date of service, and tells you which lines will bundle, which exceed a unit limit, and which modifier would legitimately resolve it. After a denial arrives, give it the CARC and any RARCs off the remittance and it explains what happened, ranks the corrective actions, and can draft the appeal letter.
How do you avoid reporting a false pass?
Every PTP pair and MUE code we hold comes from a CMS file with a source link and a confidence flag. Where we hold no edit for a code or pair, the finding status is "no data", never "pass". A claim with unchecked lines is reported as unchecked, not clean, because a biller acting on a false green light loses real money.
Is the free scrubber really private?
Yes. The scrubbing engine is plain, dependency-free TypeScript that runs in your browser tab. Scrubbing one claim in the free tier makes no request to our servers, so there is nothing to intercept and nothing stored unless you choose to save the result on a paid plan.
Is it free?
Yes to start. The single-claim scrubber, every CARC and RARC denial page, and a throttled test API key are free with no card. Pro ($49/mo) adds batch scrubbing, saved claim history, appeal letter generation and a production API key, because a working biller processes claims in volume, not one at a time.
Can an autonomous billing agent use it?
Yes, that is a first-class use case, not an afterthought. The REST API and hosted MCP server expose the same engine as check_claim, explain_denial, get_ncci_edits, get_mue, draft_appeal and get_timely_filing tools, so an agent can scrub a claim or resolve a denial mid-task with a citation it can show its user.
Is this medical or legal advice?
DenialPath provides billing and administrative guidance based on published CMS and X12 sources. It is not medical advice, not a coverage determination, and not a guarantee of payment. NCCI and MUE edits are republished quarterly and payer policies vary by contract. Always confirm against the payer's own current policy before submitting or appealing.
