The evidence

The closed library behind every letter.

Merits only quotes from the sources below — matched to your exact code, plan type, and payer, quoted word for word, and re-checked against the source before you see the letter. Anything unsupported is flagged for your review, never stated as fact.

484
insurer policies cited — across 43 insurers
40,000+
external-review rulings, studied for what overturns a denial
1.7M
coding rules — NCCI, ICD-10 & HCPCS
0
invented citations — the closed corpus won't allow one

43 insurers' own medical policies — 484 in all

their published coverage criteria, quoted back to them in an appeal to that same payer

Medicare coverage determinations

the LCDs and NCDs for your exact procedure code, with the live criteria

40,000+ external-review rulings

real rulings from independent review organizations — what reviewers actually accept, not what the policy says on paper

240 FDA-approved drug labels

the on-label indication for the high-cost drugs behind the biggest denials

1.7M coding rules — NCCI, ICD-10 & HCPCS

every active coding edit matched to your procedure pair, flagging the technical ground the denial rests on

The federal appeal-rights law

ERISA, ACA, and Medicare appeal rights, captured word-for-word

Clinical & specialty guidelines

USPSTF and specialty-society criteria (e.g. ACR appropriateness), matched by code

State external-review rules

deadlines and external-review rights, mapped across all 50 states + DC

Sources are re-verified on every citation; a source that goes dark leaves the pool automatically. Regulatory text is captured verbatim from the eCFR and U.S. Code — never paraphrased.
