Working tools, not demos. No account, no card, no email.
Free ICD-10 claim scrubber
Paste the diagnosis codes from a claim and get back what would reject it: Excludes1 conflicts, non-billable header codes, missing 7th characters, laterality contradictions, and unmet sequencing rules.
Denial appeal letter generator
Pick the denial code, fill in the claim, and get a professional appeal letter that opens with the argument that wins that specific code. Runs entirely in your browser — nothing you type is sent or stored.
Free RVU calculator
Enter the work, practice-expense and malpractice RVUs, pick your locality, and get the Medicare allowed amount with the whole GPCI and conversion-factor breakdown shown. Both CY2026 conversion factors, every Medicare locality.
ICD-10-CM code lookup
The complete FY2026 code set with coding notes, exclusions, 7th-character rules, and the full hierarchy. No ads, no paywall.
HCPCS Level II code lookup
Drugs, supplies, equipment and the services CPT does not cover. Every code with its Medicare coverage status and how the physician fee schedule treats it — which is the field that decides whether you get paid.
