2 things to look at

  • 24 days oldThe repository was created 24 days ago. New is not bad, but a brand new repository carrying a familiar-sounding name is the shape a typosquat arrives in, and there has been no time for anyone else to find a problem with it.
  • 1 stars1 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Audit an itemized medical bill for errors — duplicates, upcoding, unbundling, phantom charges. Use once an itemized bill with CPT codes is in the case folder.

Review the itemized bill

Prereq: an itemized statement with CPT/HCPCS codes in the case folder. If there isn't one, send the request first (templates/letters/itemized-request.md) — never audit a summary bill.

Steps

  1. Transcribe every line into a table in case.md: date, CPT/HCPCS, description, units, charge. Reading the bill into structured data IS the audit's foundation — most errors surface here.

  2. Decode the codes. For each CPT, state in plain English what it is (and its E/M level if it's a visit code). Flag anything that doesn't match the story from intake. The user was there — walk the timeline with them: "You're billed for two chest X-rays — do you remember two?"

  3. Run the error checklist (details in knowledge/tactics.md §3 and knowledge/glossary.md). Billing departments have insider names for the big four — use them; they signal you know the game:

    • "Double dip" — duplicates (same code + date, or same service under two revenue codes)
    • "Level creep" — upcoding (ER E/M level vs. what happened; observation billed as admission)
    • "Unbundling" — components billed alongside their bundle code
    • "Phantom charges" — drugs/supplies/tests not received; ordered then canceled but billed
    • Quantity errors (units column!) and impossible times (OR minutes, room days — the discharge-day room charge is a classic)
    • Room-type charges: private-room rates for shared rooms. The hospital's bed-management system logs every room/bed assignment by shift (ADT — admission/discharge/transfer records). Request them for any inpatient stay with room charges — see the optional items in templates/letters/records-request.md.
    • Wrong patient, date, or provider lines
    • If insured: EOB mismatch — any line where the provider's ask exceeds the EOB's patient responsibility

  4. Score each finding: confirmed error / suspicious (needs their records) / fine. For "suspicious," the follow-up is a HIPAA records request (templates/letters/records-request.md) — medical records vs. bill is the definitive comparison.

  5. Write the dispute. Confirmed + suspicious items go into templates/letters/error-dispute.md, itemized with codes, one paragraph per item, and land in letters/ for user approval. Disputed amount is frozen; undisputed remainder proceeds to benchmark-price → strategy.

Never assert fraud — assert "these charges appear inconsistent with the services received" and request correction and a corrected statement.
