Turn an EOB and line items into a medical-bill dispute letter—you still verify codes, and you strip extra PII.

Protocol

1. 1

   Transcribe line items; do not upload a full chart (5 min).

   Copy provider name, date of service, billed amount, allowed amount, what you paid, CPT/HCPCS/Rev codes as printed, and why you dispute (duplicate, wrong date, not received, already paid). Prefer last four of member ID. Omit SSN and other family members’ claims.

2. 2

   Lock “verify codes / no invented lines.”

   The model may not add a CPT or a law citation you did not supply.

   Copy-paste prompt

   Copy

   Draft a medical-bill dispute letter from the EOB / line items I paste.
   
   Not legal, billing, or medical advice. I will verify every code on the paper statement before I send.
   
   Hard rules:
   - Use only providers, dates, amounts, and codes I typed.
   - Do not invent CPT/HCPCS, diagnosis codes, or statutory citations.
   - If I pasted SSN, full address, or extra family claims, redact and tell me.
   - Do not accuse fraud unless I used that word and gave a fact. Prefer “please reprocess / explain.”
   - Include a request for an itemized bill if I do not have one.
   
   Output:
   1) Letter (addresses as I provided or [NEED ADDRESS])
   2) Table restating each disputed line from my paste
   3) VERIFY list (codes/amounts I must check on paper)
   4) PII redaction note
   
   Confirm the rules, then wait.

3. 3

   Generate the letter, then check the paper EOB.

   Every code in the letter must appear on your statement. If the model added one, delete it.

   Generate command

   Copy

   Here are the line items and why I dispute them. Draft the letter. Do not add codes I did not type. Leave [NEED ADDRESS] if I omitted it. List VERIFY items.

4. 4

   Send through the insurer or provider channel they specify.

   Use the appeal address or portal on the EOB. Keep a copy. If you need a shorter portal comment, use the block below.

   Portal-length comment

   Copy

   Cut the letter to 120 words for a portal box. Keep dates, amounts, and codes exactly as in my paste. No new codes.

When not to

• PII hygiene: strip SSN, full member IDs when last-four will do, extra family claims, and unrelated diagnoses before you paste.
• Verify every EOB code and amount on the paper statement. Do not invent a CPT, diagnosis, or statute.
• This is not legal, billing, or medical advice. Deadlines on the EOB still matter—read them yourself.
• Skip this recipe if you only have a total due and no line items. Request an itemized bill first.
