RE: Formal dispute of charges, Account #[ACCOUNT NUMBER]
Patient: [PATIENT FULL NAME]
Date(s) of service: [DATE OF SERVICE]
Statement date: [STATEMENT DATE]
Total currently billed: $[CURRENT BALANCE]
Total disputed: $[TOTAL DISPUTED AMOUNT]
Dear Billing Department:
I am writing to formally dispute specific charges on the above-referenced account. I have reviewed the itemized statement and identified the following issues:
[For each finding, the LLM renders one of the blocks below. Number them sequentially.]
[BLOCK A, Price exceeds fair-market rate]
1. Line item: [CPT or service description]
Charged: $[AMOUNT CHARGED]
Fair-market rate for this CPT/HCPCS code in this geographic area: $[FAIR PRICE RANGE]
Source: [Turquoise Health / FAIR Health Consumer / Healthcare Bluebook / hospital MRF, include URL or attached printout reference]
Overcharge: $[CHARGED − FAIR HIGH]
Position: The charged amount is approximately [N]× the fair-market range. Pursuant to Uniform Commercial Code § 2-305(2), a price to be fixed by the seller "means a price for him to fix in good faith." The current price does not appear to meet that standard. I propose a corrected charge of $[PROPOSED CORRECTED AMOUNT, typically the upper end of fair-market].
[BLOCK B, CPT severity coded too high]
2. Line item: CPT [CODE], [description]
Charged: $[AMOUNT CHARGED]
Issue: CPT [CODE] requires [MDM complexity / time threshold] per the AMA's E/M documentation guidelines. The actual encounter on [date] involved [duration in minutes / problems addressed / decision-making complexity]. The appropriate code is [LOWER CODE]. The price difference attributable to incorrect coding is approximately $[OVERCHARGE].
Position: Please recode to [LOWER CODE] and issue a corrected bill, or provide the clinical documentation that supports the higher-level code as currently billed.
[BLOCK C, Duplicate charge]
3. Line item: [description], appears [N] times on [date]
Charged: $[AMOUNT × N]
Issue: This appears to be a duplicate of [reference line]. The same service does not appear in the clinical record [N] times.
Position: Please remove [N−1] of the [N] duplicate entries, reducing the charge by $[AMOUNT × (N−1)].
[BLOCK D, Service not received]
4. Line item: [description]
Charged: $[AMOUNT]
Issue: I have no record of receiving this service on [date]. My recollection of services received that day is: [summary].
Position: Please remove this line item or provide contemporaneous clinical documentation that the service was rendered.
[BLOCK E, Improper bundling]
5. Line items: [description A, CPT X] and [description B, CPT Y]
Charged: $[A] + $[B] = $[total]
Issue: CMS National Correct Coding Initiative (NCCI) edits indicate that CPT [X] and CPT [Y] should not be billed together for the same date of service; one is included in the other. Source: CMS NCCI edits, current quarter.
Position: Please remove the bundled component (CPT [Y or X]), reducing the charge by $[AMOUNT].
[END OF BLOCKS]
Summary of dispute:
Currently billed: $[CURRENT BALANCE]
Total disputed (above): $[TOTAL DISPUTED]
Proposed corrected total: $[CURRENT BALANCE − TOTAL DISPUTED]
I am prepared to pay $[PROPOSED CORRECTED TOTAL] upon receipt of a corrected itemized statement reflecting these adjustments. I am not refusing to pay; I am declining to pay charges that are erroneous, mis-coded, or unjustifiably above market rates.
Legal references:

- [As applicable: state itemization statute, e.g. Tennessee Code § 68-11-220]
Please send a corrected, itemized statement and a written response to the points above within fifteen (15) business days of the date of this letter. If I do not receive a substantive response by [DATE 15 BUSINESS DAYS FROM TODAY], I will escalate this matter through additional channels, which may include a formal complaint to the [STATE INSURANCE / HEALTH DEPARTMENT], a complaint to the Centers for Medicare and Medicaid Services if applicable, and other available remedies.
If you have any questions, please contact me at the phone number or email above.

- The LLM renders only the blocks that apply to this bill's findings. A bill with one price-gouging line and no other findings renders only Block A.
[TOTAL DISPUTED AMOUNT]is the sum of overcharge amounts across all rendered blocks.[PROPOSED CORRECTED TOTAL]iscurrent_balance − total_disputed.[DATE 15 BUSINESS DAYS FROM TODAY]is calendar arithmetic skipping Saturday/Sunday and federal holidays.- State-specific citations are pulled from
references/laws_state_template.md.
- If the bill is a balance bill that the No Surprises Act prohibits, use
letter_no_surprises_violation.mdinstead. The NSA argument is stronger and stands on federal law. - If this is an insurance denial, use
letter_insurance_appeal_erisa.mdinstead. The audience is the plan administrator, not the provider's billing department.
The LLM logs this action with action_type = "initial_dispute_letter_sent" and sets response_due_by to 15 business days from today.
