Re: Formal Internal Appeal — {{CLAIM_NUMBER}}
I am requesting external review of the final adverse benefit determination issued on {{FINAL_DENIAL_DATE}} for {{SERVICE_OR_DRUG}}.
This request is timely under 45 CFR 147.136(d)(2)(ii), which requires at least four months from receipt of the final internal notice to file.
Grounds:
1. This denial involves medical judgment (medical necessity / experimental-investigational determinations).
2. Substantial clinical evidence, attached, supports coverage — including {{EVIDENCE_LIST}} and the treating physician's letter.
3. All internal appeal levels have been exhausted (final denial attached).
Please forward this request to the appropriate Independent Review Organization (state IRO or federal-HHS process, whichever applies) and confirm receipt in writing.
Sincerely,
{{MEMBER_NAME}}Key points before you send it
- You have at least 4 months (typically 120 days) from the final internal denial to file.
- External review is decided by an Independent Review Organization and is binding on the plan.
