An insurance appeal letter is a formal request to overturn an insurance company's denial of coverage for a medical service, procedure, or medication. When insurers deny claims — often citing "medical necessity" concerns or policy exclusions — an appeal letter presents clinical evidence and policy-based arguments to reverse the decision.
Appeal letters must be thorough, well-organized, and compelling. They require citing specific policy language, presenting clinical evidence, referencing medical guidelines, and clearly articulating why the denial should be overturned. Many practices find writing appeals more time-consuming than the original prior authorization request.
DocDraft's AI appeal letter generator transforms this burdensome process into seconds. Input the denial reason, your clinical justification, and why coverage is warranted — AI creates a persuasive, evidence-based appeal letter ready to submit.
Insurance Appeal Letter Example
APPEAL OF DENIED CLAIM — MRI Lumbar Spine
Claim Reference: PA-2026-003894
Date: March 9, 2026
To: Blue Cross Blue Shield Appeals Department
PATIENT: Robert Johnson, DOB 3/15/1958
REASON FOR APPEAL: Overturn denial of MRI lumbar spine (CPT 72148)
ORIGINAL DENIAL REASON:
Claim denied citing "insufficient documentation of conservative treatment failure" and "medical necessity not established."
CLINICAL JUSTIFICATION FOR REVERSAL:
Mr. Johnson presents with chronic low back pain with radiculopathy extending to the left lower extremity, rated 7/10 in severity, significantly impacting his ability to work and perform daily activities.
CONSERVATIVE TREATMENT DOCUMENTED:
- Physical therapy: 8 weeks (12 sessions completed 1/10/26 - 3/1/26), minimal improvement documented
- NSAIDs: Ibuprofen 800mg TID x 4 weeks, then meloxicam 15mg daily x 4 weeks — inadequate pain control
- Muscle relaxants: Cyclobenzaprine 10mg QHS x 3 weeks — no significant benefit
- Activity modification and home exercise program — ongoing, minimal relief
MEDICAL NECESSITY:
Physical exam reveals positive straight leg raise test on the left, decreased sensation in L5 dermatome, and 4/5 strength in left ankle dorsiflexion. These findings suggest nerve root compression requiring imaging evaluation to guide further treatment and rule out surgical indications.
Per American College of Radiology Appropriateness Criteria and your own policy guidelines (Section 4.2.3), MRI is indicated for low back pain with radiculopathy after 6 weeks of failed conservative care. This patient has completed 8 weeks of comprehensive conservative treatment without adequate improvement.
REQUESTED ACTION:
I respectfully request reversal of the denial and authorization for MRI lumbar spine without contrast (CPT 72148) to appropriately evaluate this patient's neurological compromise and guide evidence-based treatment planning.
Sincerely,
Dr. Emily Rodriguez, MD
