**Re: Appeal of Denied Claim #HL-2026-001234 for MRI of Cervical Spine**

**Date of Service: February 15, 2026**

Patient: [Your Name], Policy # [Your Policy Number]

Dear Appeals Review Committee:

I am writing to formally appeal the denial of the above-referenced claim for a cervical spine MRI performed on February 15, 2026, at Advanced Imaging Center.

**The Denial:** Your Explanation of Benefits dated March 1, 2026, states that "this diagnostic imaging is not medically necessary based on our clinical criteria."

**Medical Necessity Evidence:** My treating physician, Dr. Michael Chen, a board-certified neurologist, provides a letter dated March 10, 2026, stating that the MRI was essential to diagnose the cause of my persistent neck pain, numbness in my right arm, and headaches that have not responded to 8 weeks of conservative treatment including physical therapy, NSAIDs, and muscle relaxants.

Dr. Chen's assessment is supported by the American College of Radiology (ACR) Appropriateness Criteria, which rates cervical spine MRI as "Usually Appropriate" (score 8/9) for patients with persistent cervical radiculopathy lasting more than 6 weeks despite conservative care.

**Clinical Documentation:** My medical records demonstrate:

**Policy Compliance:** Section 4.2.1 of my policy states that diagnostic imaging is covered when ordered by a participating provider for conditions that have failed conservative treatment measures.

Supporting Documentation Attached:

I respectfully request that you overturn this denial and approve payment of $1,250 for the MRI service within 30 days of this letter. If I do not receive a favorable determination by [30 days from date], I will request an external review through the [State] Independent Review Organization as permitted under [State Insurance Code Section XXX].

Thank you for your attention to this urgent medical matter.

Sincerely,

[Your Name]

**Re: Appeal of Denied Claim #PT-2026-005678 for Physical Therapy Services**

**Date of Service: March 1-15, 2026**

Patient: [Your Name], Policy # [Your Policy Number]

Dear Sir or Madam:

I am appealing the denial of physical therapy services provided from March 1-15, 2026, at Summit Physical Therapy.

**The Denial:** Your letter dated March 20, 2026, states that "these services are excluded as treatment for a pre-existing condition per policy section 3.1."

**Counterargument:** My policy defines pre-existing conditions as those for which I received treatment in the 6 months prior to my coverage effective date of September 1, 2025. My medical records show no treatment for knee osteoarthritis prior to February 2026, when acute symptoms began following a fall.

**Medical Evidence:** My orthopedic surgeon, Dr. Lisa Rodriguez, states in her letter dated March 25, 2026, that this is a new acute injury (right knee meniscus tear) superimposed on underlying osteoarthritis. The physical therapy was necessary to restore function and prevent further deterioration.

This distinction between chronic pre-existing conditions and new acute injuries is supported by [State] insurance regulations, which state that pre-existing condition exclusions apply only to conditions that manifested symptoms requiring treatment prior to coverage.

Clinical Documentation:

**Policy Language:** Section 3.1 excludes "pre-existing conditions," defined as "conditions for which you received treatment during the 6 months before your coverage began." My injury occurred 6 months after coverage began.

Supporting Documentation Attached:

I request approval of $8,900 for the physical therapy services within 30 days. If denied, I will pursue external review under [State] law.

Sincerely,

[Your Name]

**Re: Appeal of Denied Claim #AUTO-2026-009876 for Rental Reimbursement**

**Date of Loss: April 5, 2026**

Policy # [Your Policy Number]

Dear Claims Appeals Specialist:

I am appealing the denial of rental car reimbursement for 7 days during repair of my vehicle following a covered collision on April 5, 2026.

**The Denial:** Your adjuster stated that "rental reimbursement is not covered under your policy."

**Policy Coverage:** Section 8.1 of my policy provides that "we will pay for a rental car not to exceed [daily limit] per day for up to [number] days when your vehicle is being repaired due to a covered claim."

My vehicle was totaled in a covered at-fault accident and required 7 days for repair/replacement. I rented a vehicle at the recommended body shop rate of $45/day.

Supporting Documentation:

I request approval of $315 for the rental car reimbursement within 14 days.

Sincerely,

**Re: Appeal of Denied Life Insurance Claim #LIFE-2026-012345**

**Insured: [Deceased Name], Policy # [Policy Number]**

Date of Death: May 10, 2026

Dear Claims Director:

As beneficiary of the above-referenced life insurance policy, I am appealing the denial of the $100,000 death benefit claim.

**The Denial:** Your letter dated May 25, 2026, states that "the claim is denied due to suicide within the 2-year contestability period per policy section 5.2."

**Factual Correction:** The death was accidental, not suicidal. The coroner's report and police investigation confirm accidental overdose during legitimate pain management for terminal cancer.

**Medical Evidence:** The insured had stage IV pancreatic cancer with severe pain managed by prescribed opioids. The overdose was accidental due to improper dosing during a pain crisis, not intentional self-harm.

Supporting Documentation:

**Policy Language:** Section 5.2 excludes suicide but does not exclude accidental death. The contestability period applies to material misrepresentations, not accidental deaths.

I request approval of the $100,000 death benefit within 30 days.

Sincerely,

[Beneficiary Name]

**Re: Appeal of Denied Claim #DENT-2026-015678 for Dental Implant**

**Date of Service: June 1, 2026**

Policy # [Your Policy Number]

Dear Appeals Committee:

I am appealing the denial of coverage for a dental implant placed on June 1, 2026, by Dr. Robert Kim.

**The Denial:** Your EOB states that "dental implants are considered cosmetic and not covered."

**Medical Necessity:** The implant was required to replace a tooth lost due to severe periodontal disease, not for cosmetic purposes. My periodontist, Dr. Sarah Wong, states that failure to replace the tooth would lead to further bone loss, adjacent tooth migration, and potential bite collapse.

Clinical Evidence:

**Policy Coverage:** Section 2.3 covers "restorative procedures required to maintain dental health" and "prevent further dental disease."

Supporting Documentation:

I request approval of $2,800 for the implant within 30 days.

Sincerely,

[Your Name]
