What the insurer actually argued

Denials fall into different categories, and they don’t succeed equally — so the reason on your letter changes how you should answer it.
Reason givenDecisionsOverturned
Medical Necessity
The plan said the care wasn’t medically necessary. The most common fight, and the most winnable.
35
82.9%
Experimental/Investigational
The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument.

Where the denial was overturned

Findings: The physician reviewer found that Nature of Statutory Criteria/Case Summary: A patient has requested authorization and coverage for Actemra. The American College of Rheumatology (ACR) guidelines for the treatment of rheumatoid arthritis specifically recommend that when patients have not responded adequately to one class of biologic therapy, such as tumor necrosis factor (TNF) inhibitors, switching to a different mechanism of action is conditionally recommended over continuing within the same class. In this case, the patient presents with seronegative rheumatoid arthritis and has failed multiple prior therapies, including two TNF inhibitors as well as conventional disease-modifying anti-rheumatic drugs. The ACR guidelines support the use of Actemra (tocilizumab) in this patient, which works through interleukin 6 receptor inhibition.

Findings: The physician reviewer found that Nature of Statutory Criteria/Case Summary: A patient has requested authorization and coverage for suprascapular and axillary nerve radiofrequency ablation. A systematic review indicates that radiofrequency-based interventions targeting shoulder innervation can reduce chronic shoulder pain and improve function. Randomized trial data further show that applying radiofrequency energy to the suprascapular nerve distribution can provide clinically meaningful analgesic benefits compared with injection-based approaches in chronic shoulder pain populations. Prospective evidence also shows meaningful improvements in pain and function in appropriately selected patients with low rates of serious complications over follow-up.

Where the denial was upheld

Worth reading too — these show what an appeal has to overcome.
Findings: The physician reviewer found that Nature of Statutory Criteria/Case Summary: A patient has requested authorization and coverage for Journavx. Suzetrigine (Journavx) is U.S. Food and Drug Administration (FDA)-approved for moderate-to-severe acute pain in adults, and the official prescribing information states that its use for acute pain has not been studied beyond 14 days. Therefore, for the indication being requested here, ongoing treatment of chronic ankle pain, chronic low back pain, and persistent shoulder/neck pain, continued use is not supported by the same level of evidence that underpins its FDA-approved, time-limited acute-pain indication. Evidence for chronic/peripheral neuropathic pain remains uncertain.
Experimental/Investigational · 2026 · IMR EI26-46834
Findings: The physician reviewer found that Nature of Statutory Criteria/Case Summary: A patient has requested authorization and coverage for implantation of the MISHA Knee System.Although some studies report improvement in pain and function with the MISHA Knee System and mid-term survivorship without conversion to arthroplasty, the current evidence base remains limited by nonrandomized study designs and lack of large comparative trials demonstrating superiority over established treatment pathways.
