In 51 published external-review decisions involving muscle spasms, independent physician reviewers overturned the insurer’s denial 45.1% of the time.

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 given | Decisions | Overturned |
|---|---|---|
Medical Necessity The plan said the care wasn’t medically necessary. The most common fight, and the most winnable. | 31 | 38.7% |
Experimental/Investigational The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument. | 20 | 55% |

What the reviewers wrote
Excerpts from the independent reviewers’ published findings — the actual reasoning, quoted, not summarised.
Where the denial was overturned
Nature of Statutory Criteria/Case Summary: The patient has requested reimbursement and prospective authorization and coverage for Fentanyl transdermal system, 100 mcg, 15 patches per month (Please note: ten patches per month have been approved by the Health Plan.). On determining when to initiate or continue opioids for chronic pain, Dowell and colleagues report, “Nonpharmacologic therapy and nonopioid pharmacologic therapy are preferred for chronic pain. Clinicians should consider opioid therapy only if expected benefits for both pain and function are anticipated to outweigh risks to the patient.
Findings: The physician reviewer found that Nature of Statutory Criteria/Case Summary: An enrollee has requested authorization and coverage for RT300 functional electrical stimulation (FES) system. One study evaluated the effects of FES and therapeutic exercises on trunk muscle tone and dynamic sitting balance in patients with chronic spinal cord injury via a crossover trial. The authors found that FES resulted in an increased muscle oscillation frequency of more than 6% and increased limits of stability of trunk flexion by 30% in spinal cord injury patients who also received FES in addition to therapeutic exercises alone. Based on their findings, the authors concluded that a six-week home therapy program incorporating FES increased trunk muscle tone and dynamic sitting balance in flexion more than therapeutic exercise alone.
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: The patient has requested reimbursement for bilateral breast reduction surgery. The American Society of Plastic Surgeons (ASPS) guidelines state that reduction mammaplasty should be performed based on documentation of the severity of the symptoms of macromastia and its impact on health-related quality of life. The ASPS guidelines indicate that reduction mammaplasty may be indicated if at least two of the following quality-of-life signs are present: chronic breast pain due to breast weight, intertrigo unresponsive to medical management, upper back, neck, and shoulder pain, backache, thoracic kyphosis, shoulder grooving from bra straps, upper extremity paresthesia due to brachial plexus compression syndrome secondary to the weight of the breasts being transferred to the shoulder strap area, headache, and…
Nature of Statutory Criteria/Case Summary: An enrollee has requested authorization and coverage for RT300 Functional Electrical Stimulating (FES) Therapy System.Findings: Two out of three physician reviewers found that RT300 Functional Electrical Stimulating (FES) Therapy System is not likely to be more beneficial for the enrollee than any available standard therapy.The RT300 FES Therapy System provides passive exercise in individuals with neurological weakness by using topical electrical stimulation leads to activate paralyzed limb muscles to drive a stationary cycle. The data from the medical literature, however, has not demonstrated that use of this device improves function or health outcomes in a clinically significant manner for persons with spinal cord pathology.
Figures and quotations on this page come from 42,749 published decisions in the California DMHC Independent Medical Review dataset. These are California outcomes — every state runs an equivalent external review, but the rates here are California’s. Excerpts are quoted verbatim from the public record and describe this condition generally, not any individual case.
How to use this in your appeal
These outcomes come from California’s external review program — an independent physician panel whose decision binds the insurer. Every state has an equivalent, and internal appeals succeed even more often. If your care for muscle spasms was denied, the published record says the denial is worth fighting.
