Adhesive Capsulitis: when insurers say no, reviewers often say yes
In 17 published external-review decisions involving adhesive capsulitis, independent physician reviewers overturned the insurer’s denial 23.5% 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. | 13 | 23.1% |
Experimental/Investigational The plan called the treatment unproven. These turn on published evidence, so the appeal is a literature argument. | 4 | 25% |

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 authorization and coverage for shoulder surgery. According to one study, rotator cuff tear is the most common shoulder pathology. The authors noted that systematic rehabilitation is the mainstay treatment for partial thickness cuff tears and is also acceptable for the initial management of full thickness cuff tears. Rehabilitation in cuff tear consists of strengthening the core stabilizers along with the rotator cuff and deltoid muscles. The authors reported that indications for the repair of a full thickness cuff tear include failed rehabilitation for three months, acute traumatic tear, younger age, intractable pain, and good-quality muscle.
A 45-year-old female enrollee has requested pulsed radiofrequency denervation of the left suprascapular nerve for treatment of her chronic pain, left shoulder, and adhesive capsulitis, left shoulder. Findings: Two physician reviewers found that the patient failed to receive benefit with minimally invasive surgery. A more invasive surgery is not appropriate for treatment of chronic pain unless there is an involved mechanical disruption. The next logical step after failed conservative therapy would be pulsed radiofrequency denervation of the left suprascapular nerve for long-term improvement of the patient’s shoulder pain.
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 authorization and coverage for surgical arthroscopy of the left shoulder with decompression and rotator cuff repair and coracoacromial ligament release for shoulder. Researchers explain, “Rotator cuff tear progression can be difficult to predict. Factors associated with tear enlargement include increasing symptoms, advanced age, involvement of two or more tendons, and rotator cable lesion. Nonsurgical treatment can be effective for patients with full-thickness tears.
Nature of Statutory Criteria/Case Summary: The patient has requested authorization and coverage for arthroscopy, left shoulder with coracoacromial ligament release (CPT 29826). In a randomized prospective trial with two-year follow-up, Abrams and colleagues concluded that there was no difference in clinical outcomes after rotator cuff repair with or without acromioplasty at two years postoperatively. Familiari and colleagues reported that, “A systematic review of the literature does not support the routine use of partial acromioplasty or coracoacromial ligament release in the surgical treatment of rotator cuff disease. In some instances, partial acromioplasty and release of the coracoacromial ligament can result in anterior escape and worsening symptoms.
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 adhesive capsulitis was denied, the published record says the denial is worth fighting.
