Utilization Review Checklist
Radial Nerve Entrapment
Derived from the ACOEM Elbow Disorders Guideline, edition 14 July 2025, as adopted into the California MTUS 2 January 2026. CPT 24495, 64708, 64712. ICD-10 G56.3.
Draft — not reviewed or approved by COA. Prepared by Rette from the ACOEM guideline named above. This is not a COA document and does not reproduce COA’s own checklists.
CriteriaCheck if documented
Presumptive Diagnosis
Required
Pain and tenderness in the proximal lateral forearm, distal to the lateral epicondyle
“A presumptive diagnosis requires pain and tenderness in the proximal lateral forearm, distal to the lateral epicondyle which may or may not be accompanied by paresthesias depending on the location of the neurological compression.” — p. 156
Confirmatory Diagnosis
Any one of the following
Confirmatory electrodiagnostic testing consistent with radial neuropathy, generally including segmental analysis
“● confirmatory electrodiagnostic testing interpreted as consistent with radial neuropathy that generally includes segmental analysis, aka “inching technique; or” — p. 156
OR
Injection into the radial tunnel with near or total resolution of pain with the anaesthetic
“● injection into the radial tunnel along the nerve with near/total resolution of pain with the anesthetic, and/or” — p. 156
OR
Wrist and/or digital extensor muscle weakness and/or atrophy
“● wrist and/or digital extensor muscles weakness and/or atrophy.” — p. 156
Conservative Care
Required
Non-operative treatment including elbow and wrist splinting
“Non-operative treatments include: ● elbow and wrist splinting.” — p. 156
Surgical Considerations (surgical release)
Required
Severe symptoms and signs, or lack of improvement after nonoperative treatment trialed for at least 3 months
“Surgical considerations include either: ● severe symptoms and signs (e.g., severe electrodiagnostic findings, continuous paresthesias, extensor muscle atrophy) or ● lack of improvement or resolution following nonoperative treatment trialed for at least 3 months.” — p. 156
Any one of the following:
Severe symptoms and signs (e.g., severe electrodiagnostic findings, continuous paresthesias, extensor muscle atrophy)
“● severe symptoms and signs (e.g., severe electrodiagnostic findings, continuous paresthesias, extensor muscle atrophy) or” — p. 156
OR
Lack of improvement or resolution following nonoperative treatment trialed for at least 3 months — at least 3 months
“● lack of improvement or resolution following nonoperative treatment trialed for at least 3 months.” — p. 156
Procedures — the guideline treats each separately
Surgical release for subacute or chronic radial neuropathy
Recommended.
Strength of Evidence — Recommended, Insufficient Evidence (I)
The guideline offers two alternative routes to surgery: severe symptoms and signs, OR three months without improvement on non-operative treatment. A patient with extensor atrophy or severe electrodiagnostic findings does not have to wait out the three months. Note the Rationale is more cautious than the indication, asking for 3 to 6 months and unequivocal evidence, so a reviewer may quote the longer figure — document the electrodiagnostic findings and the objective loss of function.
