Questions About M54.10Overview

What is the ICD-10 code for radiculopathy, site unspecified?

The ICD-10-CM code for radiculopathy, site unspecified is M54.10 (sometimes written as M5410). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is M54.10 (Radiculopathy) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report radiculopathy, site unspecified on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Can M54.10 be reported with M79.2?

Not as a rule. The Excludes1 note at M54.1, which applies to M54.10, lists "neuralgia and neuritis NOS (M79.2)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

What is the ICD-9 equivalent of M54.10?
