Questions About M62.84Overview

What is the ICD-10 code for sarcopenia?

The ICD-10-CM code for sarcopenia is M62.84 (sometimes written as M6284). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is M62.84 (Other specified disorders of muscle) a billable code?

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

What MS-DRG does M62.84 group to?

When sarcopenia is the principal diagnosis on an inpatient stay, it groups to MS-DRG 557, 558, with relative weights from 0.8873 to 1.4883 depending on complications. Higher weights mean higher Medicare reimbursement.

Can M62.84 be reported with G72.1?

Not as a rule. The Excludes1 note at M62, which applies to M62.84, lists "alcoholic myopathy (G72.1)". 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 coded first with M62.84?

The Code First note reads: underlying disease, if applicable, such as: disorders of myoneural junction and muscle disease in diseases classified elsewhere (G73.-); other and unspecified myopathies (G72.-); primary disorders of muscles (G71.-). When one of these applies, it is sequenced before M62.84.
