Questions About M25.30Overview

What is the ICD-10 code for other instability, unspecified joint?

The ICD-10-CM code for other instability, unspecified joint is M25.30 (sometimes written as M2530). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is M25.30 (Other instability of joint) a billable code?

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

What MS-DRG does M25.30 group to?

When other instability, unspecified joint is the principal diagnosis on an inpatient stay, it groups to MS-DRG 564, 566, 565, with relative weights from 0.7374 to 1.4909 depending on complications. Higher weights mean higher Medicare reimbursement.

Can M25.30 be reported with a code from M24.2?

Not as a rule. The Excludes1 note at M25.3, which applies to M25.30, lists "instability of joint secondary to old ligament injury (M24.2-)". 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 M25.30?

Under the General Equivalence Mappings, other instability, unspecified joint converts to ICD-9-CM 718.80 (jt derangmnt NEC-unsp jt). The mapping is approximate, so confirm the match fits the documentation.
