ICD-10 Code for Osteonecrosis

The ICD-10-CM code for osteonecrosis is M87.9 — Osteonecrosis, unspecified. This is the code the Alphabetic Index gives for osteonecrosis with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).

BillableUnspecified

M87.9 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.

Which osteonecrosis code should you use?

The Alphabetic Index lists 72 codes under Osteonecrosis. Which one applies depends on the qualifier documented in the record — the type, site, cause, or associated condition. Find the qualifier below, then verify the code in the Tabular List before using it.
