What cannot be coded together with M60.23?

M60.23

M60.23 — Foreign body granuloma of soft tissue, not elsewhere classified, forearm

Non-billable headerICD-10-CM

M60.23 is a non-billable header ICD-10-CM code for foreign body granuloma of soft tissue, not elsewhere classified, forearm. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 inherited from the categories above M60.23

These are not written on M60.23, but they bind it: a note on a category applies to every code beneath it. Billing M60.23 with anything listed here is a denial.

Written on M60.2 — Foreign body granuloma of soft tissue, not elsewhere classified

foreign body granuloma of skin and subcutaneous tissue (L92.3)

Excludes2 inherited from the categories above M60.23

Also inherited, and the opposite of Excludes1: these conditions are not part of M60.23, but a patient can have both, so you may code both.

Written on M60 — Myositis

inclusion body myositis [IBM] (G72.41)

Other codes that can never be billed with M60.23

These codes carry an Excludes1 note pointing at M60.23. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M60.23 alone.

G72Other and unspecified myopathies
M79.1Myalgia

Risk adjustment

M60.23 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code history

M60.23 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead M60.23
