Is M02.04 a billable ICD-10-CM code?

No. M02.04 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does M02.04 sit in the tabular list?

Diseases of the musculoskeletal system and connective tissue (M00-M99), in the block Infectious arthropathies (M00-M02).

What cannot be coded together with M02.04?

M02.04 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above M02.04 (M02) and apply to it just the same.

Arthropathy following intestinal bypass, metacarpals and phalanges

Excludes1 inherited from the categories above M02.04

These are not written on M02.04, but they bind it: a note on a category applies to every code beneath it. Billing M02.04 with anything listed here is a denial.

Written on M02 — Postinfective and reactive arthropathies

Behçet's disease (M35.2)
direct infections of joint in infectious and parasitic diseases classified elsewhere (M01.-)
postmeningococcal arthritis (A39.84)
mumps arthritis (B26.85)
rubella arthritis (B06.82)
syphilis arthritis (late) (A52.77)
rheumatic fever (I00)
tabetic arthropathy [Charcôt's] (A52.16)

Other codes that can never be billed with M02.04

These codes carry an Excludes1 note pointing at M02.04. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M02.04 alone.

M01Direct infections of joint in infectious and parasitic diseases classified elsewhere

Risk adjustment

M02.04 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

M02.04 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 M02.04
