M96.4 — Postsurgical lordosis
M96.4 is a billable, specific ICD-10-CM code for postsurgical lordosis. It is valid for submission on a claim.
Excludes2 inherited from the categories above M96.4
Also inherited, and the opposite of Excludes1: these conditions are not part of M96.4, but a patient can have both, so you may code both.
Written on M96 — Intraoperative and postprocedural complications and disorders of musculoskeletal system, not elsewhere classified
Other codes that can never be billed with M96.4
These codes carry an Excludes1 note pointing at M96.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M96.4 alone.
- M40Kyphosis and lordosis
Risk adjustment
M96.4 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.
Medicare coverage
M96.4 is named in 17 Medicare coverage policies — 10 listing it as supporting medical necessity, and 7 listing it as NOT covered. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How M96.4 is indexed
