Is M96 a billable ICD-10-CM code?

No. M96 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does M96 sit in the tabular list?

Diseases of the musculoskeletal system and connective tissue (M00-M99), in the block Intraoperative and postprocedural complications and disorders of musculoskeletal system, not elsewhere classified (M96).

M96

M96 — Intraoperative and postprocedural complications and disorders of musculoskeletal system, not elsewhere classified

Non-billable headerICD-10-CM

M96 is a non-billable header ICD-10-CM code for intraoperative and postprocedural complications and disorders of musculoskeletal system, not elsewhere classified. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

arthropathy following intestinal bypass (M02.0-)
complications of internal orthopedic prosthetic devices, implants and grafts (T84.-)
disorders associated with osteoporosis (M80)
periprosthetic fracture around internal prosthetic joint (M97.-)
presence of functional implants and other devices (Z96-Z97)

Other codes that can never be billed with M96

These codes carry an Excludes1 note pointing at M96. 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 alone.

M25.3Other instability of joint
M40Kyphosis and lordosis
M96.81Intraoperative hemorrhage and hematoma of a musculoskeletal structure complicating a procedure

Risk adjustment

M96 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 to one of these instead M96

9 child codes. Green means billable.
