M93Other osteochondropathies

Non-billable headerICD-10-CM

M93 is a non-billable header ICD-10-CM code for other osteochondropathies. 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.

  • osteochondrosis of spine (M42.-)

Other codes that can never be billed with M93

These codes carry an Excludes1 note pointing at M93. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M93 alone.

  • M23Internal derangement of knee
  • M87Osteonecrosis
  • M91Juvenile osteochondrosis of hip and pelvis
  • S72.13Apophyseal fracture of femur
  • S79.0Physeal fracture of upper end of femur
  • S79.01Salter-Harris Type I physeal fracture of upper end of femur
  • S92.14Dome fracture of talus

Risk adjustment

M93 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 M93

5 child codes. Green means billable.
