Excludes2 — not included here — inherited from M84
The conditions below are not part of M84.562K, but a patient may have both at the same time. When documentation supports it, M84.562K and the excluded code may both be reported.
- traumatic fracture of bone-see fracture, by site
Code also — inherited from M84.5
Two codes may be needed to describe the condition fully. Whether M84.562K is sequenced first depends on the reason for the encounter.

How long has M84.562K existed?
M84.562K has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
