The conditions below are not part of M84.551, but a patient may have both at the same time. When documentation supports it, M84.551 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 M84.551 is sequenced first depends on the reason for the encounter.
