Calcifcn and ossifictn of muscles assoc w burns, r up arm

This code signifies the pathological hardening of muscle tissue in the right upper arm due to the deposition of calcium salts (calcification) and/or bone formation (ossification) following a burn injury. This condition, known as heterotopic ossification, results in restricted movement and pain in the affected limb.

Apply this code when documentation explicitly states calcification or ossification of muscles in the right upper arm as a sequela of a burn. The physician's notes should confirm the presence of these deposits within the muscle tissue and link them directly to a previous burn injury in that specific anatomical location.

• Ensure the documentation specifies "right upper arm" to justify laterality and anatomical site.
• Do not use this code for calcification or ossification not explicitly linked to a burn injury; consider other M61 subcategories.
• Sequence this code after the burn code (T20-T32) if the burn is still active, or as a primary diagnosis if the sequela is the focus of the encounter.
