Mech compl of oth bone devices, implants and grafts, sequela

This code signifies a long-term or residual issue stemming from a mechanical problem with a bone-related device, implant, or graft that is not specifically classified elsewhere. It indicates that the initial mechanical complication has resolved, but its lasting effects are still present and require ongoing management.

Use this code when documenting a patient presenting with a chronic condition or permanent impairment directly attributable to a past mechanical complication of a bone device, implant, or graft. This applies when the acute phase of the mechanical complication has passed, and the current encounter addresses the sequelae. Examples include chronic pain, limited range of motion, or persistent instability resulting from a prior hardware failure, displacement, or fracture of an implant.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, nonunion).
• Ensure documentation clearly links the current condition to a past mechanical complication of a bone device, implant, or graft.
• Do not use for active or acute mechanical complications; those require codes from the T84.3- series without the "S" seventh character.
