Mech compl of int fix of bones of hand and fingers, sequela

This code signifies a long-term or residual issue arising from a previous mechanical complication involving an internal fixation device in the bones of the hand or fingers. This could include problems like loosening, displacement, or fracture of the device itself, occurring after the initial acute phase of the complication has passed. The "sequela" designation indicates that the current condition is a late effect of that prior mechanical problem.

Use this code when documenting a patient presenting with ongoing symptoms or conditions directly attributable to a past mechanical failure of an internal fixation device in the hand or fingers. This applies to situations where the original complication has been addressed, but its lasting impact is still present and requires ongoing management or evaluation. Examples include chronic pain, limited range of motion, or nerve impingement resulting from a previously displaced or broken plate or screw.

• 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 previous mechanical complication of the internal fixation device.
• Do not use this code for acute or current mechanical complications; those require codes without the "S" seventh character.
