Infect/inflm reaction due to int fix of left femur, sequela

This code signifies a persistent or late-occurring infection or inflammatory response stemming from an internal fixation device previously implanted in the left femur. It indicates that the acute phase of the infection or inflammation has passed, but its effects or complications are still present.

Apply this code when documenting long-term consequences, such as chronic osteomyelitis, non-union, or persistent pain, directly attributable to an infected or inflamed internal fixation device in the left femur. This is appropriate for follow-up encounters after the initial treatment of the acute infection or inflammation.

• Requires a seventh character 'S' to indicate sequela, meaning the residual effect of a past condition.
• Do not use for acute infections or inflammatory reactions; those would use the appropriate acute T84.621A or T84.621D codes.
• Always code the specific manifestation of the sequela (e.g., chronic osteomyelitis) as a primary diagnosis, with this code as a secondary diagnosis to identify the cause.
