Infect/inflm reaction due to int fix of right ulna, sequela

This code signifies a chronic or residual infection or inflammatory response affecting the right ulna, specifically caused by an internal fixation device previously implanted in that bone. It indicates that the acute phase of the infection or inflammation has passed, but the patient continues to experience lingering effects directly attributable to the device.

Use this code when documenting a patient presenting with persistent symptoms such as chronic pain, swelling, drainage, or functional impairment in the right ulna, where these issues are determined to be a long-term consequence of an infection or inflammatory reaction related to an internal fixation device. This applies even if the device has since been removed, as long as the sequela is still present.

• Always ensure documentation clearly links the current sequela to a past infection/inflammation caused by the internal fixation device.
• Do not use this code for acute infections or inflammatory reactions; those require different codes.
• Verify the laterality (right ulna) is accurately documented in the patient's medical record.
