Sequelae of tuberculosis of bones and joints

This code indicates a residual condition or late effect resulting from a past tuberculosis infection that specifically affected bones and/or joints. These sequelae are the long-term consequences of the original active disease, which has since resolved. Examples include chronic osteomyelitis, joint deformities, or limited range of motion directly attributable to a prior skeletal tuberculosis.

Assign this code when documentation clearly states a patient is experiencing a current condition that is a direct, lasting consequence of a previously treated or resolved tuberculosis of the bones or joints. This code is appropriate when the active tuberculosis infection is no longer present. Supporting documentation should specify the link between the current condition and the prior skeletal TB.

• Always sequence this code after the code identifying the specific sequela (e.g., M86.6x for chronic osteomyelitis).
• Do not use this code if the tuberculosis of the bones and joints is still active; instead, use codes from category A18.0.
• Ensure documentation explicitly states the condition is a "sequela," "late effect," or "due to prior" tuberculosis of bones/joints.
