Osteopathy after poliomyelitis, unspecified lower leg

This code describes a bone disorder or disease (osteopathy) that develops as a long-term complication or sequela of a prior poliomyelitis infection, affecting an unspecified lower leg. It indicates a pathological change in bone structure or function attributable to the effects of polio, rather than an acute injury or other primary bone disease.

Use this code for patients presenting with documented osteopathic changes in the lower leg, where the medical record clearly links these changes to a history of poliomyelitis. This typically applies to chronic conditions manifesting years after the initial polio infection. Documentation should specify the lower leg as the affected site, but without further detail on laterality.

• Ensure documentation explicitly states "osteopathy after poliomyelitis" or similar phrasing linking the bone condition to polio.
• Avoid using this code for acute fractures or other bone conditions not directly attributed to the sequelae of poliomyelitis.
• If laterality (right or left lower leg) is specified in the documentation, a more specific code from the M89.66- subcategory should be used.
