M89.661
ICD-10-CMThis code describes a bone disorder, specifically osteopathy, that develops in the right lower leg as a long-term complication or sequela of poliomyelitis. It indicates a pathological change in bone structure or function attributable to the prior polio infection, affecting the tibia, fibula, or ankle region.
Use this code when documentation clearly links osteopathic changes in the right lower leg to a history of poliomyelitis. This typically applies to patients presenting with chronic bone pain, deformity, or functional impairment in the affected limb, where the etiology is determined to be post-polio syndrome or a direct sequela of the initial infection. Supporting documentation would include a confirmed history of poliomyelitis and diagnostic imaging or clinical findings consistent with osteopathy.
