Osteopathy after poliomyelitis, unspecified forearm

This code signifies a bone disorder that develops as a sequela of poliomyelitis, affecting an unspecified forearm. It describes a pathological change in bone structure or function resulting from the long-term effects of polio, without further specification of the type of osteopathy.

Apply this code when documentation clearly indicates a diagnosis of osteopathy in the forearm that is directly attributed to a history of poliomyelitis. This is used when the specific type of osteopathy (e.g., osteoporosis, osteomalacia) is not documented. Supporting documentation would include a history of polio and diagnostic findings (e.g., imaging reports) confirming bone pathology in the forearm.

• Ensure the medical record explicitly links the osteopathy to a prior poliomyelitis infection.
• If the specific type of osteopathy (e.g., osteoporosis) is documented, use a more specific code from the M80-M85 range, linked with a sequela code for poliomyelitis (B91).
• Always specify laterality (left or right) if documented; "unspecified" should only be used when laterality is truly unknown.
