Osteonecrosis due to drugs, unspecified hand

This code signifies the death of bone tissue in an unspecified hand, specifically caused by the use of certain medications. This condition, also known as avascular necrosis, results from a loss of blood supply to the bone, leading to bone collapse and potential joint destruction.

Apply this code when documentation clearly states osteonecrosis of the hand is attributed to drug therapy, but the specific hand (left or right) is not identified. This diagnosis is typically supported by imaging studies (e.g., X-ray, MRI) showing bone infarction and a patient history of medication use known to cause osteonecrosis (e.g., corticosteroids, bisphosphonates).

• Always strive for laterality (left or right hand) if documented; if specified, use the more precise M87.141 or M87.142.
• Do not use this code if the cause of osteonecrosis is not drug-induced; refer to other subcategories within M87.
• Code any associated pain or functional limitations separately, if applicable.
