Unspecified acquired deformity of hand, unspecified hand

This code signifies an acquired structural abnormality of the hand that is not congenital and for which the specific nature of the deformity is not documented. It indicates a deviation from the normal anatomical form or position of the hand, without further detail regarding the type of deformity (e.g., clubbing, contracture, malunion).

Use this code when the medical record clearly states an acquired hand deformity but lacks specific information about its type or laterality. This is appropriate when documentation only mentions "acquired hand deformity" without further elaboration, or when the provider is unable to determine the exact nature of the deformity at the time of coding.

• Avoid using this code if more specific documentation is available regarding the type of hand deformity (e.g., M20.0- for mallet finger, M20.1- for other acquired finger deformities).
• Query the provider for more specific details if possible, as a more precise code will improve data accuracy and potentially impact reimbursement.
• This code should only be used when laterality (left or right hand) is also unspecified in the medical record.
