Acquired deformities of toe(s), unsp, unspecified foot

This code signifies a non-congenital structural abnormality of one or more toes, where the specific type of deformity is not documented. It indicates a general acquired malformation of the toe(s) on an unspecified foot.

Use this code when the medical record clearly states an acquired toe deformity but lacks specific details regarding the type (e.g., hammer toe, claw toe, mallet toe) or the affected foot (left or right). Documentation supporting this code would include physician notes mentioning "acquired toe deformity" without further specification.

• Avoid using this code if the specific type of toe deformity (e.g., hammer toe) is documented; instead, use a more specific code from the M20.1-M20.5 series.
• Do not use this code if the laterality (left or right foot) is specified; look for codes with a 1 or 2 in the 6th character.
• This code should be used when the documentation is truly unspecified regarding both the type of deformity and the affected foot.
