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

This code signifies a non-congenital structural abnormality or malformation affecting one or more toes on the patient's left foot. These deformities can arise from various causes such as trauma, arthritis, ill-fitting footwear, or neuromuscular conditions, resulting in an altered shape or alignment of the toe(s). The specific type of deformity is not documented or is unknown.

This code is appropriate when documentation indicates an acquired deformity of the left foot's toe(s) without specifying the exact nature of the deformity (e.g., hammer toe, claw toe, mallet toe). It should be used when the provider's assessment confirms a deformity but lacks further detail regarding its specific morphology. Documentation should clearly state "acquired deformity of toe(s), left foot" or similar.

• Avoid using this code if the specific type of toe deformity (e.g., hammer toe, claw toe) is documented; instead, use the more specific code from the M20.1-M20.5 series.
• Ensure laterality is clearly documented as "left foot" to support this code. If the deformity is on the right foot, a different code applies.
• This code is for acquired deformities; congenital deformities of the toe(s) are coded from the Q66-Q79 series.
