Other deformities of toe(s) (acquired), right foot

This code signifies an acquired structural abnormality of one or more toes on the right foot, excluding hallux valgus (bunion), hallux rigidus, or hammer/mallet/claw toe deformities. These deformities are not congenital but develop over time due to various factors such as ill-fitting footwear, trauma, or underlying medical conditions.

Use this code for documented acquired deformities of the right foot toes that do not fit more specific codes like hammer toe or bunion. Clinical documentation should clearly specify the right foot and describe the nature of the toe deformity as acquired, often noting its impact on ambulation or footwear.

• Ensure documentation specifies "acquired" and "right foot" to support code assignment.
• Distinguish from congenital toe deformities (Q66.-) and more specific acquired deformities like hammer toe (M20.4-) or hallux valgus (M20.1-).
• Always code to the highest level of specificity; if a more precise code for the specific toe deformity exists, use that instead.
