External constriction, unsp lesser toe(s), init encntr

This code signifies a condition where an external object or material is causing a constricting effect on one or more of the smaller toes (second through fifth toes), leading to potential circulatory compromise or tissue damage. The specific toe affected is not documented, and this code is used for the initial presentation of this injury.

Apply this code when a patient presents with a constriction injury to an unspecified lesser toe, such as from a tight shoe, a ring, or a piece of string, and it is the first time this particular injury is being treated. This code is appropriate when the exact toe (e.g., second, third, fourth, or fifth) is not specified in the clinical documentation.

• Ensure documentation clearly states "initial encounter" for this specific injury.
• If the specific lesser toe is identified (e.g., second toe), use a more precise code from the S90.44- series.
• Do not use this code if the constriction is on the great toe; a different code series applies for the great toe.
