Sprain of interphalangeal joint of unsp lesser toe(s), init

This code signifies a sprain, or ligamentous injury, to the joint between the phalanges of any lesser toe (the second through fifth toes) where the specific toe involved is not documented. It indicates the initial presentation or active treatment phase of such an injury.

Apply this code when a patient presents with a sprain of an interphalangeal joint of a lesser toe, and the medical record does not specify which particular lesser toe is affected. This is appropriate for the initial evaluation and management of the injury, including diagnostic workup and initial treatment plan.

• Ensure documentation clearly states "unspecified lesser toe" or lacks specificity regarding the affected lesser toe.
• Confirm this is the patient's first encounter for this specific injury; subsequent encounters will require a different seventh character.
• Do not use if the sprain is of the great toe or if the specific lesser toe (e.g., second, third) is identified.
