Unspecified superficial injury of left ankle, init encntr

This code signifies a non-specific, minor injury affecting the outermost layers of the skin and subcutaneous tissue of the left ankle. It indicates that the precise nature of the superficial injury (e.g., abrasion, contusion, blister) is not documented or determined at the time of the initial encounter.

This code is appropriate when a patient presents with a left ankle injury that is clearly superficial, but the physician's documentation lacks the specificity to assign a more detailed code for an abrasion, contusion, or blister. It is used for the initial treatment or evaluation of such an injury.

• Only use this code when documentation does not specify the type of superficial injury.
• Always strive for a more specific code if the documentation allows (e.g., S90.022A for contusion of left ankle).
• Ensure the "A" seventh character is appended for the initial encounter for active treatment.
