Unsp superficial injury of unspecified knee, subs encntr

This code indicates a superficial injury to the knee, such as a bruise, abrasion, or minor contusion, where the specific nature of the injury and the exact location on the knee are not documented. The "D" seventh character signifies that this is a subsequent encounter for care of the injury, meaning the patient is receiving routine follow-up care during the healing phase.

This code is appropriate for follow-up visits when a patient is being seen for ongoing management or healing of a superficial knee injury that was not precisely specified in the initial encounter. It is used when the documentation lacks details about the exact type of superficial injury (e.g., contusion vs. abrasion) and the specific side of the knee affected.

• Only use the "D" seventh character for encounters after the active treatment phase, during the healing or recovery period.
• Avoid this code if the documentation specifies the exact nature of the superficial injury (e.g., contusion, abrasion) or the specific knee (right or left).
• If the encounter is for initial treatment of the injury, a code with the "A" seventh character should be used instead.
