Sprain of unsp cruciate ligament of left knee, subs encntr

This code indicates a sprain of an unspecified cruciate ligament in the left knee that is being treated during a follow-up visit after the initial injury. It signifies an injury to either the anterior or posterior cruciate ligament, but the specific ligament involved was not documented or determined. The patient is no longer in the acute phase of treatment.

Use this code for subsequent encounters when a patient presents for ongoing care, physical therapy, or follow-up appointments related to a previously diagnosed, but unspecified, cruciate ligament sprain of the left knee. This applies when the specific cruciate ligament (ACL or PCL) was not identified in the initial diagnosis or subsequent documentation.

• Ensure documentation clearly states "left knee" and "unspecified cruciate ligament sprain."
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use this code for initial encounters or for sequelae (late effects) of the injury.
