Medial subluxation of proximal end of tibia, unsp knee, subs

This code describes a partial dislocation of the inner (medial) aspect of the upper part of the shin bone (tibia) at the knee joint. This injury implies the joint surfaces are still in partial contact, but not fully aligned. The "unspecified knee" indicates that the laterality (left or right) of the injury is not documented.

Use this code for follow-up encounters for a patient diagnosed with a medial subluxation of the proximal tibia where the specific knee (left or right) is not recorded in the medical documentation. This includes routine follow-up visits, cast changes, or medication refills during the healing phase.

• Ensure the documentation clearly states "subsequent encounter" for this specific injury.
• If laterality (left or right knee) is documented, a more specific code should be used.
• Do not use this code for the initial treatment of the injury; an "initial encounter" code would be appropriate then.
