Posterior sublux of proximal end of tibia, unsp knee, subs

This code describes a partial dislocation of the upper part of the shin bone, where it has shifted backward relative to the thigh bone, affecting an unspecified knee. This indicates that the initial injury has already been treated, and the patient is now receiving follow-up care, such as cast changes, physical therapy, or medication adjustments.

Use this code for subsequent encounters when a patient is being treated for a posterior subluxation of the proximal tibia in an unspecified knee. This applies to situations where the patient is in the healing phase and receiving ongoing care for the injury, but not for the initial acute treatment.

• Ensure the documentation clearly states "subsequent encounter" for this specific injury.
• Verify that the laterality (left or right knee) is not specified in the medical record; if it is, a more specific code should be used.
• This code is appropriate for routine follow-up care, including cast removal, wound care, or physical therapy sessions related to the subluxation.
