Lateral sublux of proximal end of tibia, unsp knee, sequela

This code signifies a chronic or residual condition resulting from a previous lateral subluxation of the proximal tibia, where the lower leg bone has partially dislocated outwards from the knee joint. It indicates that the initial injury has healed, but there are lasting effects or complications that require ongoing management or documentation. The "unspecified knee" denotes that the laterality (left or right) is not specified in the medical record.

Apply this code when documenting a patient presenting with long-term issues, such as chronic pain, instability, limited range of motion, or functional impairment, directly attributable to a past lateral subluxation of the proximal tibia. This code is appropriate for follow-up encounters after the initial injury has been treated and the patient is experiencing persistent sequelae.

• Always ensure documentation clearly links the current condition to a previous lateral subluxation of the proximal tibia.
• Look for terms like "history of," "residual effects of," "chronic instability due to," or "pain secondary to old injury" in the medical record.
• If the laterality of the knee is specified (left or right), a more specific code from the S83.14- series should be used instead.
