Posterior disloc of proximal end of tibia, r knee, sequela

This code signifies a chronic or late-effect condition resulting from a posterior dislocation of the upper part of the tibia in the right knee. It indicates that the initial injury has resolved, but the patient continues to experience residual problems, symptoms, or complications directly attributable to that past dislocation.

Use this code when documenting a patient presenting with ongoing pain, instability, limited range of motion, or other long-term sequelae in the right knee, where a previously treated posterior tibial dislocation is the established cause. This applies to follow-up encounters for complications that arise after the acute phase of the original injury has passed.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, instability).
• Ensure documentation clearly links the current condition to the prior posterior tibial dislocation of the right knee.
• Do not use this code for acute or initial treatment of the dislocation; it is exclusively for late effects.
