Posterior subluxation of left ulnohumeral joint, sequela

This code indicates a partial dislocation of the elbow joint, specifically where the ulna and humerus meet, that has occurred on the posterior aspect of the joint. The "sequela" designation signifies that this subluxation is a late effect or complication of an earlier injury or condition, rather than an acute event.

Use this code when documenting a patient presenting with ongoing symptoms or complications directly attributable to a past posterior subluxation of the left ulnohumeral joint. This would include chronic pain, instability, or limited range of motion resulting from the previous injury. It is appropriate when the initial injury has resolved, but its long-term effects are being treated.

• Always ensure documentation clearly links the current condition to a prior injury of the left ulnohumeral joint.
• Do not use this code for acute or initial subluxations; those require codes from the acute injury section.
• Verify laterality (left) and the specific joint (ulnohumeral) and direction (posterior) are explicitly stated in the medical record.
