Lateral dislocation of left ulnohumeral joint, init encntr

This diagnosis code signifies a displacement of the ulna and humerus bones at the elbow joint, specifically to the outer side of the joint, affecting the patient's left arm. This injury disrupts the normal articulation of the elbow, often resulting in significant pain and limited range of motion.

This code is appropriate for documenting the initial treatment of a patient presenting with a newly diagnosed lateral dislocation of the left elbow. It should be used when the patient is receiving active treatment for the injury, such as reduction, immobilization, or surgical repair.

• Ensure documentation clearly specifies "lateral" and "left" to support this precise code.
• Verify this is the patient's first encounter for this specific injury; subsequent encounters will require a different seventh character.
• Distinguish from medial or posterior dislocations, which have different code assignments.
