Posterior subluxation of unsp radial head, init encntr

This diagnosis code signifies a partial dislocation of the radial head in a posterior direction, where the specific side (left or right) is not documented. This injury involves the radius bone of the forearm slipping partially out of its normal articulation with the humerus at the elbow joint.

Use this code for the initial treatment of a patient presenting with a posterior subluxation of the radial head when the medical record does not specify whether the injury occurred on the left or right arm. This is appropriate for the first encounter for this specific injury.

• Ensure the documentation explicitly states "posterior subluxation" and that the laterality is unspecified.
• Confirm this is the patient's initial encounter for this injury, not a follow-up or sequela.
• If laterality is documented (left or right), a more specific code should be selected.
