Posterior subluxation of unsp ulnohumeral joint, init encntr

This diagnosis code signifies a partial dislocation of the elbow joint, specifically where the ulna bone has shifted backward relative to the humerus. The "unspecified" nature indicates that the laterality (left or right) of the affected elbow is not documented.

This code is appropriate for initial encounters with a patient presenting with a newly diagnosed posterior subluxation of the elbow, where the specific side of the body is not yet determined or documented. This might occur in emergency department settings or initial evaluations following an injury.

• Ensure documentation clearly states "posterior subluxation" and not a complete dislocation.
• If the laterality (left or right) is known, a more specific code should be used.
• The "A" suffix indicates an initial encounter; use subsequent encounter or sequela codes for follow-up care.
