Lateral subluxation of unsp ulnohumeral joint, subs encntr

This code signifies a partial dislocation of the elbow joint, specifically affecting the ulnohumeral articulation, where the ulna and humerus meet. The "lateral" aspect indicates the displacement is towards the outside of the arm, and "unspecified" means the laterality (left or right) of the joint is not documented.

This code is appropriate for encounters following the initial treatment of a lateral ulnohumeral subluxation, such as follow-up appointments, cast changes, or physical therapy sessions. It should be used when the patient is receiving active treatment for the injury, but not for the initial diagnosis and treatment.

• Ensure documentation clearly indicates a "subsequent encounter" for this specific injury.
• Verify the injury is a "subluxation" (partial dislocation) and not a full "dislocation" (S53.13-).
• If laterality (left or right) is specified in the documentation, use the more specific code (S53.141- or S53.142-).
