Posterior dislocation of left sternoclavicular joint, subs

This code describes a posterior displacement of the left sternoclavicular joint, meaning the clavicle has moved backward relative to the sternum. This injury specifically refers to a follow-up visit or encounter for a patient who has already received initial treatment for this dislocation.

Use this code for any subsequent encounter where a patient is being seen for ongoing management, follow-up, or complications related to a previously diagnosed and treated posterior dislocation of the left sternoclavicular joint. This includes visits for physical therapy, re-evaluation, or monitoring of healing.

• Ensure the encounter is not for the initial treatment of the dislocation; use an "A" (initial encounter) seventh character for the first visit.
• Verify the laterality is correctly documented as "left" and the dislocation is specifically "posterior."
• Confirm that the documentation supports a subsequent encounter, such as "follow-up," "re-evaluation," or "post-operative visit."
