Inj unsp blood vessel at shldr/up arm, right arm, sequela

This code signifies a long-term complication or residual effect from a previous injury to a blood vessel in the right shoulder or upper arm, where the specific type of vessel damage is not further detailed. It indicates that the initial acute injury has resolved, but the patient continues to experience issues directly attributable to that vascular trauma.

Use this code when documenting follow-up care for a patient with persistent symptoms (e.g., pain, swelling, functional limitation, circulatory issues) in the right shoulder or upper arm that are directly linked to a past, unspecified blood vessel injury in that region. This applies after the initial treatment for the acute injury has concluded, and the current encounter addresses the lasting impact.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, circulatory insufficiency) if known.
• Ensure documentation clearly links the current condition to a previous blood vessel injury in the specified anatomical area.
• Verify laterality (right arm) is accurately reflected in the medical record.
