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

This code signifies a long-term complication or late effect resulting from a previously sustained injury to an unspecified blood vessel in the left shoulder or upper arm. This could encompass chronic pain, nerve damage, or functional impairment directly attributable to the initial vascular trauma. The specific type of blood vessel involved is not documented.

Apply this code when documenting a patient presenting with a current condition that is a direct consequence of an old, resolved injury to a blood vessel in the left shoulder or upper arm. This is appropriate for follow-up encounters where the acute phase of the original injury has passed, but residual effects persist. Examples include chronic lymphedema, persistent ischemia, or neuropathy stemming from the initial vascular insult.

• Always sequence this sequela code after the code for the nature of the sequela (e.g., chronic pain, nerve palsy).
• Ensure documentation clearly links the current condition to a previous injury of a blood vessel in the specified anatomical area.
• This code is for "other specified" injuries, meaning the specific type of vascular injury was documented but does not have a more precise code.
