Unsp inj blood vessels at shldr/up arm, left arm, sequela

This code signifies a long-term or late effect of an unspecified injury to a blood vessel (other than the main arteries or veins) in the left shoulder or upper arm region. The original injury is no longer acute, and the patient is experiencing residual symptoms or complications.

Use this code when documenting a patient presenting with ongoing issues, such as chronic pain, numbness, or impaired function, that are directly attributable to a past, unspecified blood vessel injury in the left shoulder or upper arm. This applies when the initial injury has healed, but its effects persist.

• Requires a seventh character "S" to indicate sequela, meaning the residual effect of a past injury.
• Ensure documentation clearly links the current symptoms to a previous blood vessel injury in the specified anatomical area.
• Avoid using this code for acute injuries; instead, use the appropriate acute injury code with the correct seventh character.
