Inj oth blood vessels at shldr/up arm, right arm, sequela

This code indicates a long-term complication or residual effect stemming from a past injury to a blood vessel in the right shoulder or upper arm, excluding the main arteries and veins. These sequelae could include chronic pain, impaired circulation, nerve damage secondary to vascular compromise, or persistent swelling. The original injury itself is no longer acute, but its lasting impact on the patient's health is being addressed.

This code is appropriate when documenting a patient presenting with a current condition that is a direct result of a previous, resolved injury to a minor blood vessel in the right shoulder or upper arm. Examples include chronic venous insufficiency following a past crush injury, persistent lymphedema due to an old vascular laceration, or neuropathy from a prior hematoma compressing a vessel. It should be used when the focus of care is on the residual effect, not the original injury.

• Always assign an additional code to specify the nature of the sequela (e.g., chronic pain, lymphedema).
• Ensure documentation clearly links the current condition to a past injury of a specified, but not major, blood vessel in the right upper extremity.
• Do not use this code for acute injuries; "S" codes are exclusively for sequelae.
