Inj unsp blood vessel at lower leg level, right leg, sequela

This code signifies a long-term complication or residual effect stemming from a previously sustained injury to a blood vessel in the right lower leg. The specific type of blood vessel (e.g., artery, vein) is not identified, and the initial injury itself is not precisely categorized beyond "other specified."

Apply this code when documenting a current condition that is a direct consequence of an old, resolved injury to an unspecified blood vessel in the right lower leg. Examples include chronic pain, nerve damage, or persistent swelling directly attributable to the past vascular trauma, after the acute phase of the original injury has passed.

• Ensure documentation clearly links the current condition to a previous blood vessel injury in the right lower leg.
• Only use this "S" (sequela) code for residual effects, not for the initial acute injury.
• If the specific blood vessel or type of injury is known, a more precise code should be selected.
