Unsp inj unsp blood vess at hip and thi lev, unsp leg, sqla

This code signifies a long-term or late effect of an injury to an unspecified blood vessel in the hip or thigh region of an unspecified leg. The original acute injury has resolved, but the patient continues to experience residual symptoms or complications directly attributable to that past vascular trauma.

This code is appropriate when documentation clearly indicates a sequela (e.g., chronic pain, functional limitation, scar tissue affecting vascular flow) resulting from a prior, unspecified blood vessel injury in the hip or thigh. It should be used when the specific blood vessel or the exact nature of the initial injury is not documented, and the affected leg is also unspecified.

• Always assign a sequela code as a secondary diagnosis, following the code for the specific residual condition.
• Avoid using this code if the specific blood vessel (e.g., femoral artery, saphenous vein) or the nature of the initial injury is known; a more specific code should be sought.
• Ensure the "S" seventh character is appended to indicate a sequela.
