Unsp inj unsp bld vess at abd, low back and pelv level, sqla

This code signifies a long-term or late effect of an unspecified injury to an unspecified blood vessel located within the abdominal, lower back, or pelvic regions. It indicates that the initial injury has resolved, but residual symptoms or conditions persist as a direct result of that past trauma.

Apply this code when documentation clearly indicates a sequela (e.g., chronic pain, scar tissue, functional impairment) stemming from a previously sustained, but now healed, unspecified blood vessel injury in the specified anatomical areas. This is appropriate when the specific blood vessel or the exact nature of the original injury is not documented.

• Always ensure the "S" seventh character for sequela is appropriate, indicating a late effect.
• Avoid using this code if the specific blood vessel (e.g., femoral artery, renal vein) or the type of injury (e.g., laceration, contusion) is known and documented.
• Pair this code with an external cause code (V00-Y99) if the original injury's cause is known and relevant to the sequela.
