Inj lumbar, sacral and pelvic sympathetic nerves, sequela

This code signifies a long-term or late-effect complication resulting from a past injury to the sympathetic nerves located in the lower back, sacrum, or pelvis. These nerves are crucial for involuntary bodily functions, and their damage can lead to persistent issues such as chronic pain, autonomic dysfunction, or other neurological deficits.

Apply this code when documenting a patient presenting with ongoing symptoms directly attributable to a previous injury of the lumbar, sacral, or pelvic sympathetic nerves. This includes conditions like complex regional pain syndrome (CRPS) or persistent bowel/bladder dysfunction that developed as a consequence of such nerve damage.

• Always use this code as a secondary diagnosis, following the code for the specific sequela or current condition being treated.
• Ensure documentation clearly links the current symptoms to a past injury of the sympathetic nerves in the specified regions.
• Verify that the "S" seventh character is appropriate for a sequela, indicating a late effect of the injury.
