Injury of lumbosacral plexus, sequela

This code signifies a long-term or residual effect resulting from a past injury to the lumbosacral plexus. This could manifest as persistent pain, weakness, numbness, or altered sensation in the lower extremities, pelvis, or perineum, directly attributable to the original nerve damage. The initial acute injury has resolved, but its lasting impact continues to affect the patient.

Apply this code when documenting a patient presenting with chronic symptoms directly linked to a previously sustained lumbosacral plexus injury. This is appropriate for follow-up encounters where the sequelae are being managed, rather than the acute phase of the injury. Examples include ongoing neuropathic pain or motor deficits years after a traumatic event.

• Always use this code as a secondary diagnosis, following a code describing the specific manifestation of the sequela (e.g., chronic pain, muscle weakness).
• Ensure documentation clearly links the current symptoms to a past lumbosacral plexus injury, indicating the acute phase has passed.
• Verify that the seventh character "S" (sequela) is appropriate, indicating the long-term complication of the initial injury.
