Postlaminectomy syndrome, not elsewhere classified

This code identifies a chronic pain condition that persists or develops after lumbar spine surgery (laminectomy), despite the surgery being considered anatomically successful. It encompasses a range of symptoms including persistent back pain, leg pain, or neurological deficits that were not present pre-operatively or have worsened post-operatively. This syndrome is also commonly referred to as "failed back surgery syndrome" (FBSS).

Use this code when documentation clearly indicates a patient is experiencing ongoing or new pain and/or neurological symptoms following a laminectomy, and these symptoms are not attributable to other specific post-surgical complications like infection or hardware failure. Supporting documentation should detail the prior laminectomy and the current chronic pain presentation.

• Ensure the documentation specifies a laminectomy as the prior surgical procedure, not other spinal surgeries like fusion or discectomy alone.
• This code should be used for the syndrome itself, not for specific complications like pseudoarthrosis or hardware complications, which have their own distinct codes.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, followed by codes for specific pain sites or neurological symptoms if applicable.
