Reaction to spinal or lumbar puncture

This code signifies an adverse physiological response or complication arising directly from a spinal tap (lumbar puncture) procedure. It encompasses a range of symptoms such as headache, nausea, vomiting, or localized pain that develop after the procedure.

Assign this code when documentation clearly indicates a patient experienced an adverse reaction attributable to a spinal or lumbar puncture. This typically includes post-dural puncture headache (PDPH) or other immediate or delayed complications directly linked to the procedure.

• Always sequence this code as a secondary diagnosis, following the code for the underlying condition for which the lumbar puncture was performed.
• Ensure the medical record explicitly links the symptoms to the lumbar puncture; avoid using for unrelated headaches or nausea.
• Differentiate from complications of anesthesia (e.g., nerve injury from regional block), which would be coded elsewhere.
