Answer: The best choice from ICD-9 is 349.0 (Reaction to spinal or lumbar puncture). The descriptor includes the notation of "Headache following lumbar puncture," which could be the situation for the patient in question.

Bonus tip: Although many code descriptors will undergo changes when ICD-10 becomes effective in October 2013, 349.0's ICD-10 counterpart will look virtually the same. The new ICD-10 code will be G97.1 (Other reaction to spinal and lumbar puncture). The accompanying notation of included conditions states, "Headache due to lumbar puncture."
