For a spinal puncture performed to rule out meningitis, which code is appropriate?

The appropriate code for a spinal puncture performed to rule out meningitis is 62270. This code specifically refers to a lumbar puncture, which is the procedure used to obtain cerebrospinal fluid (CSF) for diagnostic purposes, such as testing for infections like meningitis. The procedure involves inserting a needle into the lumbar region of the spine to collect the CSF, which is then analyzed in a laboratory.

Other codes in the options do not refer to procedures relevant to lumbar punctures or do not specify the use for diagnostic purposes associated with meningitis. Therefore, 62270 is the correct choice as it directly corresponds to the action being performed and the medical necessity surrounding the evaluation of potential meningitis.
