This procedure is not a simple diagnostic lumbar puncture; it includestherapeutic drainageof CSF to relieve elevated intracranial pressure. CPT62272is used forspinal puncture with drainage of cerebrospinal fluid(therapeutic), which matches the “actively drain CSF” language. The physician also performed the puncture underCT guidance, and when imaging guidance is documented and not bundled into the primary code, you report the appropriate CT guidance code77012for needle placement. Option D (62270) is the classic diagnostic lumbar puncture/spinal puncture code and does not capture active drainage as the purpose. Options A and B are for different catheter/needle procedures and do not best match “spinal puncture with drainage” plus CT guidance in this vignette. CPC exam tip: when the stem emphasizespressure relief/drainage, thinktherapeutic drainage coderather than diagnostic LP, and then add imaging guidance when specifically documented and supported.
