  1. For the permanent implantation of a spinal cord stimulator system following a successful trial, which combination of CPT codes is typically reported?

    Answer: 63650 (or 63655) for electrode array AND 63685 for the pulse generator

    Permanent spinal cord stimulator implantation requires separate codes for the electrode array (63650 percutaneous or 63655 open/laminectomy) and the pulse generator (63685), as they are distinct billable components.

  2. A surgeon performs a posterior lumbar microdiscectomy (laminotomy with herniated disc excision) at a single level. The primary CPT code is:

    Answer: 63030

    CPT 63030 describes laminotomy (hemilaminectomy) with decompression of nerve roots including excision of a herniated intervertebral disc at a single lumbar level.

  3. Neuroplasty and transposition of the ulnar nerve at the elbow is reported with:

    Answer: 64718

    CPT 64718 specifically describes neuroplasty and/or transposition of the ulnar nerve at the elbow.

  4. Insertion of a spinal neurostimulator pulse generator (implantable pulse generator) is reported with which CPT code?

    Answer: 63685

    CPT 63685 describes insertion or replacement of a spinal neurostimulator pulse generator or receiver.

  5. Destruction by neurolytic agent of a lumbar paravertebral facet joint nerve at a single level is reported with:

    Answer: 64635

    CPT 64635 describes destruction by neurolytic agent of the paravertebral facet joint nerve at the lumbar or sacral level, single level.

  6. Implantation of a tunneled intrathecal catheter for long-term drug delivery (connected to an implanted infusion pump) is reported with:

    Answer: 62350

    CPT 62350 describes implantation, revision, or repositioning of a tunneled intrathecal or epidural catheter for long-term drug delivery via an implanted pump.

  7. Posterior fossa craniectomy for decompression of a Chiari malformation is reported with which CPT code?

    Answer: 61343

    CPT 61343 describes craniectomy for posterior fossa decompression, which is the procedure performed for symptomatic Chiari malformation.
