Re-exploration Laminectomy Billing

Question:

The patient had a re-do laminectomy for stenosis at L3-L4. Can code 63042 be used for this procedure?

Answer:
No. CPT 63042 is intended for a re-do discectomy and would be inappropriate to use for a re-do laminectomy. Rather, use 63047 for this service and modifier 22 may be appended if significant additional work is documented.
