Newborn Duodenoduodenostomy without Resection

Question:

The provider repairs a duodenal atresia in a newborn with a Diamond duodenoduodenostomy. Which CPT is more appropriate to bill for 44126-52 (for no resection done) or 44130-63 (Pt under 4 kg)?

Answer:

CPT guidelines advise us to “select the CPT code of the procedure or service that accurately identifies the procedure or service performed.” Because there is a CPT code that accurately captures the work performed without the use of the reduced services modifier, CPT 44130 would be the appropriate code to report the duodenoduodenostomy. Modifier 63 would be appended if the infant is less than 4 kg.
