Q: How would you code for placement of a bone flap from craniotomy into the subcutaneous tissue for storage? Is that integral to the procedure or is there a separate code for it?
A: Placement of the bone flap in the subcutaneous tissue for storage meets the root operation definition of Reposition (Moving to its normal location, or other suitable location, all or a portion of a body part). This is reported with code 0NS00ZZ, Reposition of skull, open approach.
Q: For Case Study #1 in the presentation, why is the body part Brain rather than Cerebral Hemisphere? The documentation states that there was a right frontotemporal parietal decompressive craniectomy. Isn’t that the right cerebral hemisphere?
A: The reference we used for this case study was Coding Clinic, Second Quarter 2016: Page 29, in which they advised coding a right frontotemporal parietal decompressive craniectomy to the body part Brain.
Q: How is Duragen repair of the dura coded?
A: When Duragen is used for routine repair of the dura mater during craniectomy, no code is assigned as it is integral to the operative closure. However, if a hole was inadvertently made in the dura during the procedure, requiring repair with Duragen, assign code 00U20KZ, Supplement dura mater with nonautologous tissue substitute, open approach. Duragen is a xenograft (animal tissue) composed of bovine dura mater or pericardium. (Source: Coding Clinic, Third Quarter 2014: Page 17).
Q: How is laparoscopically assisted placement of a ventriculoperitoneal shunt coded?
A: Assign codes 00163J6 (Bypass of cerebral ventricle to peritoneal cavity with synthetic substitute, percutaneous approach) and 0WJG4ZZ (Inspection of peritoneal cavity, percutaneous endoscopic approach) when a VP shunt is placed with laparoscopic assistance. Since the laparoscopy involves a different body part (peritoneal cavity) than the bypass procedure (cerebral ventricle), the procedure requires two codes.
