How is code 75898 reported in conjunction with transcatheter embolization?

How is code 75898 reported in conjunction with transcatheter embolization? Is it reported for each follow-up angiogram performed, only once for each individual vessel embolized, or only once for the entire operative site embolized?

Answer:
Unlike angioplasty, completion angiography is not included in embolotherapy and infusion therapy.
With the exception of the intracranial or central nervous system, code 75898, Angiography through existing catheter for follow-up study for transcatheter therapy, embolization or infusion, is reported only once per operative field per session. Multiple vessels embolized in the same extremity are considered a single field. Code 75898 is used to report follow-up angiograms as necessary to document a satisfac-
tory endpoint of therapy once the embolization procedure has ended.

It would be appropriate to report code 75898 more than once on the same day of service, when more than one operative field is treated or when separate angiograms (performed at different sessions) are necessary to document a satisfactory endpoint of therapy. Modifier 59, Distinct procedural service, must be appended to diagnostic angiography codes when reported in conjunction with a therapeutic radiological supervision and interpretation code on the same date of service.

To illustrate, code 75898 may be reported twice (with modifier 59 appended) when postembolization angiograms are performed on two distinct operative fields at the same session (eg, bilateral renal cell carcinomas; multiple sites of trauma).
