What 36585 covers

This service replaces the complete port-containing device used for central venous access when the access enters through a peripheral vein. The replacement uses the existing venous route; it is distinct from exchanging a standard PICC or replacing a centrally inserted tunneled catheter. Vascular access specialists, interventional radiologists, and surgeons may perform it in a hospital or procedural setting, commonly when the existing device requires complete replacement.

Report the code when documentation identifies a port-containing peripheral access device and supports complete replacement through the existing venous route. The record should distinguish this device from a non-ported PICC and from a centrally inserted catheter. Related postoperative visits during the 10-day global period are included. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

36585 billing questions

How is this different from 36584?

This code is for complete replacement of a port-containing peripheral central access device. Code 36584 applies to complete replacement of a PICC without a subcutaneous port.

Can this code be used for a newly placed device?

No. It describes replacement of an existing port-containing device through the existing peripheral venous route, not initial placement.

Is the 10-day postoperative care separately reportable?

Related postoperative visits during the 10-day global period are included in this procedure's payment.

Should modifier 50 be appended for bilateral access?

No. The descriptor and anatomy make bilateral adjustment inappropriate for this code.

When is assistant-at-surgery payment allowed?

Only when medical necessity for the assistant is documented. Co-surgeons and team surgery are not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
