What 36563 covers

This service places a tunneled central venous access device with a subcutaneous port and two catheters. A surgeon or interventional radiologist typically performs the procedure in an operating room or procedural suite when the treatment plan requires two catheter pathways for ongoing access, such as for distinct infusion needs. The implanted port provides access through the skin after the insertion sites heal.

Select this code when the documented device configuration requires two catheters and includes a subcutaneous port; a single-catheter port or a tunneled catheter without a port is a different service. The operative report should establish the tunneled central placement, port configuration, and need for both catheters. Medicare assigns a 10-day global period, so related postoperative visits during that period are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others 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.

36563 billing questions

How does this differ from 36561?

This code is for a port device requiring two catheters. Code 36561 describes a tunneled port placement with a single catheter.

When should 36558 be considered instead?

Use 36558 for a tunneled central venous catheter without a subcutaneous port in a patient age 5 or older. The port and two-catheter configuration distinguish this service.

Are related postoperative visits separately payable during the global period?

Related postoperative visits within the 10-day global period are included in the procedure payment.

Can modifier 50 be reported for two catheters?

No. The two-catheter device configuration is not a bilateral service, and modifier 50 is inappropriate.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment is available only when medical necessity is documented. Co-surgeons and team surgery are not permitted.

What happens when another procedure is performed in the same session?

The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple procedure reduction.

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.
