What 36593 covers
This service treats an obstructed vascular access device by instilling a thrombolytic agent into the device to dissolve the material blocking flow. Examples include a central venous catheter used for dialysis or an implanted infusion port that will not flush or provide adequate blood return. The service is performed by a clinician managing the access device in settings such as an office, infusion center, dialysis unit, or hospital. It describes thrombolytic treatment rather than mechanical extraction of an obstruction or replacement of the catheter.
Report 36593 when the documented service is thrombolytic declotting of the vascular device. Documentation should identify the affected device, the patency problem, the treatment performed, and the response or outcome. If the drug is separately supplied and reportable, its drug code may also be reported. CMS classifies 36593 as a technical-component-only service; a separate code covers interpretation. The reported service therefore represents the technical work, not an interpretation component.
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.

36593 billing questions
When should 36593 be used instead of 36595 or 36596?
Use 36593 for thrombolytic treatment of an obstructed vascular device. Codes 36595 and 36596 describe mechanical removal of an intraluminal obstruction, using different approaches.
Does 36593 include the thrombolytic drug?
The service is the thrombolytic treatment of the device. When the drug is separately supplied and reportable, report the applicable drug code as well, supported by the medication record.
Does 36593 include interpretation?
No. CMS identifies 36593 as technical-component-only; a separate code covers interpretation.
What documentation supports reporting 36593?
Document which vascular device was obstructed, the clinical patency problem, the thrombolytic treatment performed, and the treatment response.
Is 36593 appropriate for a catheter exchange?
No. It represents thrombolytic declotting, not catheter replacement. Report the applicable replacement service when the catheter is exchanged.
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.
