Medicare pays $33.73 for 36592 nationally in the office. Local office rates run $28.86–$48.34.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 36592 covers

Code 36592 covers obtaining a blood specimen through an established central or peripheral venous catheter, commonly a PICC. It represents the collection, not catheter insertion, replacement, or laboratory analysis. A nurse or other qualified clinical staff member may obtain the sample in an outpatient setting; the specimen can then be submitted for ordered testing.

Report 36592 when blood is collected through an established venous catheter, and document the access device and collection method. Use 36591 for collection from a completely implantable venous access device. CMS limits payment for this minor service to a day when no other physician service is billed. CMS identifies 36592 as technical-component-only and notes that a separate code covers interpretation.
