What 36600 covers

This service covers obtaining an arterial specimen by puncturing an artery, commonly the radial artery, with a needle. It is often performed at the bedside in an emergency department, hospital, or outpatient setting when arterial blood is needed for blood-gas or other diagnostic testing. A physician or other qualified clinician may perform the collection; the laboratory analysis is a separate service.

Report the puncture when arterial blood is actually collected, not for venous sampling or simply because an arterial catheter is present. Documentation should identify the reason for arterial sampling and support that an arterial specimen was obtained. Report the applicable laboratory analysis separately when performed and separately reportable. Under the CMS multiple-procedure reduction rule, when this service is performed in the same session as other procedures subject to that reduction, the highest-valued procedure is paid in full and the others are paid at 50%.

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.

36600 billing questions

When should 36600 be reported instead of 36620?

Use 36600 for a percutaneous arterial puncture to collect a specimen. Code 36620 describes placement of an arterial catheter, generally for ongoing access or monitoring.

Does 36600 include blood-gas analysis?

No. The puncture collects the specimen; report the applicable laboratory analysis separately when performed and separately reportable.

Is 36600 reported for venous blood collection?

No. It represents collection from an artery; venous collection is coded according to the venipuncture service performed.

How many units should be reported for multiple tests from one draw?

The code represents the arterial collection, not each analyte tested. Do not count separate blood-gas results as separate arterial punctures.

How does the multiple-procedure reduction affect 36600?

When the reduction applies to procedures performed in the same session, the highest-valued procedure is paid in full and the other procedures are paid at 50%.

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.
