What 36405 covers

This code represents venipuncture using a scalp vein in a child younger than 3 years when the procedure requires a physician’s or qualified health professional’s skill. It may be performed to obtain a blood specimen or for a therapeutic purpose, such as gaining venous access to administer treatment. The age and access site distinguish this service from other pediatric venipuncture codes.

Report the service when the documented procedure uses a scalp vein and the child is younger than 3 years; the record should support the site, age, and purpose. This code describes the venipuncture, not laboratory analysis of the specimen. When multiple procedures are performed in the same session, Medicare pays the highest-valued procedure in full and the others 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.

36405 billing questions

When should 36405 be chosen over 36400 or 36406?

Choose 36405 for a scalp vein in a child younger than 3 years. Codes 36400 and 36406 distinguish other venous sites in this age group.

Can 36405 be reported for routine blood collection?

Use it when the documented scalp-vein access in a child younger than 3 requires physician or qualified health professional skill. Routine venous collection is represented by 36415.

Does 36405 include testing the blood specimen?

No. It represents the venipuncture; laboratory analysis is a separate service when performed and reportable.

How does Medicare handle 36405 with other procedures in the same session?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the others at 50%.

What documentation supports reporting 36405?

Document the child's age, scalp-vein access, and whether the venipuncture was for specimen collection or a therapeutic purpose.

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.
