What 36400 covers

This service captures a difficult venous blood draw from the femoral or jugular vein in a child younger than three when access requires a physician’s or qualified health care professional’s skill. It is typically used to obtain a diagnostic blood specimen when routine peripheral access is not suitable. The code describes venipuncture, not placement of a central venous catheter or surgical venous cutdown. Documentation should identify the child’s age, access site, and circumstances supporting skilled access.

Select the code by both age and vein: scalp vein access and access through another vein in this age group have separate codes, while skilled venipuncture in an older patient falls under a different code. When multiple procedures are performed in the same session, CMS pays the highest-valued procedure in full and applies a 50% payment reduction to the others.

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.

36400 billing questions

When is 36400 appropriate instead of routine venipuncture?

Use it for a skilled femoral or jugular blood draw in a child younger than three. Routine venous collection is represented by 36415.

How does 36400 differ from 36405 and 36406?

The venipuncture site distinguishes these codes: 36400 is for femoral or jugular access, 36405 for scalp access, and 36406 for another vein in a child younger than three.

Does 36400 describe central venous catheter placement?

No. It describes venipuncture for a blood specimen, not placement of a central venous catheter.

How does the multiple procedure reduction affect 36400?

When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are paid at 50%.

What documentation supports reporting 36400?

Document the child’s age, femoral or jugular access site, and the clinical circumstances requiring skilled venipuncture.

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.
