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.
