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

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.
