Blood Brain Barrier

Effective October 1, 2007, a new code 00.19 has been created to identify a disruption of the blood brain barrier (BBBD) via infusion. The blood brain barrier (BBB) represents a substantial impediment to the delivery of chemotherapy to brain tumors. The BBB is the lining of the small blood vessels in the brain, which prevents many substances such as toxins or drugs from entering the brain. Because most chemotherapy drugs do not cross the BBB very well, patients may receive inadequate doses of chemotherapy to their brain tumors via conventional medical deliver methods–â€&ldquo...

Article Overview

This article covers an October 1, 2007 coding update for blood brain barrier disruption via infusion and explains the clinical context of intra-arterial chemotherapy delivery to the brain. It is intended for coders and revenue cycle professionals who need to understand the documentation context, associated code references, and the relationship between the barrier-disruption procedure and chemotherapy encounters.

Why This Topic Matters

Accurate reporting of this type of specialized infusion-based procedure depends on recognizing the relevant coding update and the surrounding chemotherapy admission context. The article helps readers determine whether an encounter is primarily for chemotherapy and how the blood brain barrier disruption is discussed in coding terms.
