Coding Brief: Hexagonal Phospholipid Neutralization (Code 85598) (April 2011)
April 2011 page 9 Coding Brief: Hexagonal Phospholipid Neutralization (Code 85598) Antiphospholipid antibodies are directed at phospholipid/protein complexes that have the ability to prolong the clotting times of the phospholipid-dependent coagulation tests. Antiphospholipid antibodies may be associated with systemic lupus erythematosis and are commonly referred to as lupus anticoagulants (LA). However, they can also occur in patients without lupus. These antibodies are an important cause of both arterial and deep venous thrombosis, pulmonary embolus, acute myocardial infarction or stroke, and may be associated with the development of recurrent abortion, intrauterine growth restriction, and preeclampsia. The clinical syndromes associated with...

Article Overview
This CPT coding brief covers laboratory evaluation related to antiphospholipid antibodies, including how the hexagonal phospholipid neutralization procedure fits among other coagulation-related tests discussed in CPT 2011. It is useful for coders, laboratory billing staff, and compliance readers who need to understand the article’s scope, the testing context, and the distinctions among the procedures referenced.
Why This Topic Matters
Articles like this help coding professionals understand where a laboratory procedure fits within CPT and how it is discussed relative to nearby coagulation testing services. That can support accurate code recognition, documentation review, and broader lab coding education without replacing the full article.
