CPT® 85025 or 85027? That is the Question
National Government Services (NGS) says Error Code (EC) 31 Services incorrectly coded denials have been increasing in relation to CPT® 85025 Blood count; complete (CBC), automated (Hgb, Hct, RBC, WBC and platelet count) and automated differential WBC count.
“Review of the CERT data shows that the CERT contractor has been re-coding CPT 85025 to show the appropriate service rendered,” NGS writes in its November 2009 Medicare Monthly Review (MMR). So how should billing staff code this service?
NGS says, generally, CPT® 85027 Blood count; complete (CBC), automated (Hgb, Hct, RBC, WBC and platelet count) is more appropriate.
Correct coding: If the physician has ordered only a CBC (with no mention of a differential), the correct code is 85027.
To prevent EC 31 denials, providers should review the medical records and the physician order/requisition before performing and coding the service to make sure what is being done and billed matches the order.
