Transfusion Reaction September 2008 Coding and Maintenance Committee Meeting Presented by Patrick S. Romano, MD, MPH on behalf of the Agency for Healthcare Research and Quality

Background Transfusion reactions occur when antibodies in the patient’s blood react to components in the transfused blood Transfusion reactions occur when antibodies in the patient’s blood react to components in the transfused blood Can be life threatening or minor Can be life threatening or minor Types of transfusion reaction Types of transfusion reaction – Major types: ABO and Rh – Minor types: e.g. Kell, Duffy, Kidd, Lewis, E Minor antigens may cause serious or mild reactions, but are uncommon in the general population (major risk factor is prior transfusion therapy) Minor antigens may cause serious or mild reactions, but are uncommon in the general population (major risk factor is prior transfusion therapy)
3
Preventing transfusion reaction Major antibodies (ABO/Rh) routinely screened through type and cross in non-emergent cases Major antibodies (ABO/Rh) routinely screened through type and cross in non-emergent cases Minor antibodies are not screened, unless patient has a history of transfusion reaction to one of these minor antibodies Minor antibodies are not screened, unless patient has a history of transfusion reaction to one of these minor antibodies Failure to screen or faulty screening for major antibodies before non-emergent transfusions is a serious medical error (usually occurs at POC) Failure to screen or faulty screening for major antibodies before non-emergent transfusions is a serious medical error (usually occurs at POC) – National Quality Forum Serious Reportable Event – AHRQ Patient Safety Indicator – CMS Hospital Acquired Condition

Current Coding Structure 999.6 ABO incompatibility reaction 999.6 ABO incompatibility reaction – Index instructs coders to code minor specified blood group antigens (Duffy, E, Kell, Kidd, Lewis, M, N, P, S) to 999.6 This code combines preventable ABO reactions with those generally considered nonpreventable in most patients This code combines preventable ABO reactions with those generally considered nonpreventable in most patients Record review study (7 cases) by National Association of Children’s Hospitals and Related Institutions (NACHRI) in 2008: 2 POA, 4 clearly nonpreventable, 1 uncertain Record review study (7 cases) by National Association of Children’s Hospitals and Related Institutions (NACHRI) in 2008: 2 POA, 4 clearly nonpreventable, 1 uncertain

Proposed coding structure 999.6 ABO incompatibility reaction 999.6 ABO incompatibility reaction – Exclude minor blood group antigens Add new code Add new code – 999.87 “Other specified transfusion reaction” Revise 999.89 Revise 999.89 – Unspecified transfusion reaction Permits tracking of ABO and minor incompatibility reactions separately Permits tracking of ABO and minor incompatibility reactions separately Limits 999.6 to preventable reactions Limits 999.6 to preventable reactions
