HACs set for October 1: Are you ready?
When a hospital-acquired-condition (HAC) is not present on admission (POA), and it is the only complication/comorbidity (CC) or major CC (MCC) on the claim, the case will group to a lower-weighted Medicare Severity DRG (MS-DRG). That means less reimbursement for your hospital.
“It could have a financial impact on the hospital’s bottom line,” says DeAnne W. Bloomquist, RHIT, CCS, a coding and compliance consultant and the president of Mid-Continent Coding, Inc., in Overland Park, KS.
The following eight HAC conditions take effect October 1:
- Foreign object retained after surgery. Codes 998.4 (foreign body accidentally left during a procedure) and 998.7 (acute reaction to a foreign substance accidentally left during a procedure) denote this HAC.
- Air embolism. Code 999.1 (air embolism to any site, following infusion, perfusion, or transfusion) denotes this HAC that refers to a condition in which air inadvertently passes through an open blood vessel.
- Blood incompatibility. Code 999.6 (ABO incompatibility reaction) denotes this HAC.
- Stages III and IV (decubitus) pressure ulcers. Code 707.23 indicates a stage III decubitus ulcer, and code 707.24 indicates a stage IV decubitus ulcer.
- Falls and trauma. This includes fractures, dislocations, intracranial injuries, crushing injuries, and burns. The following codes denote this HAC:
- Codes 800–829: Fractures
- Codes 830–839: Dislocations
- Codes 850-854: Intracranial injuries
- Codes 925–929: Crushing injuries
- Codes 940–949: Burns
- Codes 991–994: External causes (i.e., heat, air pressure, light, frostbite)
- Catheter-associated urinary tract infections (UTI). Code 996.64 (infection due to indwelling urinary catheter) denotes this HAC.
- Vascular catheter-associated infections. Code 999.31 (infection due to central venous catheter—catheter-related bloodstream infection, not otherwise specified) denotes this HAC.
- Mediastinitis after coronary artery bypass graft (CABG). Code 519.2 (mediastinitis) and a CABG procedure code from the 36.10–36.19 range denote this HAC.
