HAC meaning in Medical ?
Answer: What is Hospital-acquired condition mean?
A hospital-acquired condition (HAC) is an undesirable situation or condition that affects a patient and that arose during a stay in a hospital or medical facility. It is a designation used by Medicare/Medicaid in the US for determining MS-DRG reimbursement beginning with version 26 (October 1, 2008). Not only hospital-acquired infections but also any other situation or condition, such as pressure ulcers, blood type mismatch, or iatrogenic injury, can be a HAC.
A patient at a hospital can be infected or otherwise degraded by hospital conditions and/or personnel in ways that are sometimes diagnosed as a "complication." The US Medicare system designates some 1000+ ICD-9-CM diagnoses, out of over 14000 (as of 2009), as possible HACs. On February 8, 2006, the President signed the Deficit Reduction Act (DRA) of 2005. Section 5001(c) of DRA requires the Secretary to identify conditions that are: (a) high cost or high volume or both, (b) result in the assignment of a case to a DRG that has a higher payment when present as a secondary diagnosis, and (c) could reasonably have been prevented through the application of evidence-based guidelines. Section 5001(c) provides that CMS can revise the list of conditions from time to time, as long as it contains at least two conditions. On July 31, 2008, in the inpatient prospective payment system (IPPS) fiscal year (FY) 2009 Final Rule, the Centers for Medicare & Medicaid Services (CMS) selected 10 categories of conditions for a HAC payment provision. For discharges occurring on or after October 1, 2008, hospitals no longer receive additional payment for cases in which one of the selected conditions was not present on admission. That is, the case would be paid as though the secondary diagnosis were not present.
