This online tool provides a list of HCAC (Healthcare Acquired Conditions) ICD-10 codes as depicted in Appendix V, Part 1, Section III.A in association with the All Provider manual. HCACs are conditions occurring in an inpatient hospital setting that Medicare designates as hospital-acquired conditions (HACs), with the exception of deep vein thrombosis (DVT)/pulmonary embolism (PE) following total knee or total hip replacement in pediatric (under 21 years) and obstetrics patients. The HCACs, and associated ICD-10-CM diagnosis codes and ICD-10 PCS codes listed, are subject to change as a result of revisions to the list of HACs and related codes made by CMS under Medicare. CMS’s changes to the Medicare HAC-list and related codes shall be deemed to take effect automatically as of the effective date of the CMS updates under Medicare, without the need for an amendment to this list. 

For the most current list of HACs providers should refer to the CMS website at
