Core POA & HAC Coding Skills
FY 2027 coding note: Use the official ICD-10-CM guidelines, current POA-exempt list and CMS HAC policy documents. POA reporting and HAC payment/quality programs involve different criteria; an N indicator does not automatically mean a condition is a reportable HAC.
Use this textbook to improve practical understanding of POA and HAC concepts, and explore MEDESUN’s medical coding and CCS-focused training programs.
