Understand Present on Admission (POA), Hospital-Acquired Conditions (HAC), POA indicators, MS-DRG impact, CDI documentation, and high-yield CCS/CDIP exam concepts.
This practical MEDESUN guide is designed to help AHIMA CCS and CDIP exam candidates, inpatient coders, CDI professionals, HIM professionals, and healthcare professionals understand how POA and HAC reporting affect coding, reimbursement, documentation, and quality measurement.

Present on Admission (POA) identifies whether a condition was present at the time the inpatient admission order occurs.
Conditions that develop during an ED, observation, or outpatient surgery encounter before the inpatient admission order are also considered POA.
POA is reported after the final ICD-10-CM codes have been determined. It does not determine whether a condition should be coded.
The guide covers the five POA outcomes:
Understand:
Learn how to handle:
Understand the 8 CMS-selected HAC categories, including:
Learn how a HAC with POA = N or U can affect MS-DRG assignment when the HAC is the relevant CC/MCC driving the higher-weighted DRG.
The guide also includes real-world financial examples demonstrating the potential reimbursement impact of POA determination.
Learn how CDI professionals can address:
Review high-yield concepts and practice scenarios involving:
Understanding POA and HAC helps professionals connect:
Clinical Documentation → Coding → POA Assignment → HAC Identification → MS-DRG → Reimbursement
Accurate POA documentation is particularly important for HAC reporting, DRG assignment, reimbursement, CDI, quality measurement, and exam preparation.
The guide also emphasizes a critical concept for both CCS and CDIP:
POA does not determine whether a condition should be coded. Code first, then assign POA.

POA means Present on Admission and identifies whether a condition was present when the inpatient admission order occurred.
The primary POA indicators are Y, N, U, W, and Exempt/Blank.
Y means the condition was present at the time of inpatient admission.
N means the condition was not present at admission and developed during the inpatient hospitalization.
U means the documentation is insufficient to determine whether the condition was present on admission.
W means the provider is clinically unable to determine whether the condition was present on admission.
HACs are selected conditions identified by CMS for which applicable POA and payment rules can affect Medicare reimbursement.
No. The guide emphasizes that coding is completed first and POA is assigned afterward.
Yes. The guide includes high-yield POA rules, HAC concepts, CDI strategies, and practice scenarios specifically for CCS/CDIP preparation.
