What Does POA-Exempt Mean in FY2027 ICD-10-CM?

POA-exempt means the present-on-admission indicator is not applicable to a code on the official FY2027 exempt list; it does not mean the condition was absent on admission. “Exempt from POA reporting” means a present-on-admission (POA) indicator is not applicable to a code on the official exempt list. It is a reporting designation, not a conclusion that the condition was absent. In the FY2027 Official Guidelines, Appendix I, “N” separately means a condition was not present at the time of inpatient admission. The same appendix says to leave the POA field blank when the code is on the exempt list; it calls this the only circumstance in which that field may be left blank.

This guide uses the U.S. ICD-10-CM FY2027 release. CDC/NCHS dates that release from October 1, 2026 through September 30, 2027. The question here is how to read the official file and reporting rule, not whether any individual diagnosis should be coded or what a claim will be paid.

Appendix I of the FY2027 guidelines applies the POA indicator to diagnosis and external-cause codes on relevant institutional claims. It says the POA guidance supplements the main coding guidelines: first determine the final reportable codes under the ordinary rules, then address POA for those codes. A code being POA-exempt does not itself make a diagnosis reportable, and a condition that is not reported has no POA indicator to assign.

The general reporting requirement covers inpatient admissions to general acute care hospitals and other facilities subject to a POA-reporting law or regulation. CMS also distinguishes facilities affected by its POA indicator requirement. A code-level exemption in the FY2027 list and a facility-level reporting rule are separate checks. Do not use this inpatient workflow as a blanket rule for an outpatient visit.

CMS publishes the FY2027 Present on Admission Exempt List from its POA coding page. The ZIP contains a readme and a full text/spreadsheet list with the FY2027 code and long description, plus separate files for additions, deletions and revisions. The readme identifies the full list as the FY2027 POA-exempt list; use the full list to check membership rather than treating a change-only file as the entire set.

Start with the final code from the applicable versioned FY2027 ICD-10-CM reference, including its complete characters and Tabular context. Then compare that exact code with the official FY2027 exempt file. A broad category title, a previous fiscal year's flag or a third-party search snippet is not a substitute for the current code-level entry. Keep the ZIP URL and release label with the result so another reader can reproduce the check. The October release-boundary guide explains why the work date matters.

For a final reportable code in a setting where POA reporting applies, the FY2027 Appendix I instructions create a short decision path:

Diagram-ready takeaway: final reportable code → check exact code in the FY2027 exempt list → if listed, POA not applicable; otherwise, follow Appendix I. Do not infer a clinical status from the file label. If code selection, documentation or claim format is uncertain, resolve that uncertainty through the responsible coding and provider workflow.

Appendix I defines Y as present at inpatient admission and N as not present. U means the documentation is insufficient to determine POA; W means the provider cannot clinically determine it. The same appendix labels an exempt code “unreported/not used.” These are different reporting meanings. An exempt code is not a disguised “N,” and a missing explanation in the record is not permission to treat a non-exempt code as exempt.

“Present on admission” is measured when the inpatient admission order occurs, not simply when someone first notices or documents a condition. Appendix I expressly warns that a diagnosis confirmed days later may still have been present earlier. That timing judgment belongs to the applicable rule and provider documentation; this article does not assign an indicator to a patient. It explains why the official exemption file must be consulted before interpreting a blank field.

A reproducible review note can record: “U.S. ICD-10-CM FY2027; final code [verified code]; CMS FY2027 POA-exempt ZIP [full-list entry found or not found]; Appendix I section; applicable inpatient reporting setting.” Fill those brackets only after a real source check. For the diagnosis itself, the FY2027 source-file library and parent-note review guide help you retrace the Index-to-Tabular context before addressing POA.

The ICD Code Hub apps for iPhone, Android and Mac provide convenient access to available versioned reference routes while reviewing a code. Use the official CMS exempt ZIP and Appendix I for the POA reporting rule; the shared store links below lead to the current app listings. A saved lookup should carry its FY2027 label and source URL so it is not silently reused for a different fiscal year.
