ICD-10-CM · FY 2026 POA Exempt
POA Exempt: Congenital malformations of the circulatory system (Q20-Q28) ICD-10-CM
The 102 ICD-10-CM codes in this range are exempt from Present on Admission reporting for fiscal year 2026. Hospitals assign no POA indicator for them on inpatient claims: the codes describe circumstances, such as pre-existing conditions or the cause of an injury, where asking whether the condition was present at admission adds no information.

Questions About This Category
Why are these codes POA exempt?
The codes for congenital malformations of the circulatory system describe circumstances where the Present on Admission question has no meaning, so CMS exempts them from the indicator. The exemption is published in the official FY 2026 CMS exempt file.
How many codes in this range are exempt?
The FY 2026 exempt list contains 102 codes in this range, effective October 1, 2025 through September 30, 2026.
Are these codes billable?
The exemption only removes the POA indicator requirement, it does not change how a code is used on claims. Billable status is shown per code: blue codes are billable, and any codes shown in the amber tone are category headers that need more characters.
