Questions About Z91.041Overview
Is Z91.041 (Nonmedicinal substance allergy status) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report radiographic dye allergy status on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
Can Z91.041 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because radiographic dye allergy status describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
Is Z91.041 exempt from POA reporting?
Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for radiographic dye allergy status on inpatient claims.
What is the ICD-9 equivalent of Z91.041?
Under the General Equivalence Mappings, radiographic dye allergy status converts to ICD-9-CM V15.08 (hx-radiogrphc dye allrgy). The mapping is a direct match.
