The ICD-10-CM code for unavailability and inaccessibility of health-care facilities is Z75.3 (sometimes written as Z753). It is billable on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
Is Z75.3 (Problems related to medical facilities and other health care) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report unavailability and inaccessibility of health-care facilities on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does Z75.3 group to?
On inpatient claims, unavailability and inaccessibility of health-care facilities maps to MS-DRG 951 (other Factors Influencing Health Status), which carries a relative weight of 0.556. Higher weights mean higher Medicare reimbursement.
Can Z75.3 be a principal diagnosis?
No. The Medicare Code Editor rejects this code as a principal diagnosis because unavailability and inaccessibility of health-care facilities describes a circumstance that influences health status rather than a current illness. Report it as a secondary diagnosis.
Is Z75.3 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 unavailability and inaccessibility of health-care facilities on inpatient claims. The code appears in the Persons encountering health services in other circumstances (Z69-Z76) range of the CMS exempt list.
