Y92.9Unspecified place or not applicable

Y92.9 is the ICD-10-CM diagnosis code for unspecified place or not applicable. It belongs to category Y92 (place of occurrence of the external cause), block Y90-Y99 (Supplementary factors related to causes of morbidity classified elsewhere) and chapter 20 (external causes of morbidity). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Y92, choose Y92.9 (Unspecified place or not applicable) only when documentation doesn't support a more specific option: non-institutional (private) residence as the place of occurrence of the external cause (Y92.0), Institutional (nonprivate) residence as the place of occurrence of the external cause (Y92.1), school, other institution and public administrative area as the place of occurrence of the external cause (Y92.2), sports and athletics area as the place of occurrence of the external cause (Y92.3), street, highway and other paved roadways as the place of occurrence of the external cause (Y92.4), trade and service area as the place of occurrence of the external cause (Y92.5), industrial and construction area as the place of occurrence of the external cause (Y92.6), farm as the place of occurrence of the external cause (Y92.7) and 1 more.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as E849.9 (accidents occurring in unspecified place).
