About Y92.815

Y92.815 is the ICD-10-CM diagnosis code for train as the place of occurrence of the external cause. 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 Y92.81 (transport vehicle as the place of occurrence of the external cause), Y92.815 is specifically for train as the place of occurrence of the external cause. Related codes cover car as the place of occurrence of the external cause (Y92.810), bus as the place of occurrence of the external cause (Y92.811), truck as the place of occurrence of the external cause (Y92.812), Airplane as the place of occurrence of the external cause (Y92.813), boat as the place of occurrence of the external cause (Y92.814), subway car as the place of occurrence of the external cause (Y92.816) and other transport vehicle as the place of occurrence of the external cause (Y92.818).

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 E849.8 (accidents occurring in other specified places).
