About Y92.523

Y92.523 is the ICD-10-CM diagnosis code for highway rest stop 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 Y92.52 (service areas as the place of occurrence of the external cause), Y92.523 is specifically for highway rest stop as the place of occurrence of the external cause. Related codes cover Airport as the place of occurrence of the external cause (Y92.520), bus station as the place of occurrence of the external cause (Y92.521), railway station as the place of occurrence of the external cause (Y92.522) and gas station as the place of occurrence of the external cause (Y92.524).

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 E849.6 (accidents occurring in public building).
