Y92.538Other ambulatory health services establishments as the place of occurrence of the external cause

Y92.538 is the ICD-10-CM diagnosis code for other ambulatory health services establishments 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 Y92.53, choose Y92.538 (Other ambulatory health services establishments as the place of occurrence of the external cause) only when documentation doesn't support a more specific option: ambulatory surgery center as the place of occurrence of the external cause (Y92.530), health care provider office as the place of occurrence of the external cause (Y92.531) and Urgent care center as the place of occurrence of the external cause (Y92.532).

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

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).
