About Y93.9

Y93.9 is the ICD-10-CM diagnosis code for activity, unspecified. It belongs to category Y93 (activity codes), 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 Y93, choose Y93.9 (Activity, unspecified) only when documentation doesn't support a more specific option: activities involving walking and running (Y93.0), activities involving water and water craft (Y93.1), activities involving ice and snow (Y93.2), activities involving climbing, rappelling and jumping off (Y93.3), activities involving dancing and other rhythmic movement (Y93.4), activities involving other sports and athletics played individually (Y93.5), activities involving other sports and athletics played as a team or group (Y93.6), activities involving other specified sports and athletics (Y93.7) and 13 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 E030 (unspecified activity).

Note
  • Category Y93 is provided for use to indicate the activity of the person seeking healthcare for an injury or health condition, such as a heart attack while shoveling snow, which resulted from, or was contributed to, by the activity. These codes are appropriate for use for both acute injuries, such as those from chapter 19, and conditions that are due to the long-term, cumulative effects of an activity, such as those from chapter 13. They are also appropriate for use with external cause codes for cause and intent if identifying the activity provides additional information on the event. These codes should be used in conjunction with codes for external cause status (Y99) and place of occurrence (Y92).
