Activity codes (Y93) ICD-10-CM
The Y93 code range covers activity codes with 131 ICD-10-CM diagnosis codes. 109 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
- 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 Y92

About the Y93 Code Range
The Y93 series of ICD-10 codes specify activity codes that describe the physical or recreational activities a person was engaged in when an injury or health issue occurred. These codes help clarify the circumstances related to an external cause by pinpointing the exact activity involved.
This section includes codes for a wide range of activities, from walking and running (Y93.0) to water sports like swimming (Y93.11) and underwater diving (Y93.15), as well as ice and snow activities, climbing, dancing, individual and team sports, and even caregiving or household maintenance. For example, the ICD-10 code for swimming (Y93.11) covers injuries such as collisions and drowning incidents, often referred to with synonyms like "Injury to swimmer by watercraft propeller" or "Accidental drowning while swimming." Similarly, Y93.55 addresses injuries related to bike riding, helping coders capture activity-specific external causes. These codes serve as essential tools for medical coders and health professionals to accurately document how an injury happened in relation to specific actions or sports.
