Contact with blunt object, undetermined intent (Y29)

The ICD-10 code Y29 describes injuries caused by contact with a blunt object where the intent behind the injury is not known. This code and its variations help healthcare providers record and classify blunt force injuries when it is unclear whether they were accidental or intentional.

The section includes codes for different stages of treatment: Y29.XXXA covers the initial encounter, Y29.XXXD is for subsequent encounters, and Y29.XXXS is used when there are residual effects or complications (sequela). These codes apply to a variety of blunt injuries, such as those to the eye, thorax, back, or abdomen, often referred to as blunt injury or blunt trauma. By providing specific codes for undetermined intent, the ICD-10 coding system allows accurate medical documentation and reporting for cases where the cause of blunt force injury cannot be confirmed as accidental or intentional. This also aids in proper data analysis and resource allocation for such injuries.

Instructional Notations

7th Character Note

Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.

  • The appropriate 7th character is to be added to code Y29
