About Y79.1
Y79.1 is the ICD-10-CM diagnosis code for therapeutic (nonsurgical) and rehabilitative orthopedic devices associated with adverse incidents. It belongs to category Y79 (orthopedic devices associated with adverse incidents), block Y70-Y82 (medical devices associated with adverse incidents in diagnostic and therapeutic use) 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 Y79 (orthopedic devices associated with adverse incidents), Y79.1 is specifically for therapeutic (nonsurgical) and rehabilitative orthopedic devices associated with adverse incidents. Related codes cover diagnostic and monitoring orthopedic devices associated with adverse incidents (Y79.0), prosthetic and other implants, materials and accessory orthopedic devices associated with adverse incidents (Y79.2), surgical instruments, materials and orthopedic devices (including sutures) associated with adverse incidents (Y79.3) and miscellaneous orthopedic devices associated with adverse incidents, not elsewhere classified (Y79.8).
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.
