Z85.22 ICD-10-CM Code: Personal history of malignant neoplasm of nasal cavities, middle ear, and accessory sinuses

Z85.22 is the ICD-10-CM diagnosis code for personal history of malignant neoplasm of nasal cavities, middle ear, and accessory sinuses. A patient who previously had cancer in the nasal passages, middle ear, or sinuses but is no longer being treated for it. Z85.22 sits in the ICD-10-CM chapter for factors influencing health status and contact with health services (z00-z99), within the section covering persons with potential health hazards related to family and personal history and certain conditions influencing health status (z77-z99).

Z85.22 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.

This code encompasses multiple anatomical sites in the head and neck region; document the specific site if known.
