About Z82.2
Z82.2 is the ICD-10-CM diagnosis code for family history of deafness and hearing loss. It belongs to category Z82 (family history of certain disabilities and chronic diseases (leading to disablement)), block Z77-Z99 (persons with potential health hazards related to family and personal history and certain conditions influencing health status) and chapter 21 (factors influencing health status and contact with health services). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within Z82 (family history of certain disabilities and chronic diseases (leading to disablement)), Z82.2 is specifically for family history of deafness and hearing loss. Related codes cover epilepsy and other diseases of the nervous system (Z82.0), blindness and visual loss (Z82.1), stroke (Z82.3), ischemic heart disease and other diseases of the circulatory system (Z82.4), asthma and other chronic lower respiratory diseases (Z82.5), arthritis and other diseases of the musculoskeletal system and connective tissue (Z82.6), congenital malformations, deformations and chromosomal abnormalities (Z82.7) and other disabilities and chronic diseases leading to disablement, not elsewhere classified (Z82.8).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
It is not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.
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 V19.2 (family history of deafness or hearing loss).
