Z13.5Encounter for screening for eye and ear disorders

Z13.5 is the ICD-10-CM diagnosis code for encounter for screening for eye and ear disorders. It belongs to category Z13 (encounter for screening for other diseases and disorders), block Z00-Z13 (persons encountering health services for examinations) 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 Z13 (encounter for screening for other diseases and disorders), Z13.5 is specifically for encounter for screening for eye and ear disorders. Related codes cover screening for diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (Z13.0), screening for diabetes mellitus (Z13.1), screening for nutritional, metabolic and other endocrine disorders (Z13.2), screening examination for mental health and behavioral disorders (Z13.3), screening for certain developmental disorders in childhood (Z13.4), screening for cardiovascular disorders (Z13.6), screening for genetic and chromosomal anomalies (Z13.7), screening for other specified diseases and disorders (Z13.8) and 1 more.

The conditions in its Excludes2 note aren't part of Z13.5, but may be coded alongside it if the patient has both: encounter for general hearing examination (Z01.1-) and encounter for general vision examination (Z01.0-).

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 V80.1 (screening for glaucoma), V80.2 (screening for other eye conditions) and V80.3 (screening for ear diseases).
