Z45.31Encounter for adjustment and management of implanted visual substitution device

Z45.31 is the ICD-10-CM diagnosis code for encounter for adjustment and management of implanted visual substitution device. It belongs to category Z45 (encounter for adjustment and management of implanted device), block Z40-Z53 (Encounters for other specific health care) 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 Z45.3 (encounter for adjustment and management of implanted devices of the special senses), Z45.31 is specifically for encounter for adjustment and management of implanted visual substitution device. Related codes cover hearing device (Z45.32).

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 123 (Neurological Eye Disorders, relative weight 0.822), in MDC 02 (Diseases and Disorders of the Eye), 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 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 V53.09 (fitting and adjustment of other devices related to nervous system and special senses).
