About Z96.1

Z96.1 is the ICD-10-CM diagnosis code for presence of intraocular lens. It belongs to category Z96 (presence of other functional implants), 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 Z96 (presence of other functional implants), Z96.1 is specifically for presence of intraocular lens. Related codes cover urogenital implants (Z96.0), otological and audiological implants (Z96.2), artificial larynx (Z96.3), endocrine implants (Z96.4), tooth-root and mandibular implants (Z96.5), orthopedic joint implants (Z96.6), other bone and tendon implants (Z96.7), other specified functional implants (Z96.8) and 1 more.

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 124 (Other Disorders of the Eye with MCC or Thrombolytic Agent, relative weight 1.2471) and DRG 125 (Other Disorders of the Eye without MCC, relative weight 0.7702), 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 not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.

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 V43.1 (lens replaced by other means).
