    How to Report the Measure

    Numerator: 20/30 best-corrected distance visual acuity OR an improvement in best-corrected distance visual acuity achieved within 4 months following the cataract surgery:

    Eyes with mild to moderate stage glaucoma and a 20/30 or better post-operative best-corrected distance visual acuity

    AND

    Eyes with severe stage glaucoma or a pre-operative best-corrected visual acuity of 20/200 and a 2 lines or better improvement in the post-operative best-corrected distance visual acuity from preoperative visual acuity

    AND

    Eyes with a pre-operative best-corrected visual acuity of 20/400 and a 1 line or better improvement in the post-operative best-corrected distance visual acuity from pre-operative visual acuity

    Denominator Exclusions:

    • Eyes with absolute glaucoma blindness (ICD-10: H44.511, H44.512, H44.513)
    • Eyes with these visual acuity findings: Count fingers (CF or FC), Hand motion (HM), Light perception (LP), No light perception (NLP)

    Instructions: 
    This measure is to be calculated each time a procedure for cataracts and a procedure for MIGS is performed during the reporting period. This measure is intended to reflect the quality of services provided for the eyes receiving cataract surgery and MIGS on the same day.

    • Include only procedures performed through August 31 of the reporting period. This will allow the postoperative period to occur within the reporting year.

    Clinicians who indicate modifier 55, postoperative management only OR modifier -56, preoperative management only, will not qualify for this measure
