Most State Medicaid Programs Cover Routine Eye Exams For Adults, But Coverage Of Other Routine Vision Services Varies

Area of Science:

• Public Health
• Ophthalmology
• Health Policy

Background:

• Over 12 million US adults aged 40+ experience vision impairment, a number projected to double by 2050.
• While corrective lenses can often resolve vision impairment, access to routine eye care remains a significant barrier for many adults.
• Variability in state-level healthcare policies impacts the accessibility of crucial vision services.

Purpose of the Study:

• To analyze state-by-state Medicaid policies in 2022 regarding adult vision services.
• To identify disparities in coverage for routine eye exams, glasses, and low vision aids.
• To estimate the number of adult Medicaid enrollees lacking comprehensive vision coverage.

Main Methods:

• Analysis of detailed state-specific Medicaid policies for the year 2022.
• Documentation of coverage variations for routine eye exams, glasses, and low vision aids.
• Estimation of adult Medicaid enrollees residing in states with inadequate vision care coverage.

Main Results:

• Most fee-for-service Medicaid programs covered routine eye exams, but coverage for glasses was absent in 20 states and low vision aids in 35 states.
• Approximately two-thirds of states offering routine eye exams required cost-sharing from enrollees.
• Managed care plans generally offered consistent or better coverage than fee-for-service, though variations existed within states.
• An estimated 6.5 million and 14.6 million adult enrollees lived in states lacking comprehensive coverage for eye exams and glasses, respectively.

Conclusions:

• Significant gaps exist in Medicaid coverage for adult vision services across US states.
• Policy variations create barriers to accessing essential vision care, including corrective lenses and low vision aids.
• Opportunities exist for states to enhance Medicaid policies to improve access to routine vision care and reduce vision impairment.
