Low vision · Rehabilitation
Low Vision Rehabilitation building the service around function.
Vision rehabilitation helps people with permanent vision loss do the things they care about. The eye doctor examines, prescribes devices and refers; occupational therapists, orientation and mobility specialists and other professionals train the patient to use what remains. This guide lays out that team and the Medicare framework behind it.
Quick answer
Evaluate, equip, refer, follow up.
A low vision service runs on four steps: a functional evaluation built around the patient's goals, a device trial and prescription, referral to rehabilitation professionals, and follow-up as the disease changes. CMS has stated since 2002 that Medicare beneficiaries with vision impairment are eligible for physician-prescribed rehabilitation on the same basis as other conditions.
Key takeaways
- Vision rehabilitation teams can include occupational therapists and orientation and mobility specialists.
- Medicare covers rehabilitation when clear goals are set and significant improvement is expected.
- Maintenance therapy is not covered under the CMS memorandum.
- Evaluations by occupational or physical therapists cannot be done by their assistants, per CMS.
- People can also seek vision rehabilitation services on their own, the NEI notes.
Who does what.
Roles drawn from NEI, AOA and CMS descriptions.
Eye doctor
Diagnoses the cause of vision loss, measures function, prescribes optical and electronic devices and writes the rehabilitation referral.
Occupational therapist
Evaluates daily living and builds a plan of care for safe, independent living, per the CMS memorandum.
Orientation and mobility
Teaches safe travel at home and in the community.
Teacher of the visually impaired
Supports children and students, one of the additional services the AOA lists.
Assistive technology specialist
Sets up screen readers, magnification software and other technology.
Social worker or counselor
Helps with adjustment, benefits and community resources, also listed by the AOA.
A five-step service flow.
How a primary care practice can run low vision care without a separate clinic.
| Step | What happens | Who |
|---|---|---|
| Identify | Flag patients whose best-corrected vision limits daily tasks | Any doctor or technician |
| Evaluate | Goals, acuity, contrast, fields, lighting and glare | Eye doctor |
| Trial and prescribe | Test devices on the patient's own tasks | Eye doctor and trained staff |
| Refer | Written referral for OT, mobility or state services | Eye doctor |
| Follow up | Re-check as disease or goals change | Eye doctor |
Ask a family member to attend the evaluation. They see the daily struggles the patient may not mention, and they help the patient use devices and follow through on referrals at home.
Frequently asked questions
Does Medicare cover low vision rehabilitation?
CMS stated in Program Memorandum AB-02-078 that beneficiaries with vision impairment are eligible for physician-prescribed rehabilitation from approved professionals, on the same basis as other conditions.

Under the memorandum, rehabilitation must have clear goals and be expected to improve function significantly within a predictable time. Maintenance therapy is not covered.
Who can perform the rehabilitation evaluation?
