OTHER RELEVANT INFORMATION

Caveats and Limitations

ODD does not differentiate between Type I and II cases. Only includes retinal eye exams where a fee-for-service claim was submitted. Exams that were paid out-of-pocket by the patient are not included. Some providers (i.e. ophthalmologists in alternate payment plans) may not submit claims. The percent of patients receiving exams may be underestimated in areas where there are a larger proportion of non FFS providers conducting retinal eye exams
