NOTE. Use of standard logistic regression: >1 odds ratio represents the increased likelihood of the outcome within the non-reference group, relative to the reference group. <1 odds ratio represents the decreased likelihood of the outcome within the nonreference group, relative to the reference group.
BMI, body mass index; IKDC, International Knee Documentation Committee; PT, physical therapy; ref, reference.

Explanation of Benefits and Limits for Medicaid Insurance Coverage in Illinois and Indiana
| Location | Physical Therapy Covered? | Copayment Required? | Limits on Services |
|---|---|---|---|
| Illinois | Yes | No | Previous authorization always required. |
| Indiana | Yes | No | Previous authorization required unless ordered by physician before hospital discharge. 12 hours/30 days or 30 therapy session/month in combination with other therapy providers. |
CPT, Current Procedural Terminology; HIP, Healthy Indiana Plan.
Previous authorization is currently waived for outpatient therapy visits due to the coronavirus disease 2019 pandemic.
HIP Basic (coverage under Indiana’s Section 1115 waiver) has a $4 copay.
HIP Basic (coverage under Indiana's Section 1115 waiver) has a combined visit limit of 60 per year. HIP Plus has a combined visit limit of 75 per year.
