Mississippi Medicaid Rates: Division of Medicaid Fee Schedules

Mississippi’s Medicaid program is administered by the Mississippi Division of Medicaid, publishing fee schedules at medicaid.ms.gov — primarily as downloadable Excel files, with a PDF version and an interactive fee lookup tool also available.

What’s currently published

Current published rates tracked by MedicaidBench:

• 90791 (initial psychiatric diagnostic evaluation): $125.93 per encounter (effective 2025-07-01)
• 90837 (individual psychotherapy, ~60 min): $118.63 per session (effective 2025-07-01)
• 97153 (ABA treatment by technician, per 15 min): $15.08 (effective 2025-12-01)

Mississippi is one of the more recently updated states MedicaidBench tracks for these specific codes, with a July 2025 effective date for its psychotherapy codes and a December 2025 effective date for its ABA code — a useful reminder that even within one state’s behavioral health category, individual codes can be on different update cycles.

Format and access

Mississippi’s dual approach — a downloadable spreadsheet plus an interactive lookup tool — is relatively provider-friendly compared to states that offer only one access method. The spreadsheet in particular makes bulk comparison across many codes straightforward, without needing to query an interactive tool one code at a time.

What to watch for

The December 2025 effective date on Mississippi’s ABA rate is notably more recent than its psychotherapy codes, suggesting the state may be actively revisiting ABA-specific reimbursement independent of its broader behavioral health fee schedule cycle — worth a dedicated alert if ABA is a significant part of your Mississippi billing.

Keeping current

Because Mississippi publishes a genuine downloadable spreadsheet, comparing versions over time is more tractable than in portal-only states — but it still requires someone to actually re-download and diff the file periodically. MedicaidBench does that continuously, so a rate change shows up as soon as it’s detected rather than at the next manual check.
