Prior Authorization in Mississippi

What is specific to Mississippi

Most Mississippi Medicaid beneficiaries are enrolled in MississippiCAN managed care plans, so plan-by-plan credentialing gates payment for a provider base that is heavily rural and weighted towards small independent practices.

Mississippi’s Medicaid program is Mississippi Medicaid. Practices with a meaningful Mississippi Medicaid mix usually need it worked as its own queue rather than mixed into commercial follow-up, because the submission path, the timely filing window and the appeal route are all different.

Medicare here is adjudicated by Novitas Solutions, jurisdiction JH — shared with Arkansas and Louisiana, but not with Alabama (Palmetto GBA) or Tennessee (Palmetto GBA). CMS publishes the jurisdictions; checked September 2026.

What a prior authorization seat does in Mississippi

Submitted before the date of service and chased through the payer's decision window.

An authorisation found after the visit is a write-off, not a denial to appeal. In Mississippi the work is submitting ahead of scheduling and chasing the decision, against a payment clock that starts only once a clean claim lands.

• Authorizations submitted ahead of scheduling, not after
• Status chased rather than waited on
• Peer-to-peer reviews scheduled when required
• Clinical documentation gathered before submission
• Expiring authorizations flagged before they lapse
• Worked during Mississippi business hours, not queued overnight

For the statute behind all of this — Mississippi’s prompt-pay deadline, its Medicaid filing limit, and the wrinkle that catches people out here — see the Mississippi billing page.

Mississippi Medicaid, in practice

Mississippi Medicaid applies hard countable service caps that most states do not: physician office visits are limited to '16 per fiscal year' on a state fiscal year running 'July 1 through June 30' (not the calendar year), and prescriptions are capped at '6 per month with no more than 2 of the 6 being brand name drugs.' Billers must track visit counts against a July–June year or claims deny once the cap is hit mid-treatment. Source: medicaid.ms.gov

For authorisations it decides who you ask. A carve-out means the rules, the portal and the turnaround belong to a different administrator from the one handling the rest of the member’s care, and an authorisation obtained from the wrong one is not an authorisation.

How long you have to file a Mississippi Medicaid claim

365 calendar days from the date of service. Not stated in Rule 1.6; a claim recouped by a CCO after the 365 days may be refiled within 90 days of the recoupment.

“The Division of Medicaid requires providers to submit claims no later than three hundred sixty-five (365) calendar days from the date of service.” Mississippi Division of Medicaid, Administrative Code Title 23, Part 200, Rule 1.6 Timely Filing (effective 1 January 2024)

A claim past that date is not late, it is unpayable, and no appeal recovers it. It is the one queue where a week of nobody working it is money that does not come back — which is the argument for working Mississippi Medicaid as its own queue rather than mixing it into commercial follow-up. Every state’s limit is listed here.

That date is also the outer edge of what a retrospective authorisation is worth. Payers will sometimes grant one after the fact, and practices treat that as the problem solved — but the claim still has to be filed inside the window above. An authorisation granted after it has closed is an administrative victory attached to money nobody can bill, which is why the authorisation queue and the filing clock have to be watched on the same screen rather than by two different people.

Working Mississippi hours

Mississippi runs on Central time, 11 hours behind our floor in Rawalpindi. To be at a desk for your nine to five, the shift here runs 8pm to 4am, and 7pm to 3am once the clocks go forward. Pakistan does not observe daylight saving, so the shift moves on this side rather than yours.

That is the part that decides whether follow-up happens at all: a payer’s phone lines are open on Mississippi hours and nobody else’s.

What it costs in Mississippi

$1,900

Per seat, per month, in US dollars — $22,800 a year for one full-time person, forty hours a week, on Mississippi hours. No annual contract, no percentage of collections, no setup fee and no software to buy. Seat prices across all roles in Mississippi run $1,500 to $2,500; the full list is published.

That is the entire invoice. Run your own figures against a percentage vendor or a hire rather than take ours.

About a week from a signed agreement to a person working your queue, and that week of training is not billed on top. The week, step by step, and what is signed before anyone has access.
