Background
Hattiesburg Medical Park Management Corp. and seven affiliated long-term-care providers challenged the Mississippi Division of Medicaid’s adjustments to their 2015 cost reports. The providers had reported payments received from three insurance-related entities—MHCASIF, CULIC, and LTCEIC—as other income rather than using those payments to reduce reported insurance costs. Medicaid’s adjustments lowered the providers’ prospective reimbursement rates.
The providers maintained that Medicaid had knowingly accepted this accounting treatment for decades under an unwritten internal policy. They argued that abruptly requiring offsets was arbitrary and capricious, required public notice, triggered equitable estoppel, and was particularly unfounded as to LTCEIC dividends. A hearing officer upheld the adjustments, Medicaid’s executive director adopted that recommendation, and the Hinds County Chancery Court affirmed.
The Court’s Holding
On rehearing, the Mississippi Supreme Court withdrew its prior opinions and affirmed Medicaid’s decision and the chancery court’s judgment. The court held that the providers had not established an enforceable agency policy permitting them to treat the insurance payments as nonoffsettable income. Because Mississippi’s Medicaid State Plan did not specifically address the payments, the incorporated federal Provider Reimbursement Manual governed and required returned insurance funds—including rebates, dividends, and distributions—to reduce allowable costs.
The court characterized Medicaid’s action as the correction of previously overlooked accounting errors, not a change in the State Plan or reimbursement methodology. It therefore rejected the providers’ arbitrary-and-capricious and notice arguments, concluding that an agency may correct a legal mistake even when regulated parties previously relied on it. The court also rejected the providers’ remaining challenges, including equitable estoppel and their objection to the treatment of LTCEIC payments, and upheld all disputed adjustments.
Key Takeaways
- An agency’s repeated failure to enforce an existing reimbursement requirement does not necessarily create an enforceable contrary policy.
- When Mississippi’s Medicaid State Plan is silent, incorporated federal Provider Reimbursement Manual provisions may control the treatment of provider costs and related income.
- Correcting an earlier accounting mistake is not necessarily a policy change requiring public notice, even when the agency accepted the prior treatment for many years.
Why It Matters
The decision reinforces Medicaid’s authority to correct longstanding reimbursement practices that conflict with governing written standards. Providers cannot safely rely only on past desk reviews, informal guidance, or an unwritten agency practice when the State Plan and incorporated federal reimbursement rules point in another direction.
The case also highlights a sharp disagreement within the court. The dissent viewed Medicaid’s decades-long treatment of the payments as an established policy whose reversal was arbitrary, required public notice, and lacked a sufficient basis as to LTCEIC shareholder dividends.
