Running a lab in rural Mississippi isn’t easy. You’re trying to accommodate communities that have nowhere else to turn at a time when Medicare rules aren’t much more favorable. And here’s the most frustrating part: even a single coding error can result in revenue loss that disrupts your cash flow for weeks.
However, your lab can prevent that if you understand the Novitas reimbursement caps. This resulted from an important move when Congress hit pause on the worst of the cuts for this year. But, as 2027 begins, Congress may announce reimbursement cuts. Here, we’ll discuss the best financial strategy to manage this situation and how getting Mississippi laboratory billing services helps you streamline your revenue cycle.
Novitas Solutions is the Medicare Administrative Contractor, or MAC, for Jurisdiction H, which covers seven states, including Arkansas, Colorado, Louisiana, Mississippi, New Mexico, Oklahoma, and Texas.
Novitas has held this contract since 2012 and was just re-awarded the Jurisdiction H contract again in June 2026, so it’s managing claims for labs. Every clinical laboratory test your Mississippi facility bills to Medicare flows through Novitas’ coverage policies, coding rules, and payment schedules. It’s important to follow Novitas’ policy updates, so you don’t miss out on important changes that impact your revenue cycle.
On February 3, 2026, President Trump signed the Consolidated Appropriations Act (CAA), 2026, into law. Section 6226 of that bill gave laboratories a much-needed breather by delaying the next round of Clinical Laboratory Fee Schedule (CLFS) payment cuts under the Protecting Access to Medicare Act (PAMA).
It means that CMS doesn’t reduce CLFS payments in 2026 and labs are safe this year, but a 15% reduction is expected in 2027. And it’s expected to reduce each year by 15% in 2028 and 2029.
For a rural Mississippi lab, it’s a huge financial hit. It could be the difference between staying open and shutting your doors.
The PAMA window runs from May 1 through July 31, 2026.
Under the updated timeline, applicable laboratories must report private payer rate data collected between January 1, 2025, and June 30, 2025. This data feeds directly into how CMS calculates the weighted median rates used to set your future CLFS payments.
For smaller and rural labs, it isn’t optional, and it isn’t a task that you can perform any day. If your lab meets the definition of an applicable laboratory (which, generally, means you received more than a threshold amount of Medicare revenue from CLFS and Physician Fee Schedule services in the prior period), you’re obligated to report.
And that’s important because labs underreported, due to which original PAMA rates hugely impacted rural and hospital outreach labs back in 2018. When only a few labs report, the resulting median calculates the data based on only those labs that showed up. And these are mostly large national reference labs. That’s bad news for smaller, independent, and rural facilities.
If your lab meets the applicable laboratory requirements, you must register with CMS, pull private payer and volume data from January to June 2025, cross-check your figures against the CMS reporting template, and report your findings before the July 31, 2026 deadline.
Novitas revises its LCDs and billing and coding articles on a rolling basis for Jurisdiction H, and molecular and genetic testing categories see the most frequent activity. Two important policies for Mississippi labs are:
Novitas and other MACs roll coding article changes out on a quarterly cycle, tied to the CPT and HCPCS code updates CMS releases throughout the year. That’s exactly a policy that was in practice the previous quarter can trip up your claims this quarter if you’re not following up with the update logs.
To put it simply, your claim bounces back denied. Then your staff has to find the denial reason, correct the code or documentation, and resubmit or appeal. Multiply that across dozens of claims a month, and it’s a serious cash flow drag. For a lab running on thin margins, it isn’t a feasible solution.
Mississippi’s rural healthcare landscape is under real strain. According to a PBS News article from 2022, Mississippi state health officials stated that more than half (54%) of the state’s rural hospitals were at risk of closing, and Mississippi has lost inpatient care at more rural facilities than nearly any other state since 2010. The situation worsened in the coming years. In 2025, the Governor of Mississippi, Tate Reeves, reported that seven of the state’s counties don’t have a single hospital and residents lack patient care.
Recent industry tracking also found Mississippi has one of the highest shares of rural hospitals operating in the red across the entire country, and non-expansion states like Mississippi consistently lag behind expansion states on operating margins. When the hospital struggles, the lab attached to it struggles right along with it.
This scenario doesn’t get any better if there is a Technical Component versus Professional Component (TC/26) modifier mix-up on the Mississippi Locality 00 fee schedule. It can wipe out the margin on an entire batch of tests in one swoop.
Handling Novitas’ modifier rules, the Mississippi Locality 00 fee schedule, and quarterly CPT updates in-house is a full-time job, along with the regular duties you perform in your lab. Partnering with a lab RCM specialist, such as TransLabs, solves that issue. These billing teams don’t just closely observe the updates, but also implement them in daily RCM workflows, making sure that you submit compliant and clean claims that get approved. It also frees up your internal team to focus on patient results instead of watching for and fixing claim denials.
Mississippi’s rural laboratories have a narrow window to get their revenue cycle in order before the 15% reductions start rolling in for 2027 through 2029. Between PAMA reporting deadlines, ever-changing Novitas LCDs, and the razor-thin margins rural facilities already operate on, there’s no room left for guesswork.
The labs that come out ahead are those that tighten their billing accuracy, stay on top of every coding update, and partner with RCM specialists. Now is the time to get that foundation solid, before 2027 shows up uninvited.
