In April 2021, Express Scripts stopped covering low-volume bowel preparations in its National Preferred Formulary, a move that had the potential to affect many of the 75 million Americans covered by that pharmacy benefit manager’s programs, according to the American Society for Gastrointestinal Endoscopy (ASGE).
For gastroenterologists and their patients, it was an action that added insult to injury. The COVID-19 pandemic had already led to shortages of various preps, causing many thousands of Americans to forego colonoscopies. One study estimated that there was a 95% decline in weekly colorectal cancer screenings in the first half of 2020.
Just as screenings were returning to prepandemic levels, the Express Scripts coverage change threatened to create a new barrier for those already hesitant, especially since the prep is what patients most loathe about colonoscopy, said the gastroenterologists interviewed for this story.
Almost a year later, not much has changed. or instituting higher copays.
Gastroenterologists are having to delay procedures and patients are canceling appointments; some never return.
“I and many of my colleagues are very concerned that we are going to see an increase in advanced colon polyps and colon cancer,” said Jennifer A. Christie, MD, professor of medicine in the digestive diseases division at Emory University School of Medicine, Atlanta, and vice president of the ASGE.
Obstacles to getting the right prep “not only [delay] the care, but the negative outcomes could be horrible,” agreed Tauseef Ali, MD, clinical assistant professor at the University of Oklahoma and a member of the American College of Gastroenterology’s board of governors.
For the majority of patients, a wait might not be an issue, said Christian Stevoff, MD, assistant professor of medicine at Northwestern University Feinberg School of Medicine, Chicago. But a delayed diagnosis would be significant for those with larger polyps or cancer in the colon, he said.
“It’s a major problem for those people that it does affect,” Dr. Stevoff told this news organization.
He noted that his practice had to delay around 3,000 procedures in 2020, and while they have since caught up, approximately 25% of cases are being delayed right now for a variety of reasons. Most of those are in patients deemed to be low risk, though, he said.
PBMs: ‘a parasitic infection to our health care system’
Shortages of preps have been a persistent headache, but restrictions such as those instituted by Express Scripts have become a bigger problem, said some gastroenterologists.
Express Scripts did have several exceptions to its prohibition on coverage of low-volume preps. First, it could be approved if the patient had failed with a polyethylene glycol (PEG)–based prep like GoLYTELY. It could also be approved if the patient had tried MoviPrep and failed, if MoviPrep was unavailable, or if the patient has phenylketonuria or glucose-6-phosphate dehydrogenase deficiency.
Cigna-owned Express Scripts is one of three PBMs – along with CVS Caremark and OptumRX (owned by UnitedHealth Group) – that control 85% of prescription drug benefits in the United States, according to a 2019 investigation of the industry by the New York State Senate.
Express Scripts did not return requests for comment on its bowel prep coverage, and CVS Caremark declined to participate. A spokesperson for OptumRX told this news organization that the PBM provides bowel preps at “$0 cost-share” but only for health plan sponsors that are subject to Affordable Care Act regulations that require providing colonoscopies under such a payment structure. The company did not provide further information.
For some gastroenterologists, the anger toward PBMs is palpable. Dr. Ali calls PBMs “a parasitic infection to our health care system.”
“Keeping track of these bowel prep coverages has become a nightmare,” he said, noting that every payer seems to have its own preferred prep. “We have a dedicated nurse whose only job is to keep tabs on this, and she’s unable to because it’s just getting out of control.”
Some preps are contraindicated for patients, Dr. Ali said. Yet even in those cases, it’s difficult to get the alternatives covered. It often comes down to a joint effort by a pharmacist, the patient, and Dr. Ali’s office staff to get coverage for a medically necessary prep.
If it’s an emergency, Dr. Ali said, “either our patients bite the bullet and pay the price, or we have to come up with alternative solutions that may not lead to an optimal bowel preparation. It defeats the whole purpose of having a good bowel preparation and giving them a good outcome.”
He added that “there are a lot of patients who cancel their colonoscopies out of frustration,” because the bowel prep is not available or too expensive and that some patients choose to simply not reschedule.
Dr. Christie’s experience is similar. Sometimes patients must be rescheduled because “we could not get the prep in a timely fashion for them to be ready for their procedure.” Bringing back patients can be hard: They are busy, or they can’t get a ride, or time off work, or coverage for caregiving, she said. Ultimately, “some patients do decide to either defer or decline screening.”
The hassles also have the potential to exacerbate existing health disparities, she added.
Dr. Stevoff, the gastroenterologist at Northwestern, said cancellations are a concern, but to his knowledge, none of his patients have quit in frustration.
He said that because “most of the [preps] are equivalent to each other,” he often gives preference to what’s available.
He does tell patients that they may have a higher copay. For some that may be fine for what is only a once every 5- or 10-year payment. For others who cannot afford the cost, it may mean spending time trying to convince the insurer to pay for a prep that is not normally covered, he said.
