In July, the Centers for Medicare and Medicaid Services released the 2024 Physician Fee Schedule (PFS) proposed rule on proposed policy changes for Medicare payments. The proposed rule contains 2,883 pages of proposals for physician, hospital outpatient department, and ambulatory surgery center (ASC) payments for calendar year 2024. For gastroenterologists, there was good news and bad news.
CMS proposed to decrease the RVU conversion factor from $33.8872 in 2023 to $32.7476 in 2024, which would result in a 3.36% cut to physician payment. Medicare physician payments have been cut each year for the better part of a decade, with additional cuts proposed for 2024.
According to the American Medical Association, Medicare physician payment has already declined 26% in the last 22 years when adjusting for inflation, and that’s before factoring in the proposed cuts for 2024. Physicians are one of the only health care providers without an automatic inflationary increase, the AMA reports.
AGA opposes additional cuts to physician payments and will continue to advocate to stop them. AGA and many other specialty societies support H.R. 2474, the Strengthening Medicare for Patients and Providers Act. This bill would provide a permanent, annual update equal to the increase in the Medicare Economic Index, which is how the government measures inflation in medical practice. We will continue to advocate for permanent positive annual inflation updates, which would allow physicians to invest in their practices and implement new strategies to provide high-value care.
But in some positive news from the 2024 Medicare PFS, the Hospital Outpatient Prospective Payment System (OPPS) and the ASC proposed rules include increased hospital outpatient departments and ASC payments, continued telemedicine reimbursement and coverage through 2024, and a second one-year delay in changes to rules governing split/shared visits. Specifically:
OPPS Conversion Factor: The proposed CY 2024 Medicare conversion factor for outpatient hospital departments is $87.488, an increase of 2.8%, for hospitals that meet applicable quality reporting requirements.
ASC Conversion Factor: The proposed CY 2024 Ambulatory Surgical Center conversion factor is $53.397, an increase of 2.8%, for ASCs that meet applicable quality reporting requirements. The AGA and our sister societies continue to urge CMS to reduce this gap in the ASC facility fees, when compared to the outpatient hospital facility rates, which are estimated to be a roughly 48% differential in CY 2024.
Telehealth: CMS proposes to continue reimbursing telehealth services at current levels through 2024. Payment for audio-only evaluation and management (E/M) codes will continue at parity with follow-up in-person visits as it has throughout the pandemic. Additionally, CMS is implementing telehealth flexibilities that were included in the Consolidated Appropriations Act 2023 by allowing telehealth visits to originate at any site in the United States. This will allow patients throughout the country to maintain access to needed telehealth services without facing the logistical and safety challenges that can surround in-person visits. CMS is proposing to pay telehealth services at the nonfacility payment rate, which is the same rate as in-person office visits, lift the frequency limits on telehealth visits for subsequent hospital and skilled nursing facility visits, and allow direct supervision to be provided virtually.
Split (or shared) visits: CMS has proposed a second one-year delay to its proposed split/shared visits policy. The original proposal required that the billing provider in split/shared visits be whoever spent more than half of the total time with the patient (making time the only way to define substantive portion). CMS plans to delay that through at least Dec. 31, 2024. In the interim, practices can continue to use one of the three key components (history, exam, or medical decision-making) or more than half of the total time spent to determine who can bill for the visit. The GI societies will continue to advocate for appropriate reimbursement to align with new team-based models of care delivery.
Notably, the split (or shared) visits policy was also delayed in 2023 because of widespread concerns and feedback that the policy would disrupt team-based care and care delivery in the hospital setting. The American Medical Association CPT editorial panel, the body responsible for creating and maintaining CPT codes, has approved revisions to E/M guidelines that may help address some of CMS’s concerns.

The guidelines emphasize four-hour gastric emptying studies over two-hour testing. How do you see this affecting diagnostic workflows in practice?
Dr. Staller: Moving to a four-hour solid-meal scintigraphy will actually simplify decision-making. The two-hour reads miss a meaningful proportion of delayed emptying; standardizing on four hours reduces false negatives and the “maybe gastroparesis” purgatory that leads to repeat testing. Practically, it means closer coordination with nuclear medicine (longer slots, consistent standardized meal), updating order sets to default to a four-hour protocol, and educating front-line teams so patients arrive appropriately prepped. The payoff is fewer equivocal studies and more confident treatment plans.
Metoclopramide and erythromycin are the only agents conditionally recommended for initial therapy. How does this align with what is being currently prescribed?
Dr. Staller: This largely mirrors real-world practice. Metoclopramide remains the only FDA-approved prokinetic for gastroparesis, and short “pulsed” erythromycin courses are familiar to many of us—recognizing tachyphylaxis limits durability. Our recommendation is “conditional” because the underlying evidence is modest and patient responses are heterogeneous, but it formalizes what many clinicians already do: start with metoclopramide (lowest effective dose, limited duration, counsel on neurologic adverse effects) and reserve erythromycin for targeted use (exacerbations, bridging).
Several agents, including domperidone and prucalopride, received recommendations against first-line use. How will that influence discussions with patients who ask about these therapies?
Dr. Staller: Two points I share with patients: evidence and access/safety. For domperidone, the data quality is mixed, and US access is through an FDA IND mechanism; you’re committing patients to EKG monitoring and a non-trivial administrative lift. For prucalopride, the gastroparesis-specific evidence isn’t strong enough yet to justify first-line use. So, our stance is not “never,” it’s just “not first.” If someone fails or cannot tolerate initial therapy, we can revisit these options through shared decision-making, setting expectations about benefit, monitoring, and off-label use. The guideline language helps clinicians have a transparent, evidence-based conversation at the first visit.
The guidelines suggest reserving procedures like G-POEM and gastric electrical stimulation for refractory cases. In your practice, how do you decide when a patient is “refractory” to medical therapy?
Dr. Staller: I define “refractory” with three anchors.
1. Adequate trials of foundational care: dietary optimization and glycemic control; an antiemetic; and at least one prokinetic at appropriate dose/duration (with intolerance documented if stopped early).
2. Persistent, function-limiting symptoms: ongoing nausea/vomiting, weight loss, dehydration, ER visits/hospitalizations, or malnutrition despite the above—ideally tracked with a validated instrument (e.g., GCSI) plus nutritional metrics.
3. Objective correlation: delayed emptying on a standardized 4-hour solid-meal study that aligns with the clinical picture (and medications that slow emptying addressed).
At that point, referral to a center with procedural expertise for G-POEM or consideration of gastric electrical stimulation becomes appropriate, with multidisciplinary evaluation (GI, nutrition, psychology, and, when needed, surgery).
What role do you see dietary modification and glycemic control playing alongside pharmacologic therapy in light of these recommendations?
Dr. Staller: They’re the bedrock. A small-particle, lower-fat, calorie-dense diet—often leaning on nutrient-rich liquids—can meaningfully reduce symptom burden. Partnering with dietitians early pays dividends. For diabetes, tighter glycemic control can improve gastric emptying and symptoms; I explicitly review medications that can slow emptying (e.g., opioids; consider timing/necessity of GLP-1 receptor agonists) and encourage continuous glucose monitor-informed adjustments. Pharmacotherapy sits on top of those pillars; without them, medications will likely underperform.
The guideline notes “considerable unmet need” in gastroparesis treatment. Where do you think future therapies or research are most urgently needed?
Dr. Staller: I see three major areas.
1. Truly durable prokinetics: agents that improve emptying and symptoms over months, with better safety than legacy options (e.g., next-gen motilin/ghrelin agonists, better-studied 5-HT4 strategies).
2. Endotyping and biomarkers: we need to stop treating all gastroparesis as one disease. Clinical, physiologic, and microbiome/omic signatures that predict who benefits from which therapy (drug vs G-POEM vs GES) would transform care.
3. Patient-centered trials: larger, longer RCTs that prioritize validated symptom and quality-of-life outcomes, include nutritional endpoints, and reflect real-world medication confounders.
Our guideline intentionally highlights these gaps to hopefully catalyze better trials and smarter referral pathways.
