assist stakeholders in managing their drug formulary more efficiently. USP, a non-profit organization develops public compendial quality standards and solutions, including two drug classification systems: the <em>Medicare Model Guidelines (MMG)</em> for Part D plans and <em>USP Drug Classification (USP DC)</em> for non-part D plans.</p> <h2><i>USP Drug Classification</i></h2> <p>The <em>USP Drug Classification (USP DC)</em> is an independent hierarchical therapeutic drug classification system designed to assist with formulary support outside of Medicare Part D, including non-Medicare and essential health benefits (EHB) drugs. The goal of the <a href="https://www.usp.org/expert-committees/healthcare-quality-committee-work-plan">USP Healthcare Safety & Quality Expert Committee</a> is to create a comprehensive classification system for use in drug formulary development or review in non-acute or outpatient care settings.

USP has developed and updated the USP Medicare Model Guidelines (MMG) since 2004, under the Medicare Prescription Drug Improvement and Modernization Act (2003), Section 1860D-4(b)(3)(C)(ii). This section includes a requirement that Part D plans cover at least two drugs in each USP Category and Class.</p> <p>The <em>USP DC </em>was created by a USP Expert Panel during the 2015-2020 cycle formed under the Healthcare Safety and Quality (HSQ) Expert Committee. The <em>USP DC</em> was initiated by stakeholder feedback to meet evolving public health needs. Over the past ten years, the <em>USP MMG</em> has been adopted in other health policy settings outside of its intended Medicare utilization. USP has received public comments and stakeholder feedback that identified the need to create an independent classification system to provide a more comprehensive inclusion of outpatient drugs, more frequent revisions, and more detailed mapping tools for implementation.</p> <p>The <em>USP DC</em> is a classification system separate from the <em>Medicare Model Guidelines (MMG)</em> and is not endorsed or funded by the CMS.</p> </div> <div class="expanded-collapsed" style="display:none">False</div> </div>  </div> <div>     <div class="paragraph paragraph--type--collapsible-content

The Subcommittee consists of academicians, practitioners, formulary experts, patient advocates, and clinicians. This Subcommittee advises the Healthcare Safety and Quality Expert Committee on issues discovered during the annual revision processes that are relevant to developing, implementing, and revising the <em>USP DC</em>.</p> <h3><strong><span style="color:#000000;">Drug Identification</span></strong></h3> <p>Drugs included in the <em>USP DC 2025</em> are identified through various sources including:</p> <ul> <li>Drugs@FDA</li> <li>RxNorm Current Prescribable Content</li> <li>Purple book: Lists of Licensed Biological Products</li> <li>Stakeholder feedback</li> <li>Publicly available prescription formularies</li> </ul> </div> <div class="expanded-collapsed" style="display:none">False</div> </div>  </div> <div>     <div class="paragraph paragraph--type--collapsible-content paragraph--view-mode--default"> <div class="collapse-title">     <h2>Guiding Principles</h2>  <span class='icon-plus'></span><span class='icon-minus' style="display:none"></span></div> <div class="collapse-content"> <p>As with the 2024 version, the USP Drug Classification Subcommittee used the following guiding principles to inform their development of the <em>USP DC 2025</em>.</p> <p><strong>Types of Example Drugs Listed</strong></p> <p>The Subcommittee's goal was to include a comprehensive list of drugs used in non-acute and outpatient care settings. This includes prescription medications patients receive from community pharmacies, specialty pharmacies, skilled nursing facilities, and infusion centers. At this time, the Subcommittee has excluded from the <em>USP DC 2025</em> most medications used in hospital-only settings, over-the-counter drugs, and medications that are not FDA-approved. Some listed drugs may have over-the-counter products as well as prescription-only dosage forms. For example, diphenhydramine is available as an over-the-counter product for oral dosage forms and prescription-only for injectable dosage forms.</p> <h3><strong>Approach to creating Categories and Classes</strong></h3> <p>The <em>USP Drug Classification</em> retains the guiding principle of the <a href="/sites/default/files/usp/document/our-work/healthcare-quality-safety/2017-02-06_final_report_uspmmg_v7_0_rev170206.pdf">Medicare Model Guidelines (MMG)</a>, to strike a balance of helping to assure patient access to the drugs that patients need with the flexibility that health plans require in offering an affordable and effective benefit.</p> <p>When creating the categories and classes, there was careful consideration to minimize the creation of categories or classes with less than three drug examples.</p> <h3><strong>Approach to Placement of Example Drugs</strong></h3> <p>Through the lens of equity and diversity, when appropriate, the <em>USP DC</em> will consider issues such as genomic status, medical conditions, race, ethnicity, disability, sexual orientation, or gender identity in drug classification.</p> <p>The <em>USP DC</em> utilizes pharmacotherapeutic evidence within the context of FDA-approved indications for placing example drugs. Many of these example drugs may have established indications and uses outside of the United States and qualities of other drug classes (pharmacology). A drug in the associated list may appear in more than one USP Category or USP Class if there is a scientifically valid and clinically meaningful patient care use.</p> <p>Combination products are placed in USP groupings distinguished by "Combinations" or "Other" under the respective USP Category. If the combination product includes an active ingredient that improves absorption or efficacy of another active ingredient, the placement will be based on the active ingredient that contributes to therapy and not the augmenting agent. For example, Amoxicillin/Clavulanate Potassium is placed in USP Class "Beta-lactam, Penicillins" based on amoxicillin and not clavulanate potassium, an augmenting agent that enhances the spectrum of activity of amoxicillin by inhibiting beta-lactamases that inactivate amoxicillin.</p> <p>Specific dosage forms/formulations/delivery systems are generally not listed but may be included in the associated list if there is a valid and clinically meaningful patient care issue addressed by these more specific factors.</p> </div> <div class="expanded-collapsed" style="display:none">False</div>
