What does DEA mean pharmacy?

As you may recall from the Pharmacy Law, Regulations, and Standards module, the Comprehensive Drug Abuse Prevention and Control Act of 1970 was created to combat and control drug abuse. This act also classified drugs with potential for abuse as controlled substances and ranked them into the five categories, or schedules, which you have already learned, or will soon learn. The agency made primarily responsible for the enforcement and prevention related to the abuse of these substances was the Drug Enforcement Administration (DEA).

One way the DEA tracks controlled substances is to assign a DEA number to every healthcare provider that allows them to write controlled prescriptions. The DEA number is also used to identify the prescriber. Every DEA number is made up of two letters, six numbers, and one check digit. The first letter is a code to identify the type of prescriber (i.e., a hospital, a practitioner, a manufacturer, etc.). The second letter is the first letter of the prescriber’s last name. The seven numbers follow, and the seventh is the check digit.  Let’s walk though the steps of how to verify the DEA number.

Dr. Patterson sends in a prescription with DEA number CP2756344.

Step 1:  Add digits 1, 3 and 5 = 10 Step 2:  Add digits 2, 4 and 6 = 17 x 2 = 34

Step 3:  Add the results for step 1 and 2 = 44.  The last digit of this sum should be the same as the last digit of the DEA number.

This DEA number is valid.  Let’s try another one.

Dr. Smith sends in a prescription with DEA number CC8422965.

Step 1:  Add digits 1, 3 and 5 = 19 Step 2: Add digits 2, 4 and 6 = 12 x 2 = 24

Step 3: Add the results for step 1 and 2 = 43.  The last digit of this sum should be the same as the last digit of the DEA number.

Because the last digit is 3, and because the second letter is a “C,” this would not be a valid DEA number.

With advancing technology, most likely a computer will verify the DEA number for you when you’re working in the pharmacy.  However, it’s important to know the basics of how the numbers work because you will have similar questions on the final exam and the PTCE.

A DEA number is assigned by the Drug Enforcement Administration to many types of healthcare providers, including physicians, optometrists, dentists, veterinarians, physician assistants, and nurse practitioners. The DEA number allows providers to write prescriptions for controlled substances; it is also a way for the DEA to track provider prescriptions and monitor potential fraud and abuse.

Despite COVID-19 disruptions, the DEA continues to pursue and prosecute physicians, pharmacists, and other providers for unlawful distribution of controlled substances. In March of 2021, a federal grand jury indicted the owners, operators, and two nurse practitioners of a pain management clinic for conspiracy to distribute and dispense oxycodone and for distribution and dispensing of oxycodone. Fines in this case totaled $270,000, and each participant will serve up to 20 years in prison.

Released last week, a federal court in Brooklyn, NY sentenced a pharmacy owner to 36 months in prison for the illegal distribution of over 10,000 Oxycodone pills. The defendant was not licensed to prescribe medications. These are just a couple of the many such cases in the last year.

The Drug Enforcement Administration (DEA) maintains the Controlled Substance Act Database as part of an ongoing effort to carefully regulate and monitor controlled substance prescriptions. Here’s more about the history of the DEA, the importance of the DEA number, and how Verisys uses this data to protect patients and healthcare organizations from fraud and abuse.

The Creation of the DEA

The DEA was founded in 1973 as a part of President Nixon’s War on Drugs initiative. Before the DEA, various enforcement and intelligence agencies were responsible for discovering and prosecuting drug-related crimes. The DEA was created to consolidate their work and establish one primary source for investigation and prosecution.

Today, the primary mission of the DEA is to enforce the controlled substances laws and regulations of the United States. The DEA championed several campaigns such as Nancy Reagan’s “Just Say No” campaign and Red Ribbon Week.

After Congress passed the Controlled Substances Act (CSA) in 2001, all existing regulated drugs were divided into five categories called schedules. The CSA also provided frameworks for new drugs to be added to the schedules and created the registration system for practitioners that is in use today.

Why DEA Numbers Are Important

DEA numbers allow providers to write prescriptions for controlled substances including opioids, morphine, and steroids. DEA numbers allow the DEA to monitor who is prescribing controlled substances and the quantities prescribed.

DEA numbers follow a specific format — two letters, six numbers, and one check digit — that verifies the number’s validity and reveals the prescriber. Here’s the formula:

• The first letter is a code identifying the type of registrant. This includes hospitals, physicians or practitioners, researchers, manufacturers, and others.
• The second letter is the first letter of the prescriber’s last name.
• Six digits follow the two letters.
• The seventh digit is the last digit in a formula that is as follows:

1. Add digits 1, 3, 5
2. Add digits 2, 4, 6, then multiply by 2
3. Add the numbers from step 1 and 2
4. The last digit in this formula is the check digit number

Although a computer automatically verifies the DEA number when a prescription goes to a pharmacy, providers who prescribe and dispense controlled substances should understand the makeup of a DEA number as a check against opioid abuse.

DEA numbers and the CSA database serve as primary sources to credential practitioners. HMOs, clinics, health insurance, pharmaceutical, and medical services firms all use DEA numbers to verify that a practitioner is registered to handle controlled substances.

Do All Providers Need a DEA Number?

Without a DEA number, a provider cannot prescribe controlled substances to patients; however, not all prescriptions are controlled substances. DEA numbers are unique to each provider, as described above, and they are only given to providers that have undergone the proper certification and testing, as specified by state and federal law.

While a provider could still practice without a DEA number when they’re not prescribing controlled substances, working without it is difficult. Many insurance companies and pharmacies use a DEA number as provider identification, and it has become standard. But a DEA number is not the only identifier for providers.

Differences Between DEA and NPI Numbers

According to the Centers for Medicare and Medicaid Services (CMS), “The National Provider Identifier (NPI) was adopted and became effective May 23, 2007, as the standard unique health identifier for healthcare providers to carry out a requirement in the Health Insurance Portability and Accountability Act of 1996 (HIPAA) for the adoption of such a standard.”

One of the obvious differences between an NPI and a DEA number is the agency from which they are issued: the CMS issues an NPI, and the DEA issues a DEA number.

NPIs do not replace or substitute for DEA numbers. An NPI is an identifier for a provider performing any type of HIPAA transaction so while not all providers with an NPI will qualify for a DEA number, all providers with a DEA number will have an NPI. You can, however, look up your DEA number via your NPI and check its validity.

How Verisys Identifies Fraud and Abuse of Controlled Substances to Protect Patients

When it comes to identifying fraudulent activity around and abuse of controlled substances, Verisys’ data platform goes beyond binary results from individual search queries. Verisys’ nearly 30-year-old database contains millions of provider records dating back to the 1990s. This historical and real-time aggregated database matches records to existing provider data such as aliases, addresses, work history, license history and status, data from agencies such as NPI, DEA, OFAC, and thousands of other primary sources nationwide to deliver a complete and longitudinal view of a provider or entity.

Data is valuable, but if your organization doesn’t know how to aggregate or verify the data, you will be vulnerable to risk. Initial searches upon hire and continuous monitoring of current providers are both essential to prevent controlled substance fraud and abuse that could endanger patients. Contact Verisys to find out how to keep your organization safe in an increasingly data-centric environment.
