DES MOINES — More than a quarter of Iowa Medicaid patients had their personal data compromised in a data breach affecting one of Iowa’s two Dental Wellness Plan managed care organizations.
The personal information of approximately 233,000 Iowa Medicaid members was included in a data breach of MCNA Dental earlier this year, according to the Iowa Department of Health and Human Services. It is among the largest medical data breaches in Iowa to date, according to federal data, and the largest involving Iowa Medicaid.
MCNA Dental, one of the largest dental insurers for government-sponsored Medicaid and CHIP programs, suffered a ransomware attack between February and March that led to unauthorized access to personal health data of nearly 9 million people, according to a filing with the Maine Attorney General.

MCNA Dental managed dental coverage under Medicaid for more than 295,000 Iowans as of the end of last year, according to a report from Iowa HHS. Delta Dental is the other managed care organization in Iowa’s dental program. It managed 486,000 Dental Wellness Plans.
The Iowa Department of Health and Human Services did not respond to a request for comment by the time of publication.
What information was taken?
The hackers potentially obtained a trove of data from the managed care organization, including full names, addresses, phone numbers, Social Security numbers, driver’s license numbers, health insurance plan information, bills and insurance claims, according to a notice provided to affected patients.
The attack happened between February 26 and March 7 of this year, and MCNA Dental sent notices to patients and states impacted on May 26.
The Russia-linked ransomware organization LockBit took credit for the attack, and has claimed on its dark web site to have published 700 GB of patient data from MCNA, according to TechCrunch.
Who is affected?
More than 233,000 Iowans whose Medicaid dental coverage was managed by MCNA were affected. Those impacted received a notification in the mail. Names of parents, guardians or guarantors may also have been taken.
MCNA is offering free credit monitoring and identity protection services to affected individuals.
In an emailed statement, MCNA Dental said it is committed to protecting patients’ information and maintaining the integrity of its systems.
“As soon as we discovered recent unauthorized activity affecting our network, we took steps to mitigate the risk and reported the matter to law enforcement and customers,” the company said. “We are notifying those whose information may have been involved in this incident, and we continue to fortify our systems, as appropriate, to minimize the risk of a similar incident in the future.”
Event follows other cyber incidents
The security breach is among three reported this year by Iowa HHS affecting Medicaid members. On April 10, the Iowa Department of Health and Human Services reported more than 20,000 Iowans had their data breached in an attack on an Iowa Medicaid subcontractor, Independent Living Systems.
In May, Iowa HHS reported Amerigroup accidentally disclosed personal health information for 8,333 Iowa Medicaid members to providers in explanation of payment notices.
Also in May, the Clarke County Hospital reported it had been the victim of a ransomware attack which led to the potential exposure of thousands of patients, including their names, Social Security numbers and driver’s license numbers.
While Narcan can reverse opioid overdoses in the short term, these two treatments can help patients overcome addiction altogether
While Narcan can reverse opioid overdoses in the short term, these two treatments can help patients overcome addiction altogether
Substance use disorder has reached a crisis point in the United States. The Department of Health and Human Services’ Substance Abuse and Mental Health Services Administration found in its most recent annual National Survey on Drug Use and Health, reporting on the calendar year 2021 and released in January 2023, that 17% of adults met the DSM-5 criteria for having a substance use disorder. Some 5.3 million adults struggled with opioid use disorder, specifically, according to the report.
People suffering from substance use disorders must overcome countless obstacles when pursuing treatment, among them a societal stigma that, to this day, stems from obsolete 20th-century messaging that characterized addiction as a moral failure. Such judgments have widely persisted despite counterevidence and opposition from professionals in addiction research.
The medical community has long recognized that addiction is a disease of the brain that can begin and progress due to circumstances beyond the affected individual’s control, including biology, genetics, and environment. But stigmatization keeps many sufferers trapped in a cycle progressively damaging to their health and well-being. Moreover, while treatment options include everything from self-help groups to inpatient rehabilitation, less than 10% of those in need of treatment received it in 2021.
The recent Food and Drug Administration approval of naloxone nasal spray as an over-the-counter medication is expected to reverse the effects of opioid overdoses and reduce the number of related overdose deaths, but it won’t help someone struggling to overcome addiction itself. For that, many have found success with two medications long employed for the treatment of opioid use disorder: methadone and buprenorphine. The two drugs are not identical, and their differences can have a significant effect on the recurrence of heavy substance use and a person’s ability to treat their addiction successfully.
Citing medical journals, studies, and government resources such as the Drug Enforcement Administration and Centers for Disease Control and Prevention, Ophelia highlighted the differences between methadone and buprenorphine in treating opioid use disorder.
Methadone has been in use decades longer than buprenorphine
In 1937, German chemical company I.G. Farbenindustrie developed methadone as an alternative painkiller to opium. While the full scale of World War II had yet to come, the country was nonetheless facing an opium shortage due to its trade routes remaining under the control of Allied forces.
Shortly after the war’s end, in 1947, Eli Lilly and Company introduced methadone (under the name Dolophine) to the United States for analgesic pain relief. In the 1950s, researchers at the Narcotics Farm in Lexington, Kentucky, began studying the drug for its potential in treating opioid use disorder. Two decades later, in 1973, the drug received formal authorization from the FDA as a treatment option for several opiate-based substance use disorders.
Conversely, buprenorphine was not authorized for therapeutic use in the United States until 2002, more than three decades after British researchers first developed it in a quest to synthesize a powerful but nonaddictive pain reliever.
While both are effective, the overdose risk of buprenorphine does not increase with higher doses
Treatment protocols for opioid use disorder incorporating either methadone or buprenorphine are significantly less likely to induce alternative substance misuse than abstinence-based treatment approaches. However, those treated with methadone tend to have higher rates of ongoing substance use than those treated with buprenorphine.
Neither medication will produce a “high,” but because methadone is a full opioid agonist, while buprenorphine is a partial opioid agonist, the opioid effects from methadone continue to increase with larger doses. Conversely, the opioid effects associated with overdose from buprenorphine plateau once a certain threshold is reached, regardless of whether more is taken.
Some formulations of buprenorphine include naloxone as an additional misuse deterrent. Because naloxone is an opioid antagonist—blocking opioid receptors before they can activate within the body—such formulations induce immediate withdrawal-like symptoms, rapidly reversing the effects of opioid overdoses. The immediacy of withdrawal can be physically unpleasant; consequently, treatments that employ a buprenorphine-naloxone combination act as a deterrent to the misuse of such treatments.
While methadone is more tightly regulated, buprenorphine can be prescribed for at-home use
Given the aforementioned differences between buprenorphine and methadone, it is unsurprising that methadone is more strictly regulated and less easily accessible. Methadone is considered a Schedule II substance under the Controlled Substances Act and may only be dispensed at a licensed clinic. Doctors in the US may not issue prescriptions for methadone to patients to treat opioid use disorder.
Conversely, buprenorphine is a Schedule III substance. It is legal for doctors, nurses, and other health practitioners who have obtained a DEA license to prescribe the medication to patients to pick up at a local pharmacy for at-home use. In the past, prescribers had to obtain a Data Waiver in order to prescribe buprenorphine; however, that requirement was dropped via legislation that took effect in early 2023.
