The number of Medicare beneficiaries receiving opioid prescriptions has declined significantly since 2016, according to a new government report that also found steep declines in the number of beneficiaries receiving high doses or who appear to be doctor shopping.

The report by the Department of Health and Human Service’s Office of Inspector General found that over 21 million people -- 23% of Medicare Part D beneficiaries -- received at least one opioid prescription in 2021, down from 33% of beneficiaries in 2016. Over 51 million people are currently enrolled in Part D.

The Centers for Medicare and Medicaid Services (CMS) adopted new safety rules in 2018 that discourage high dose prescribing and limit the initial supply of opioids to 7 days. The rules also allowed pharmacists and insurers to flag Medicare patients deemed to be at high risk, as well as their prescribers.

The rules appear to have had a major impact on prescribing. In 2016, over half a million Medicare beneficiaries received a daily opioid dose of at least 120 MED (morphine milligram equivalent). By 2021, that fell to less than 200,000 patients, a 60 percent decrease in high dose prescribing.   

Since 2016, the number of Medicare beneficiaries who appeared to be doctor shopping dropped from 22,300 to 1,800; while the number of doctors with “questionable” prescribing patterns fell from 401 to just 98.  Patients were flagged for doctor shopping if they were on high doses and received opioids from four or more prescribers or four or more pharmacists.

“The opioid epidemic continues to grip the nation. There is clearly still cause for concern and vigilance, even as some positive trends emerge,” the OIG report found. “The number of Medicare Part D beneficiaries who received opioids in 2021 decreased to approximately a quarter of a million beneficiaries, extending a downward trend from prior years. Further, fewer Part D beneficiaries were identified as receiving high amounts of opioids or at serious risk of misuse or overdose. The number of prescribers ordering opioids for large numbers of beneficiaries at serious risk was steady.”

But there is little evidence that less prescribing is reducing addiction and overdoses.  The Centers for Disease Control and Prevention estimates there were nearly 81,000 opioid-related deaths in 2021, nearly twice the number reported in 2016, when the CDC’s opioid guideline was released. The vast majority of deaths involved illicit fentanyl and other street drugs, not prescription opioids.

The OIG report found that 50,391 Part D beneficiaries experienced an opioid overdose (either fatal or non-fatal) in 2021, but did not break down how many were linked to illicit or prescription opioids.

Over one million Medicare beneficiaries were diagnosed with opioid use disorder (OUD) last year, but only one in five received a medication like Suboxone or methadone to treat their condition. Medicare patients were far more likely to receive naloxone, an overdose reversal drug. Over 445,000 beneficiaries received a prescription for naloxone, an 18% increase from 2020.
