Acupuncture Establishes Itself as a Pain Therapy in Mainstream American Medicine

A report published in January 2026 by the University of Washington Medicine news service (UW Medicine) provides a comprehensive portrait of a shift that has consolidated over the past decade in the United States: acupuncture has definitively left the space of so-called “alternative therapies” to become a standard component of pain services in U.S. hospitals and integrated clinics. The article contextualizes this transition through three converging forces: the opioid crisis, the maturation of the body of scientific evidence, and the expansion of coverage by public and private health plans.

The American trajectory is particularly relevant for the Brazilian context, where recently approved professional regulation (Law 15,345/2026) signals a similar movement toward integration of medical acupuncture into the health system — with the difference that, in Brazil, acupuncture has been recognized as a medical specialty by the Federal Council of Medicine (CFM) since 1995.

The opioid crisis as catalyst

The central context of the report is the devastation caused by the opioid epidemic in the United States. With more than 80,000 overdose deaths recorded in 2021 and figures that remained alarming in the following years, the crisis forced a systemic re-evaluation of how chronic pain is approached in the country. The Centers for Disease Control and Prevention (CDC) began to recommend explicitly that non-pharmacologic options be maximized before resorting to opioids — and acupuncture is cited in those guidelines as one of the alternatives with evidence of efficacy.

In parallel, the American College of Physicians (ACP) included acupuncture among the non-pharmacologic options recommended as first choice for chronic low back pain in its clinical guidelines — alongside superficial heat, massage, tai chi, and mindfulness-based cognitive behavioral therapy — recommending these interventions before opioid analgesics. This recommendation, based on high-quality systematic reviews, marked a milestone in the institutional legitimization of acupuncture within American evidence-based medicine.

Medicare coverage: access and standardization

On January 21, 2020, the Centers for Medicare and Medicaid Services (CMS) announced the decision to cover acupuncture for Medicare patients with chronic low back pain. The policy covers up to 12 sessions of acupuncture in a 90-day period, with the possibility of 8 additional sessions if the patient demonstrates clinical improvement — totaling up to 20 annual sessions. This decision was explicitly linked to the strategy of confronting the opioid crisis, seeking to offer non-pharmacologic alternatives for one of the most common chronic pain conditions.

A relevant aspect of Medicare policy is the requirement of specific provider training: practitioners performing acupuncture under Medicare coverage must have formal certification in acupuncture. This standardization requirement echoes the Brazilian model, in which medical acupuncture is practiced by physicians with a CFM-recognized specialist title — a qualification standard that ensures the patient that treatment is performed by a professional with complete medical training.

Expansion into oncology and multifactorial chronic pain

The UW Medicine report emphasizes that the integration of acupuncture in the U.S. has gone beyond low back pain: most major U.S. cancer centers designated by the National Cancer Institute (NCI) already offer acupuncture for management of cancer pain, chemotherapy fatigue, post-chemotherapy nausea, and treatment-induced peripheral neuropathy. This expansion reflects the accumulation of meta-analytic and RCT evidence documenting the efficacy of acupuncture in these conditions, reinforced by favorable safety in fragile populations such as cancer patients.

For chronic musculoskeletal pain in general, the individual patient data meta-analyses of the Acupuncture Trialists’ Collaboration — with more than 18,000 participants — established, with moderate-to-high certainty of evidence, the superiority of acupuncture over sham and no-treatment controls for low back pain, neck pain, osteoarthritis, tension-type headache, and migraine. These results provided the evidence base for ACP and CDC recommendations.
