Osteopathic physicians and surgeons: unauthorized practice: unauthorized use of titles

California will reserve osteopathic manipulation and osteopathic titles for authorized practitioners starting January 1, 2028.

The law strengthens protections against unlicensed medical treatment and misleading claims of osteopathic credentials. Violations of the new title restrictions are misdemeanors.

What the law does ​

  • Removes osteopathic manipulative treatment from the disclosure-based exception to California's unauthorized-practice-of-medicine laws.
  • Defines osteopathic manipulative treatment as manually guided therapeutic forces used to alleviate somatic dysfunction.
  • Preserves services lawfully provided by California-licensed health professionals and massage services authorized under California law.
  • Makes it a misdemeanor for an unlicensed person to use “doctor of osteopathy” or “D.O.” or to use “osteopath” misleadingly while offering treatment for a medical or physical condition.

Who it affects ​

  • Unlicensed people offering osteopathic manipulative treatment or other services to treat medical or physical conditions.
  • Osteopathic physicians and surgeons licensed by the Osteopathic Medical Board of California.
  • Patients seeking treatment marketed as osteopathic care.

Context ​

The changes take effect January 1, 2028.
