- Board of Registration in Medicine
WAKEFIELD — At its meeting on December 4, 2025, the Massachusetts Board of Registration in Medicine took disciplinary action against the medical licenses of Steven W. Powell, M.D., Katherine Lantsman, M.D., and Howard H. Liu, M.D.
In a Consent Order, the Board revoked Dr. Steven W. Powell’s right to renew his medical license after he acknowledged that he had been convicted of one count of Health Care Fraud, and had been disciplined by the Kansas and Missouri Medical Boards for reasons substantially similar to those for which Massachusetts could impose discipline, to wit, having been convicted of a crime. The Respondent submitted more than $1.9 million to Medicare in false and fraudulent claims for durable medical equipment. Dr. Powell, a board-certified psychiatrist, was licensed in Massachusetts from March 23, 2017 until November 22, 2023.
In another Consent Order, the Board reprimanded the medical license of Dr. Katherine Lantsman after she agreed that she had practiced outside the scope of a general internist and outside of the standard of care in her treatment of three patients. She did so by using laboratories whose tests did not follow CDC criteria, by prescribing multiple antibiotics at higher than usual doses, recommending herbal regimens or nutritional supplements without adequately documenting the rationale for them and recommending second-line, off-label endocrine therapy without consulting an endocrinologist, as well as prescribing antiparasitic medication without a clear diagnosis of parasite infection. Dr. Lantsman also admitted to failing to maintain complete patient records. Dr. Lantsman is required to complete a medical education course in infectious disease and in medical record-keeping within six months. Dr. Lantsman is board certified in internal medicine by the American Board of Medical Specialties. She has been licensed to practice medicine in the Commonwealth since August 6, 2008, and currently practices medicine in a private practice in Brookline.
The Board also reprimanded the medical license of Dr. Howard H. Liu after he acknowledged, in a Consent Order, that he failed to query the Massachusetts Prescription Awareness Tool when prescribing benzodiazepines as required by law and failed to document any evaluation of clonazepam’s usefulness in a patient’s medical record. Dr. Liu is required to complete continuing medical education on proper prescribing within 90 days. Dr. Liu, a board-certified internist, has been licensed to practice medicine in Massachusetts since June 23, 1999. He has a private medical practice in Brookline, the American Chinese Medical Center, and has privileges at Beth Israel Deaconess Medical Center.
The Massachusetts Board of Registration in Medicine licenses more than 40,000 physicians, osteopaths and acupuncturists. The Board was created in 1894 to protect the public health and safety by setting standards for the practice of medicine and ensuring that doctors who practice in the Commonwealth are appropriately qualified and competent. The Board investigates complaints and determines sanctions. More information is available at www.mass.gov/massmedboard or you may contact the Board at borimmediamassmail.state.ma.us.
