Women who got mammograms or bone density scans at the Mammography Center of Monterey are being told by federal regulators to get rescreened, after the Central Coast clinic lost its certification, botched an outside accreditation review, and left patients waiting weeks or months for results that in some cases never arrived at all.
The U.S. Food and Drug Administration issued a formal safety notification last Thursday, warning patients who received mammograms at the clinic on or after December 22, 2023, that their images may be unreliable and their results may never have reached them or their doctors. The alert came after the facility failed to comply with a June 22 FDA order requiring it to directly notify affected patients and referring physicians about potential image-quality defects, according to the Radiology Business report on the FDA notice. The agency said it will keep the public informed as new information becomes available.
The clinic's Mammography Quality Standards Act certificate officially became “no longer in effect” on December 22, 2025, legally barring it from performing breast imaging, per the FDA notification. That revocation followed a review by the American College of Radiology, which notified the facility on December 10, 2025 of its intent to examine its accreditation. The clinic never appealed that review, and according to Radiology Business, it botched the imaging evaluation the college had ordered.
Patients Describe Locked Doors and Lost Results
Kate D., a patient from Carmel Valley, told Radiology Business that during a visit in October 2025, she experienced poor technician assistance and inaccurate positioning during both her mammogram and a DEXA bone density scan. She said her results were never sent to her referring doctor, and she is now paying out of pocket for a second DEXA scan. The clinic's website also listed a phone number that was not in service, the outlet reported.
Terry D., a patient from Pacific Grove, reported waiting six weeks for mammography results, per the same Radiology Business account. Yelp reviewers cited in the report described showing up for scheduled appointments only to find the facility's doors locked, along with ongoing difficulty reaching the clinic or getting results back at all.
The FDA said it received multiple patient complaints about the center, and the outlet described the clinical image quality deficiencies uncovered during the accreditation review as severe. The clinic also failed to provide mammography reports to referring providers and written lay summaries to patients within the legally required 30-day window, and it failed to transfer records within 15 days of a request, per the report.
Federal Timeline Meets Local Legal Fallout
Under 21 CFR § 900.12 of the federal Mammography Quality Standards Act, certified facilities must send written lay summaries to patients and detailed reports to providers within 30 calendar days of an exam, and findings suggestive of malignancy must be communicated within seven days, according to the eCFR. The clinic is now required to submit an extensive corrective action plan to the American College of Radiology and may not legally perform mammography until further notice.
The federal fallout followed a local legal reckoning. Monterey County District Attorney Jeannine M. Pacioni filed a civil enforcement lawsuit in February against the clinic and its owner, Randeep “Rod” Singh, a United Kingdom resident and engineer by trade, alleging late mammogram reporting and illegal non-physician ownership of the practice, according to the County of Monterey. On July 2, Monterey County Superior Court Judge Susan Matcham entered a default judgment exceeding $1 million in penalties and restitution against the clinic and Singh, permanently barring them from destroying medical records or collecting past-due bills, as reported by Monterey County Weekly.
Under California Business and Professions Code Sections 2052 and 2400, non-physicians are strictly barred from owning medical practices under the state's Corporate Practice of Medicine doctrine, which requires physician ownership to prevent outside interference in clinical decisions, according to the Medical Board of California. It remains an open question how a non-physician was able to acquire and operate the facility starting in 2021 without triggering earlier oversight from state licensing boards, the Weekly's reporting notes.
Scale of the Delays and a Cancer Diagnosis Missed
County prosecutor investigations found that starting in February 2025, at least 114 women received delayed mammogram reports past the 30-day legal deadline, and as of June 2026, at least eight women had never received results for mammograms or bone density scans at all, per Monterey County Weekly's reporting.
Among those affected was Monterey artist Aimee Darby, who underwent four separate mammograms at the clinic in 2025 before learning months later that she had breast cancer. She ultimately needed a fifth scan at Montage Health because the center's earlier images were unreadable. Darby recovered following surgery and treatment, the Weekly reported.
Where Affected Patients Can Turn Now
Local healthcare system Montage Health, working with the Montage Health Foundation, set up patient financial assistance through the Sherry Cockle Fund, offering second mammograms, reimbursements, and a dedicated helpline for women affected by the clinic's shutdown, according to Monterey County Now. Affected women can call 831-658-3989 for assistance.
In its safety alert, the FDA recommended that patients contact the clinic directly to try to access their medical records, and it urged anyone who visited before December 22, 2023 to also request their mammograms and medical reports. For those unable to retrieve records, the agency pointed patients to its online MQSA facility directory or the National Cancer Institute helpline at 1-800-422-6237 to locate certified alternative providers. The FDA said another certified facility will ultimately decide whether repeat imaging or further follow-up is needed, and it warned that some patients may require repeat imaging altogether. The agency said it will continue to monitor the situation.
