Billed by or treated at a University of Maryland Medical System hospital? What to check

University of Maryland Medical System (UMMS) is a network of 11 Maryland hospitals and other care sites, so your bill, your medical record and your complaint may need to go to a specific member hospital rather than to "UMMS" generally. UMMS's own Financial Assistance Policy states that patients with income up to 200% of the Maryland Department of Health's income eligibility limits qualify for free care, and patients between 200% and 300% of those limits qualify for discounts on a sliding scale, called Reduced Cost Care. A separate "Financial Hardship" category can apply outside those limits when medical debt for medically necessary treatment at UMMS member organizations over a twelve-month period exceeds 25 percent of the family's annual income. The policy states that emergency care is provided regardless of ability to pay, and that financial-assistance applications for emergency or urgent care are handled after the fact, without delaying treatment. The application window stays open for at least 240 days after a patient's first post-discharge bill, and UMMS's policy says financial assistance should not be denied solely for missing paperwork that was not specifically required.

• Get a price estimate before non-emergency care at umms.org's Price Transparency page, or call 410-821-4140 for help understanding a price estimate, applying for financial assistance, or questions about your share of a hospital bill. Maryland's Health Services Cost Review Commission (HSCRC) sets the average hospital prices Maryland hospitals, including UMMS, may charge, twice a year (January 1 and July 1).
• For a UM Urgent Care bill, UMMS's own contact page states its billing company changed: visits before February 17, 2025 go to the prior billing company at 1 (855) 612-0087; visits on or after that date go to UMMS Billing Customer Service at 443-462-5010. These two numbers are for UM Urgent Care bills; for a UMMS hospital bill, call 410-821-4140.
• To raise a concern about your care, UMMC's own Patient Rights and Responsibilities page lists several channels: talk to your unit's Nurse Manager; contact the Patient Advocate at 410-328-8777 (or the Deaf-Friendly Videophone at 410-650-4213); contact the Maryland Office of Health Care Quality at 410-402-8016 (7120 Samuel Morse Drive, Second Floor, Columbia, MD 21046); or contact The Joint Commission (UMMC's page lists a fax number, but The Joint Commission's own complaint page now says it does "not accept faxed or emailed submissions" and takes reports online or by mail). UMMS's policy states a complaint about care will be reviewed without affecting that care.
• For a billing or insurance dispute you can't resolve directly, the Maryland Attorney General's Health Education and Advocacy Unit (HEAU) offers free mediation for medical billing and insurance disputes, including surprise bills, bills above a good-faith estimate, and denied coverage; it can also help navigate a hospital's financial assistance program. HEAU can be reached at 410-528-1840 (Spanish: 410-230-1712) or toll-free 1-877-261-8807.
• If you worked at or were treated at UMMC and think your online accounts may have been accessed without your knowledge, see the separate item below on the Matthew Bathula case; the U.S. Attorney's office has pursued federal charges over that conduct.
• For a privacy concern about your health information, UMMS's Notice of Privacy Practices directs complaints to the UMMS Privacy Officer, 900 Elkridge Landing Rd, Ste 120, Linthicum Heights, MD 21090, phone 410-328-4141, email [email protected]; you may also complain to the U.S. Department of Health and Human Services Office for Civil Rights (1-877-696-6775, hhs.gov/hipaa/filing-a-complaint). UMMS states it will take no retaliatory action against a patient who files a privacy complaint.
• For a complaint about hospital charges, financial assistance or a medical-debt payment plan, Maryland's Health Services Cost Review Commission, which says it has jurisdiction over those issues, accepts patient complaints at [email protected] (main line 410-764-2605). The Maryland Office of Health Care Quality accepts care complaints through its online complaint form, including anonymous complaints.

Company background

University of Maryland Medical System Corporation traces to the 1823 Baltimore Infirmary, which became University of Maryland Hospital; UMMS itself was formed in 1984, when the Maryland General Assembly privatized that hospital (Chapter 288, Acts of 1984), turning it into University of Maryland Medical Center under a new private, nonprofit corporation, which was reformed as University of Maryland Medical System Corporation in 1996. UMMS's own historical timeline states it "celebrates its 40th anniversary" in 2024. UMMS describes itself as an academic, private health system that works in partnership with the University of Maryland School of Medicine and University of Maryland, Baltimore, and says it "is an integrated network that delivers 25 percent of all hospital care in the state." It operates 11 hospitals — including flagship University of Maryland Medical Center in downtown Baltimore, UMMC Midtown Campus, UM Baltimore Washington Medical Center, UM Capital Region Health, UM Charles Regional Medical Center, UM Rehabilitation & Orthopaedic Institute, UM St. Joseph Medical Center, UM Shore Regional Health, UM Upper Chesapeake Health, and Mt. Washington Pediatric Hospital — plus a network of UM Urgent Care centers and more than 150 other locations across 13 Maryland counties. UMMS's CEO since 2019 is Dr. Mohan Suntha, according to UMMS's own history page; a 2020 nonprofit-hospital report separately lists a 2018 "President and CEO, UMMC" payment to "Mohanakumar Suntharalingam," and a prior UMMS President and CEO, Robert A. Chrencik, appears repeatedly in that same 2014-2018 pay data (for example, $6,902,166 in 2015 and $4,265,077 in 2017). UMMS is headquartered at 250 W. Pratt Street, Baltimore, MD 21201, per its own website footer.

UMMS filed suit in the Circuit Court for Baltimore City on June 16, 2025 against Maryland Physicians Care MCO (MPC), a Medicaid managed-care organization owned by four nonprofit Maryland hospital systems, seeking more than $15 million for services to more than 15,000 patients. UMMS's complaint, per its own press release, alleges MPC "engaged in longstanding, ongoing, deliberate, and systematic practices of denying timely and complete payment for covered medical services provided to MPC Members by UMMS," including emergency visits, COVID-19 treatment, and care for premature infants. The Baltimore Banner described this as an unusual move for a Maryland hospital system, since Maryland hospitals, including UMMS, have historically pursued unpaid bills from patients directly rather than suing insurers.

Complaint record: USAComplaints, BBB, Trustpilot, and CFPB, reported separately

Several sources track complaints and reviews about UMMS, and this page reports each separately rather than blending them into one figure:

• USAComplaints: 0 complaints submitted about University of Maryland Medical System, University of Maryland Medical Center, UMMS, or UMMC on this site as of September 28, 2026 (checked against post offender fields, titles, and common name variants).
• BBB: University of Maryland Medical System is not BBB accredited, with a BBB Rating of A+. BBB shows 1 complaint in the last three years (1 closed in the last 12 months) and 0 customer reviews. The one published complaint (dated March 3, 2026, a billing dispute over a $523 charge for a June 2024 annual visit) was answered by UMMS, whose business response states the balance was reviewed and adjusted to zero, with no further payment due from the patient.
• Trustpilot: an unclaimed profile for umms.org showing 0 reviews as of the date checked.
• CFPB: a live search of the CFPB Consumer Complaint Database's own company-name lookup for "University of Maryland" returned no matching company, so no CFPB complaint data is reported for UMMS; UMMS is a healthcare provider rather than a CFPB-regulated financial company, which may explain why it does not appear as a lookup match.

Because each source covers a different population, time window, and methodology, none of these figures is added to or averaged with any other.

The Matthew Bathula case, a website-tracking privacy suit, and other litigation

All of the following are allegations from filed complaints or an indictment, not proven facts, except where a court order or other disposition is noted.

United States v. Bathula (D. Md., No. 1:26-cr-00159, filed May 1, 2026) is a federal criminal case against Matthew Bathula, 41, of Clarksville, Maryland, a former UMMC pharmacy clinical specialist, not against UMMS itself. According to the U.S. Attorney's office (as reported by outlets including HIPAA Journal and the Baltimore-County news site NottinghamMD.com, both quoting the same Department of Justice release), Bathula's conduct spanned July 2016 to September 2024, and between February 2023 and July 2024 he allegedly installed spyware and video-surveillance software on UMMC computers, using keylogging, stolen browser cookies, file masquerading, and mailbox rules that automatically deleted security alerts to avoid detection. The FBI's Baltimore Field Office identified 195 victims nationwide after a four-month investigation, with compromised accounts including Google Photos, iCloud, Gmail, Microsoft 365, dating apps, social media, and home security systems. Bathula faces two counts of unauthorized access to a protected computer and one count of aggravated identity theft; U.S. Attorney Kelly O. Hayes called the alleged conduct "a reprehensible invasion of privacy." UMMC's own statement, quoted by HIPAA Journal, said it was "deeply disappointed and angered" by the conduct, calling it "counter to every single value we stand for." The Maryland State Board of Pharmacy lists a summary suspension of Bathula's pharmacist license dated June 12, 2025, in its disciplinary-actions list. Bathula pleaded not guilty to each count at his arraignment on May 1, 2026 and requested a jury trial; as of the docket's latest entries (August 2026), no trial date, plea agreement or conviction was recorded.

Separately, six current and former UMMC employees (proceeding as Jane Doe 1 through 6) sued University of Maryland Medical System Corporation and UMMC in the Circuit Court for Baltimore City (Case No. C-24-CV-25-002505), filed on or about March 27, 2025 and amended to seek class status on April 2, 2025. The complaint alleges Bathula installed spyware on roughly 400 UMMC devices and obtained credentials belonging to at least 80 staff members, and that UMMC knew of the misconduct since at least September 2024. The defendants removed the case to federal court on January 22, 2026 (D. Md. No. 1:26-cv-00275); it has been stayed since February 23, 2026, most recently to October 8, 2026. This civil case is separate from the federal criminal prosecution, and no ruling on the merits was found as of September 28, 2026.

Doe v. The University of Maryland Medical System Corporation was originally filed in the Circuit Court for Baltimore City (Case No. 24C23000574) and removed to the U.S. District Court for Maryland (No. 1:23-cv-00690). The complaint, filed by "Jane Doe" on behalf of a putative class, alleges UMMC's websites embedded Meta Pixel, Google Analytics, and Google Tag Manager (the tools named in the federal remand order) tracking tools that captured and shared patients' location, medical concerns, search queries, provider information, IP addresses, and Facebook IDs with Facebook, Google and other third parties without consent, allegedly contrary to UMMS's privacy policy. On November 13, 2023, U.S. District Judge Richard D. Bennett granted the plaintiff's motion to remand the case back to the Circuit Court for Baltimore City — a ruling on venue, not on the merits. No further disposition has been verified in the sources checked.

Maryland Physicians Care MCO (Circuit Court for Baltimore City, filed June 16, 2025) is the Medicaid-claims lawsuit UMMS itself filed as plaintiff, described above under Company Background; after MPC removed it to federal court, the case was remanded to state court on March 18, 2026, without a ruling on the merits.

Is University of Maryland Medical System Legitimate?

University of Maryland Medical System Corporation is a real, operating private nonprofit health system formed in 1984, headquartered at 250 W. Pratt Street, Baltimore, MD 21201, operating 11 hospitals and more than 150 other care locations across Maryland in partnership with the University of Maryland School of Medicine. It is not BBB accredited but carries a BBB Rating of A+, with 1 complaint in the last three years and 0 customer reviews on BBB and on Trustpilot; USAComplaints has 0 posts about it as of September 28, 2026. Separately, UMMS and UMMC are named as defendants in civil litigation described above — a civil suit by employees over the alleged cyber-spying scheme and a website-tracking privacy class action that was remanded to state court in 2023 — while a former UMMC employee, not UMMS or UMMC, was federally indicted over that alleged scheme; and a 2020 report found Maryland hospitals, including UMMS-affiliated ones, had filed large numbers of medical debt lawsuits against patients from 2009 to 2018, a practice more recent reporting says Maryland hospitals have largely moved away from. This page assigns UMMS no rating, score, or "scam" label of its own; readers can weigh the record above for themselves.
