Medical Bill Disputes in Maryland: Your Rights and Options
Maryland is the only state in America where hospitals cannot simply set their own prices. The Health Services Cost Review Commission sets the rates that all payers — including Medicare and Medicaid — must pay Maryland hospitals. If your hospital bill doesn’t match HSCRC-approved rates, that is a billing violation.

Key Maryland Consumer Protections
Maryland’s All-Payer Hospital Rate System
Maryland operates under a unique all-payer hospital rate regulation system administered by the Health Services Cost Review Commission (HSCRC). All hospitals in Maryland must charge the same rates to all payers for the same services. This system:
- Eliminates certain price discrimination that exists in other states
- Sets maximum rates that hospitals can charge
- Is approved by the federal government as a Medicare waiver
For patients, this means that the chargemaster rates hospitals charge are regulated — unlike in most states where prices vary dramatically.
Maryland’s Surprise Billing Law
Maryland has enacted protections against surprise billing, particularly for out-of-network care at in-network facilities. State law requires health plans to hold patients harmless from balance billing in specified circumstances and requires specific disclosures from out-of-network providers.
Federal No Surprises Act (2022)
The federal law applies to most Maryland patients with private insurance and provides additional protections, particularly for ERISA self-insured employer plans.
Maryland Hospital Financial Assistance
Maryland nonprofit hospitals have charity care obligations. Many Maryland hospital systems, including Johns Hopkins Medicine, University of Maryland Medical System, MedStar Health, and Luminis Health, have financial assistance programs.

How to Dispute a Medical Bill in Maryland
Step 1: Request your itemized bill. Maryland providers must supply itemized bills on request. Use our EOB decoder to review your insurance statement.
Step 2: Check for errors. Given the HSCRC rate system, check whether any hospital charges exceed the regulated rates. Also check for duplicate charges, upcoding, and balance billing. See our billing errors guide.
Step 3: Contact the provider. Send a formal written dispute to the billing department. In Maryland, citing the HSCRC rate schedule may be useful if a hospital overcharged.
Step 4: File a grievance with your insurer. Maryland-regulated plans must have internal grievance processes. File in writing and track timelines.
Step 5: Contact MIA. If the insurer does not resolve the dispute, file a consumer complaint with MIA. The administration investigates and can require corrective action.
Step 6: External review. Maryland has external independent review for denied claims. File through MIA if your internal appeal is denied.

Maryland’s Unique All-Payer Hospital Rate System
Maryland operates under the nation’s only All-Payer Hospital Rate System, regulated by the Health Services Cost Review Commission (HSCRC). Under this system — approved as a federal Medicare waiver — every payer (Medicare, Medicaid, private insurance, uninsured) pays the same HSCRC-set rate for hospital services. Hospitals cannot charge different rates to different payers for the same service.
This creates a significant protection for Maryland patients: if you receive an itemized bill, you can compare your billed charges against the HSCRC’s published rate schedule at hscrc.maryland.gov. Any amount above the approved rate is unlawful — and you can file a complaint directly with the HSCRC’s Compliance Division.
Maryland also passed HB 416 (2023), which:
- Prohibits hospitals from selling low-income patients’ medical debt to third-party debt buyers
- Requires hospitals to apply charity care before any collection activity for patients below 200% FPL
- Creates a medical debt ombudsman within the Maryland Health Benefit Exchange to assist patients with billing disputes
For state-regulated insurance plans, SB 20 (2020) enacted a comprehensive balance billing ban that mirrors and in some respects exceeds the later federal No Surprises Act.
FAQ
Q: Does Maryland’s all-payer system mean hospital bills are the same for everyone? A: Yes, for hospital services regulated by the HSCRC. All payers (Medicare, Medicaid, commercial insurers, and uninsured patients) pay the same regulated rates for regulated hospital services. This does not eliminate all billing errors but does provide a rate benchmark for disputing overcharges.
Q: What is the HSCRC and how does it help patients? A: The Health Services Cost Review Commission sets maximum rates for Maryland hospital services. If a hospital charges above HSCRC-approved rates, patients and insurers can challenge those charges. The HSCRC website publishes hospital rate schedules.
Q: Are Maryland’s surprise billing protections stronger than federal law? A: Maryland has its own surprise billing protections that may provide additional coverage beyond the federal No Surprises Act for state-regulated plans. Consult MIA to determine which law provides the strongest protection in your specific situation.
Q: How quickly must Maryland insurers respond to claims? A: Maryland requires clean claims to be paid within 30 days for electronic submissions. Late payments may trigger interest penalties under state law.
Q: Can Maryland medical providers sue me in small claims court for unpaid bills? A: Yes, but the amount limits for Maryland small claims court are relatively low. For larger debts, providers would need to use the circuit court system. You can raise billing errors and other defenses in any lawsuit. Contact Maryland Legal Aid if you are sued for medical debt.
