Medical Billing Services in Maryland

Maryland is the only state in the country running an all-payer hospital model — the HSCRC sets hospital rates that every payer, Medicare included, pays alike — which gives the whole ecosystem a rhythm nowhere else has, even for professional billing outside the rate-set facilities. The commercial market belongs to CareFirst BCBS, Medicaid runs through HealthChoice MCOs led by Johns Hopkins' Priority Partners, and provider enrollment lives in the ePREP portal. Maryland's prompt-pay statute puts a 30-day clock on clean claims with escalating monthly interest, and the DC-adjacent counties add the same FEHB federal-employee density Northern Virginia sees.

Maryland Medicaid (HealthChoice): filing rules that decide whether you get paid

Administered by the Maryland Department of Health (MDH)

Maryland Medicaid fee-for-service claims carry a 12-month window from the date of service, but most members are in HealthChoice managed care — Priority Partners (Johns Hopkins) holds major enrollment, alongside Maryland Physicians Care, CareFirst Community Health Plan, Wellpoint, UnitedHealthcare, Aetna Better Health and Kaiser — and MCO manuals set shorter working deadlines, commonly 180 days. Provider enrollment, revalidation and group affiliations run through ePREP, and Maryland is strict about keeping ePREP records current: lapses cascade into MCO claim rejections quickly here.

Deadlines for every major payer — including Maryland Medicaid — live in our timely filing limits tool, with an interactive deadline checker.

Maryland billing rules that move real money

Maryland prompt-pay (§15-1005)

Maryland requires carriers to pay clean claims within 30 days; late payment accrues monthly interest that escalates the longer the claim ages. The Insurance Administration takes provider complaints, and Maryland's escalating-interest design makes aged-claim documentation unusually valuable — the penalty grows with the delay.

The all-payer hospital model

The HSCRC sets Maryland hospital rates that all payers pay uniformly under the state's federal waiver — the only such system in the US. Professional fees aren't rate-set, but the model shapes everything around them: hospital-based billing, site-of-service economics and payer negotiation dynamics all behave differently in Maryland than across the state line.

Credentialing & enrollment in Maryland

Physician licensing in Maryland runs through the Maryland Board of Physicians, and payer enrollment is its own workstream on top of it — state Medicaid enrollment, CAQH upkeep, and individual plan contracting each on their own timeline.

Maryland billing FAQs

What is the timely filing limit for Maryland Medicaid?

12 months from the date of service for fee-for-service claims, but HealthChoice MCOs — Priority Partners, Maryland Physicians Care, CareFirst CHP and the rest — set shorter working limits, commonly 180 days. Bill to the plan manual.

What does Maryland's all-payer model mean for my practice?

The HSCRC sets uniform hospital rates for all payers under Maryland's federal waiver. Professional fees aren't directly rate-set, but hospital-based services, facility billing and site-of-service economics follow rules that exist nowhere else — experience with them matters.

How fast must Maryland insurers pay claims?

Clean claims are due within 30 days under §15-1005, with monthly interest that escalates as claims age. We document submission dates and demand the escalating interest on chronically late payers.

Can you manage ePREP for my group?

Yes — ePREP enrollment, revalidations and group affiliations are part of our credentialing service, and we calendar revalidations aggressively because Maryland lapses cascade into MCO rejections fast.
