Medical Billing Services in Maryland

Maryland is the only state where a rate commission, not a negotiated contract, decides what hospitals get paid. That single fact changes how claims get coded, filed, and followed up everywhere in the state.

Nine Medicaid plans, one carrier that sets the commercial tone, and a behavioral health system billed through its own separate portal. A billing process built for other states misses all three.

The rate system

How Maryland pays differently

For decades, Maryland has run the only hospital payment system in the country where a state commission, the Health Services Cost Review Commission, sets the rate every payer pays for the same service at the same hospital. Medicare, Medicaid, commercial carriers, and self-insured employers all pay that same regulated number. The state recently moved into a new phase of that arrangement, the AHEAD Model, which folds primary care and total-cost accountability into the framework that has governed hospital rates for a long time. Hospitals operate on fixed global budgets rather than being paid by volume.

The part most billing teams miss

Rate regulation covers hospital facility charges. It does not cover professional fees. Physicians still bill under standard CPT and HCPCS logic, against the payer's fee schedule and your commercial contract terms. For provider-based departments and split or shared encounters, the facility side and the professional side answer to two different sets of rules. A claim that looks miscoded is often just filed under the wrong one.

Because Maryland hospitals work off a capped budget rather than a per-procedure incentive, more care keeps moving into ambulatory surgery centers, outpatient imaging suites, and physician offices. Each shift changes the place-of-service code, the modifier set, and sometimes the entire fee schedule a claim falls under. A billing process that doesn't track where a service actually happened keeps filing claims against the wrong site.

The arrangement between Maryland and the federal government is still being worked out in places, particularly around how much authority CMS keeps over Medicare rate-setting going forward. Practices that built their billing assumptions around the older terms should expect some of those assumptions to shift again.

The payer map

Who actually pays your claims

Four separate payer environments operate in Maryland, each with its own portal, its own rules, and its own way of denying a claim.

Medicaid

HealthChoice: nine plans, one program

Maryland runs Medicaid managed care through HealthChoice, which currently contracts with nine MCOs: Aetna Better Health, CareFirst BlueCross BlueShield Community Health Plan, Jai Medical Systems, Kaiser Permanente, Maryland Physicians Care, MedStar Family Choice, Priority Partners, UnitedHealthcare, and Wellpoint. Members move between plans. Checking eligibility at the state Medicaid level tells you almost nothing; you need to know which of the nine actually has the patient today.

Behavioral health

Paid through a separate system entirely

Mental health and substance use disorder services are carved out of HealthChoice and paid fee-for-service through the state's behavioral health administrative services organization, currently Carelon Behavioral Health. That vendor sits on both ends of a claim: it approves the authorization and it adjudicates the payment. A well-documented system-wide backlog on that platform topped 437,000 claims before it was worked down, a useful reminder of how much exposure a single-vendor carve-out creates.

Commercial

One carrier sets the commercial tone

CareFirst BlueCross BlueShield covers more lives than any other commercial plan in the state, so its medical policy and authorization rules end up shaping how most commercial claims get built. Kaiser Permanente has real strength in the DC suburbs. Johns Hopkins Health Plans, UnitedHealthcare, Aetna, and Cigna round out a market that behaves differently the moment you leave CareFirst's network rules.

Medicare

Medicare runs through Jurisdiction L

Maryland sits in Medicare Jurisdiction L, administered by Novitas Solutions, alongside Delaware, New Jersey, Pennsylvania, and the District of Columbia. Novitas local coverage determinations and billing articles govern medical necessity documentation here. A practice with a second site just across the Potomac in most of Virginia answers to a different contractor, Palmetto GBA, with its own set of rules.

A change worth planning around

Maryland Medicaid enrollment and revalidation currently run through the ePREP portal, which the state is replacing with a new system called MPRIME. If your practice has revalidations or new enrollments coming up around that changeover, it's worth sequencing them with care instead of filing at the last minute.

Where it goes wrong

Where revenue slips through the cracks

These six problems show up again and again in Maryland practices, and most of them never appear on a standard aging report.

Credentialing clocks with real teeth

Maryland's credentialing statute, Insurance Article §15-112, gives a carrier 30 days to say whether it will keep processing your application, then 120 days to accept or reject it. An incomplete application has to be returned within 10 days rather than left sitting. Practices that don't track those windows absorb months of care delivered by a provider who technically isn't on the panel yet.

Prompt pay that doesn't reach every plan

State law requires a clean claim be paid within 30 days, with interest owed automatically once a carrier misses that window. Self-funded ERISA plans and federal employee health plans sit outside that protection, since federal law preempts it. Given how many federal workers live in the DC suburbs, a meaningful share of many practices' receivables falls into that exempt category and needs a different follow-up rhythm.

Recoupments that go unquestioned

Carriers in Maryland can only claw back a paid claim within six months of paying it, extended to 18 months when coordination of benefits is involved, with no time limit at all when fraud or miscoding is the stated reason. Practices routinely repay takebacks that landed outside those windows simply because nobody checked the payment date against the recoupment date.

Telehealth billed with the wrong modifier

Maryland made payment parity and coverage for qualifying audio-only visits a permanent part of its telehealth law, for Medicaid and commercial carriers alike. Good policy still depends on correct execution: Maryland Medicaid identifies an audio-only encounter with the UB modifier, and facility, room, or board charges generally aren't reimbursed for a telehealth visit where a professional fee can be billed on its own.

Non-claims payments that never get reconciled

Practices enrolled in Maryland's primary care programs, such as MDPCP, receive care management and performance-based payments outside the normal claims stream. Those payments don't arrive on an 835, don't show up in standard AR aging, and get missed by any process built only to reconcile claims.

Cross-border patients and dual contractors

Maryland practices routinely treat patients who carry DC, Virginia, Delaware, Pennsylvania, or West Virginia coverage. That means out-of-state Medicaid enrollment, multi-state licensure questions, and, for any group with a second location in Virginia, two different Medicare contractors to answer to instead of one.

How we work

We plan around Maryland's rules before the claim goes out

We would rather catch a Maryland-specific rule at intake than find it in a denial three weeks later.

  • Facility and professional claims kept separateFor hospital-affiliated practices, we route facility charges and professional charges to the schedules that actually govern each one, so HSCRC-regulated activity never gets billed under standard professional logic.
  • Eligibility checked at the plan levelWe verify which of the nine HealthChoice MCOs, or which behavioral health vendor, is active for a patient right now, not just whether Medicaid coverage exists in general.
  • Credentialing tracked against the statutory clockWe monitor the §15-112 notice and decision windows, keep CAQH current, and sequence Medicaid enrollment around the ePREP-to-MPRIME transition instead of around our own convenience.
  • Recoupments checked against the calendarEvery takeback gets measured against Maryland's six-month and 18-month retroactive denial limits before we accept it, and appealed when a carrier goes past them.
  • AR worked in two tracksClaims that fall under the 30-day prompt pay rule are followed on that schedule; ERISA and federal employee claims, which don't get that protection, are worked earlier and more often.
  • Non-claims payments reconciled on their ownCare management and performance payments from Maryland's primary care programs are tracked separately from claims receipts, so they get counted instead of lost.

Services

Services built around Maryland's payer rules

Every service below works the way it actually has to work in this state, not in general.

Medical billing

Claims go out against Novitas Jurisdiction L edits, CareFirst's medical policy, and whichever of the nine HealthChoice MCOs is active, with Medicaid's 12-month filing window and the state's 180-day commercial filing floor tracked separately by payer.

Medical coding

Coding follows current CPT, ICD-10-CM, and HCPCS Level II, with attention to Novitas LCD diagnosis requirements, correct modifier use (including UB for Medicaid audio-only visits), and assignment that keeps pace with care moving out of the hospital.

Credentialing and re-enrollment

We manage commercial panel applications against §15-112 deadlines, Medicaid enrollment and revalidation through ePREP (and soon MPRIME), and multi-state credentialing for practices with a DC or Virginia location.

Eligibility verification

We confirm which HealthChoice MCO is active, whether the behavioral health carve-out applies, and whether a patient's coverage sits outside standard prompt-pay protection before the visit happens, not after the denial.

Prior authorization support

Authorizations get started and tracked across CareFirst, MCO, and behavioral health portals, with documentation built to the payer's actual medical policy ahead of submission.

Denial management

Denials get sorted by payer and root cause, with appeals built on Novitas LCD policy and Maryland's retroactive-denial protections. Where a carrier won't budge, we can escalate through the Maryland Insurance Administration's complaint process.

Payment posting

ERA and manual posting run against your actual contracted rate, which catches prompt-pay interest a carrier owes but hasn't paid.

AR follow-up

Aging gets worked by how each payer actually behaves, using the same ERISA and federal-plan segmentation described above, instead of one bucket for everything.

Full revenue cycle management

End-to-end service with reporting on clean claim rate, denial rate by payer, days in AR, and net collection rate.

SPECIALTIES

Practices we bill for across Maryland

Different specialties run into different pieces of Maryland's rules. A few examples:

Primary care and MDPCP practices

Care management and performance payments arrive outside the regular claims stream and need their own reconciliation.

Behavioral health and substance use practices

Every claim runs through the state's single ASO, so authorization and payment timing depend entirely on that one vendor's system.

Hospital-based and provider-based groups

Professional and facility charges answer to two different sets of rules under the same visit.

Multi-state and DC-adjacent practices

Patients carry coverage from several neighboring jurisdictions, and a second office across the Potomac can mean a second Medicare contractor.

Ambulatory surgery centers and imaging

Place-of-service and modifier accuracy matter more here as more procedures move out of the hospital under global budgets.

WORKFLOW

Ten stages, front to back

Most Maryland denials trace back to something that happened, or didn't happen, before the claim was ever coded. Getting registration, eligibility, and authorization right catches far more revenue than any appeal recovers later. The stages below cover both ends: what stops a bad claim from going out, and what catches an underpayment once it comes back.

STAGE 01

Registration

Demographic and coverage details captured at intake, including which payer type applies before anything moves further.

STAGE 02

Eligibility

Checked at the specific plan level, down to which of the nine HealthChoice MCOs, or which behavioral health vendor, actually has the patient today.

STAGE 03

Prior authorization

Started and tracked to approval across CareFirst, MCO, or behavioral health portals before the visit happens.

STAGE 04

Coding review

Checked against current CPT, ICD-10-CM, and HCPCS Level II, along with Novitas coverage determinations and payer-specific policy.

STAGE 05

Charge entry

Entered and split correctly between facility and professional charges wherever both apply to the same encounter.

STAGE 06

Claim submission

Filed against each payer's own filing window and tracked through to clearinghouse acceptance, not just submission.

STAGE 07

Payment posting

ERA and manual posting run against your actual contracted rate, with variance and unpaid prompt-pay interest flagged as they post.

STAGE 08

Denial triage

Sorted by payer and root cause first, since the same denial code can mean different things depending on who sent it.

STAGE 09

Appeals

Filed inside both the payer's process and Maryland's statutory windows, built on the specific rule or statute a carrier didn't follow.

STAGE 10

Reporting

Monthly performance measured against clean claim rate, denial rate by payer, days in AR, and net collection rate.

WHY OUTSOURCE

Why practices bring this work to us instead

Maryland's billing environment changes shape depending on which payer, which service line, and sometimes which side of a state line a patient is coming from. Keeping that current inside a practice means one or two staff members carrying knowledge that walks out the door when they leave. Working with a team that handles Maryland claims every day means credentialing clocks, recoupment windows, and MCO-specific eligibility checks get tracked whether or not anyone in your office remembers the statute number.

It also means denials get appealed against the actual rule a carrier violated, not just resubmitted and hoped for. For practices splitting time between patient care and chasing a claim sitting in the wrong queue, that difference shows up directly in days in AR and in what actually gets collected.

COMMON QUESTIONS

Questions Maryland practices ask us

Does Maryland's hospital rate system affect my practice if I'm not hospital-based?

Only indirectly, in most cases. Rate regulation applies to hospital facility charges. Independent physician offices bill under normal CPT and HCPCS logic against the payer's fee schedule, though hospital-employed and provider-based practices need to keep the two separated carefully.

How do I know which HealthChoice MCO to bill?

Eligibility has to be checked at the plan level, not just at the Medicaid level, since members move between the nine MCOs. We verify this before each visit rather than relying on the last file we have.

What happens if a carrier tries to recoup a payment from over a year ago?

Outside of fraud or miscoding, Maryland limits standard recoupments to six months, extended to 18 months for coordination-of-benefits cases. A recoupment request outside those windows can usually be challenged.

Are audio-only telehealth visits still covered?

Yes. Maryland made payment parity and coverage for qualifying audio-only visits permanent for Medicaid and commercial carriers. Medicaid audio-only encounters need the UB modifier, and facility charges usually aren't billable separately for those visits.

Where does Medicare fall for a Maryland practice?

Maryland sits in Jurisdiction L, administered by Novitas Solutions, alongside Delaware, New Jersey, Pennsylvania, and DC. That's a different contractor, with different local coverage determinations, than most of neighboring Virginia.
