Medical Billing Services in Massachusetts (MA) Built Around MassHealth, Not Guesswork
Your front desk verified insurance. Your biller submitted the claim. It still came back denied.
In Massachusetts, that's rarely bad luck. Usually the claim went to the wrong MassHealth plan, or it missed the state's 90 day filing deadline.
MassHealth doesn't run through one simple list of plans. It splits members across ACOs, MCOs, and a separate primary care plan, each with its own network and rules. Add a strict 90 day filing window and a prompt pay law that skips MassHealth entirely, and a generic billing workflow starts losing money fast.
GenMediTech builds MA medical billing around this exact landscape, so your practice stops losing money to plan mix ups, missed deadlines, and rules most billing companies never learn.

Why MA Medical Billing Works Differently
Massachusetts splits Medicaid into more pieces than most states. Here's what actually causes most of the denials we see.
MassHealth Runs on Four Different Plan Types, Not One
Members can land in an Accountable Care Partnership Plan, a Primary Care ACO, a standard MCO like Tufts Health Together or WellSense, or the fee-for-service PCC Plan. Each type routes claims differently. Bill MassHealth like one payer, and claims bounce.
The Filing Window Is 90 Days, and It's Strict
A first-time MassHealth claim must reach the payer within 90 days of the date of service, or 90 days from the date on another insurer's EOB if that insurer was billed first. Miss it, and you need a formal waiver just to get considered. Final resubmission closes at 12 months, or 18 months if another insurer was billed first.
MA's Prompt Pay Law Doesn't Cover MassHealth at All
State law gives commercial insurers 45 days to act on a claim, with interest owed after that. But this law specifically excludes MassHealth, Medicare, and self-funded plans. Different MassHealth plans set their own turnaround times instead.
Two Balance Billing Rules Apply, and the Stronger One Wins
Massachusetts had its own balance billing law years before the federal No Surprises Act. Both apply today. Whichever one protects the patient more is the one that governs the claim.
Boston's Academic Medical Centers Add Another Layer
Mass General Brigham, Beth Israel Lahey, and other large systems run their own ACOs and referral rules. A workflow built for a typical small state misses these local patterns.
Common Revenue Leaks We Find in MA Practices
Most Massachusetts practices we audit aren't losing revenue because of bad patient care. They're losing it to gaps nobody is watching for:
MassHealth 90-Day Filing Misses
A claim sits for a few weeks before submission, and the 90-day clock runs out before anyone notices. Without an approved waiver, that revenue is gone.
Wrong MassHealth Plan Routing
A patient's plan type changed at the annual 90-day selection window, but the claim still goes to their old ACO or MCO. Each plan type has its own portal, so a misrouted claim gets denied, not redirected.
Assuming Prompt Pay Interest Applies to MassHealth
Billing teams sometimes expect the same 45-day, interest-bearing rule for MassHealth claims that applies to commercial payers. It doesn't. Chasing the wrong deadline wastes time and misses the real one.
Missing the Stronger Balance Billing Protection
State law and federal law both apply to out-of-network claims, but they don't always say the same thing. Checking only one leaves money, or compliance, on the table.
Academic Medical Center Referral Gaps
Practices referring into Boston's large hospital systems lose claims to network and prior authorization rules specific to those systems, especially when the referral crosses ACO lines.

What In-House Billing Actually Costs MA Practices

Frequently Asked Questions
MassHealth splits members across ACOs, MCOs, and a separate primary care plan instead of one simple MCO list. Add a strict 90-day filing window and a prompt pay law that skips MassHealth entirely, and generalist billing workflows fall behind fast.
Yes. Accountable Care Partnership Plans, Primary Care ACOs, standard MCOs like Tufts Health Together and WellSense, and the PCC Plan, each tracked as its own path with its own rules.
90 days from the date of service for a first-time submission, or 90 days from the date on another insurer's EOB if that insurer was billed first. Final resubmission closes at 12 months, or 18 months if another insurer was billed first. Missing the initial 90 days requires a formal waiver request.
No. Massachusetts's 45-day prompt pay law with interest only applies to commercial insurers. MassHealth, Medicare, and self-funded plans are excluded. MassHealth's own plans set their own claims turnaround instead.
Yes. Both apply at the same time. Massachusetts requires HMO/PPO plans to pay a reasonable amount for out-of-network emergency care; the federal law adds more protections on top. Whichever one protects the patient more is the one we apply.
Yes. Solo physicians, small clinics, and multi-specialty groups. Our model scales to your volume, and you get a full certified billing team regardless of size.
Most MA practices are fully onboarded within 5 to 7 business days, with no gap in claims submission during the transition.
