Medicaid Premium Billing: Requirements for State Medicaid Agencies

State Medicaid agencies that charge premiums to expansion populations, CHIP families, or buy-in members face a billing challenge unlike anything in commercial insurance. Premiums are small, often $10 to $25 per month. A portion of the population is underbanked. Delinquency rates routinely reach 40 to 50 percent. And the administrative cost of collecting those premiums can consume the revenue they generate if the billing infrastructure is not purpose-built for the problem.

Read on to learn what state technology teams and program managers need from a Medicaid premium billing system, and where general-purpose platforms fall short.

The economics that define Medicaid premium billing

The core challenge is not billing complexity in the traditional sense. It is economic viability. When premiums average $17 per month, the cost of generating an invoice, processing a payment, managing delinquency, and reporting to CMS must remain a fraction of the amount collected.

Published data from similar state programs illustrates the difficulty:

• Arkansas (2017): Only 20% of beneficiaries paid their premiums
• Iowa (2016-2017): Fewer than 25% paid
• Michigan (2017): 44% paid

States that plan for 80% collection rates from day one are disappointed. A realistic planning assumption is 40 to 50 percent initial delinquency, improving over time as members enroll in recurring payments and the program matures.

The metric that determines program viability is administrative cost as a percentage of collected premiums. If it costs $5 to process a $15 payment, the program cannot sustain itself. The target is under 10% of collected premiums for total billing administration costs, and under 15% as a conservative upper bound.

Payment methods for unbanked populations

A Medicaid premium billing system must support payment channels that commercial billing systems rarely consider. A portion of the Medicaid population may not have a bank account. If the only options are ACH and credit card, those members cannot pay.

Required payment capabilities:

• ACH and electronic bank transfers
• Credit and debit card processing
• Retail cash payment networks allowing members to pay in cash at convenience stores and pharmacies
• Online payment portal with real-time balance and payment history
• Recurring automatic payment enrollment to reduce ongoing delinquency
• Phone-based payment (IVR or agent-assisted)

States that offer only checks and online payments see lower collection rates than those offering retail cash and multiple electronic options. The payment method mix directly affects whether the program is financially viable.

Delinquency management and due process

• Advance written notice at least 30 days before disenrollment
• Multiple escalating notices at configurable intervals (30, 60, 90 days past due)
• Plain language notices accessible to members with limited English proficiency.
• Clear opportunity to pay, with automatic cancellation of disenrollment if payment is received
• Communication of appeal rights

The billing system must automatically generate compliant notices, support custom language for each population type, and communicate disenrollment events to the enrollment system only after all due process requirements are satisfied. This is not a feature that can be bolted onto a general-purpose accounts receivable system. It must be built into the billing logic.

Supporting multiple program types in one platform

Most states with premium programs operate more than one. A state may simultaneously bill:

• Medicaid expansion adults (under a Section 1115 waiver, premiums of $10 to $25 based on income)
• CHIP families (premiums of $15+ per family, tiered by income, no waiver required above 150% FPL)
• Buy-in members (higher premiums of $50 to $200 for eligible individuals purchasing Medicaid coverage)

Each program type has different premium amounts, billing frequencies, grace periods, enforcement mechanisms, and reporting requirements. The billing system must support all of them with configurable rules per population, not custom development per program.

Certifi’s rules-based configuration allows distinct premium structures, delinquency timelines, incentive credits, and enforcement actions for each population without requiring separate systems or custom code.

Handling eligibility changes mid-cycle

Medicaid beneficiaries frequently move between eligibility categories. A member’s income changes, a pregnancy begins, a child ages into or out of CHIP. Each transition may start or stop premium obligations, often retroactively.

The billing system must:

• Process eligibility changes from the enrollment system and adjust billing within the current cycle.
• Calculate pro-rated premiums when status changes mid-month
• Generate credits for overpayments when retroactive changes reduce or eliminate premium obligations.
• Cancel pending delinquency events when a member transitions to non-premium status.
• Maintain a complete audit trail for CMS reporting and dispute resolution.

Certifi’s Perfect Balance™ architecture handles automatic retroactive adjustments, maintaining financial integrity with limited manual reconciliation. Enrollment changes received through the MMIS integration are processed and reflected in billing within the current cycle.

CMS reporting and waiver compliance

States operating premium programs under Section 1115 waivers may need to report collection rates, delinquency rates, disenrollment rates, and administrative cost ratios to CMS at defined intervals. The billing system should generate these metrics from transaction data. Manual compilation from spreadsheets is error-prone and unsustainable.

If the waiver includes incentive provisions (premium credits for completing health risk assessments, maintaining employment, or enrolling in electronic payments), the billing system must track participation, apply credits, and report utilization rates.

Certifi has completed CMS certification for a state Medicaid billing and collections module and supports the full range of compliance, reporting, and incentive-tracking requirements that waiver programs often demand.

What makes a Medicaid billing platform viable

The question is not whether a state should charge premiums. It is whether the billing infrastructure can collect them cost-effectively enough to justify the program. States that conclude “premiums aren’t worth collecting” are often making a statement about their technology, not about the program concept.

A purpose-built Medicaid premium billing platform achieves administrative costs under 10% of collected premiums, even with average premiums under $20 per month. Serving state Medicaid programs since 2018, Certifi was built specifically to make these programs viable.
