We run your dual-eligible billing
This is the operator-layer billing service for practices that serve dual-eligible patients, the millions of dual-eligible Americans covered by both Medicare and Medicaid. The crossover from Medicare to Medicaid is where the money stalls: the Coordination of Benefits Agreement is supposed to auto-transfer each claim to the state Medicaid program, but mismatched demographics, outdated Medicaid IDs, and plan misalignment park the secondary balance in A/R. Staffingly is the outsourced back-office team that runs that work on top of the practice management system you already use: COBA crossover follow-up across state Medicaid systems, QMB balance-billing compliance and patient-balance scrubbing, A/R recovery on stalled dual claims, Medicaid provider-enrollment coordination, and demographic and ID reconciliation. We are the people, not another tool. You keep every coverage and clinical decision; we run the dual-eligible back office on a flat per-specialist fee, never a percentage of your collections.

You cannot balance-bill a QMB patient
Federal law prohibits all Medicare providers, not only those who accept Medicaid, from balance-billing Qualified Medicare Beneficiaries (QMBs) for Medicare Part A and Part B cost-sharing such as deductibles, coinsurance, and copays, under Section 1902(n)(3)(B) of the Social Security Act. CMS identifies improper billing of QMBs as a persistent compliance failure. When the claim is billed correctly, a dual-eligible QMB carries a $0 patient balance. To collect Medicare cost-sharing for duals, a provider generally must be enrolled in that state’s Medicaid program, which is a credentialing prerequisite. The work of getting this right, scrubbing QMB balances so nothing improper reaches the patient and recovering the secondary balance from the state instead, is exactly what our team runs as your back office.
The Coordination of Benefits Agreement (COBA) is supposed to auto-transfer the Medicare claim and its remittance to the state Medicaid program, but the crossover stalls when patient demographics are mismatched, the Medicaid ID is outdated, or the plan record is misaligned. The Medicare side pays, the Medicaid secondary balance ages, and the patient is sometimes billed by mistake for cost-sharing that is federally prohibited. Our team works that gap: reconcile the data, follow the crossover, submit state by state where COBA does not auto-transfer, and keep QMB balances off the patient. This is general information, not legal advice; confirm specifics with your own counsel.
The dual-eligible back office, run by a HIPAA-trained team
COBA crossover follow-up
We follow each Medicare-to-Medicaid crossover across state Medicaid systems, confirm the claim transferred, and work the ones that did not so the secondary balance gets resolved instead of aging quietly in A/R.
QMB balance-billing compliance
We scrub dual-eligible patient balances so federally prohibited QMB cost-sharing is never sent to the patient. When the dual claim is billed correctly, the patient balance is $0, and we keep it that way.
A/R recovery on stalled dual claims
Stalled crossover claims park the Medicaid secondary balance in A/R where nobody works it. We work that aged dual-eligible A/R queue, resolve the data and submission gaps, and recover the secondary balance.
Medicaid provider-enrollment coordination
Collecting Medicare cost-sharing for duals generally requires state Medicaid enrollment. We coordinate the enrollment paperwork so you are positioned to collect the cost-share you are owed.
Demographic & ID reconciliation
Mismatched demographics and outdated Medicaid IDs are the most common reason crossover fails. We reconcile patient data against state records so claims match and transfer the way they should.
State-by-state crossover submission
Where COBA does not auto-transfer, we submit the Medicaid secondary claim directly to the correct state program, following each state’s process so the balance is captured rather than written off.
Reporting
You get clear weekly reporting on crossover status, aged dual-eligible A/R, recovered balances, and enrollment progress, all logged inside your own system under role-based access.
Operator role, not legal advice
We run the billing operation. We never make eligibility, coverage, or legal determinations, and we never give legal advice. Your practice owns every coverage and clinical decision.
D-SNP, C-SNP, and I-SNP, in plain terms
Special Needs Plans are Medicare Advantage plans built for specific populations, and the dual-eligible world runs through them. The SNP rules are mid-transition through the 2025 to 2027 window, so plan details continue to shift, and D-SNPs now exist in nearly every state. Knowing which plan a patient carries changes how the crossover and cost-share work. This is informational, not legal advice.
D-SNP (Dual-Eligible Special Needs Plan) is Medicare Advantage integrated with State Medicaid; it absorbs coordination of benefits and carries a $0 cost-share for approved services, which is why getting the integration right matters so much. C-SNP (Chronic Condition Special Needs Plan) targets people living with specific severe or disabling chronic conditions. I-SNP and IE-SNP (Institutional and Institutional-Equivalent Special Needs Plans) serve members who live in a facility or meet an institutional level of care. Our team is trained on how each plan type changes the crossover and the patient balance, so dual claims are worked correctly the first time.

How Staffingly works, in practice
Inside the workA BAA-signed Staffingly team works inside your existing billing system and the state Medicaid portals, running COBA crossover follow-up, QMB balance scrubbing, A/R recovery, and enrollment coordination, with clear escalation back to your practice.
What this looks like for a practice serving duals
A de-identified composite of how the model runs in practice.
Consider a primary care group with a large dual-eligible panel across two state Medicaid programs. Medicare pays cleanly, but the secondary side is a mess: crossover claims stall on mismatched demographics, aged dual A/R keeps growing, and a few QMB patients were billed for copays they should never have received. Staffingly steps in as the operator layer on top of the billing system. Our team reconciles patient demographics and Medicaid IDs, follows each COBA crossover and submits directly to the state where the auto-transfer failed, works the aged dual A/R queue, scrubs QMB balances so nothing improper reaches a patient, and coordinates the Medicaid enrollment needed to collect cost-share. The group keeps every coverage and clinical decision. We charge a flat weekly fee and report back every week. This is informational, not legal advice.
How does Staffingly use AI in a dual-eligible workflow?
AI handles the repetitive first pass; a specialist owns every claim and judgment call; your practice owns all coverage and clinical decisions. Everything runs inside your own system, logged under role-based access.
AI flags stalled crossover claims
AI watches for crossover claims that did not transfer and for aging dual-eligible secondary balances, so a stalled claim surfaces in minutes instead of months and the specialist can work it right away.
AI surfaces QMB balance risk
AI flags dual-eligible accounts where a patient balance has been created for cost-sharing, so the team can scrub the QMB balance before anything improper is ever sent to the patient.
A specialist owns every claim
A dedicated specialist owns every dual claim and every judgment call. AI prepares and flags; the human reconciles the data, submits to the state, and recovers the secondary balance.
Logged under role-based access
Every crossover action, submission, and balance adjustment is logged with an audit trail under role-based access inside your system. Your practice owns all coverage and clinical decisions; we run the back office.

Frequently asked questions
Can I bill a QMB patient for a Medicare copay?
No. Federal law prohibits all Medicare providers, not only those who accept Medicaid, from balance-billing Qualified Medicare Beneficiaries for Medicare Part A and Part B cost-sharing such as deductibles, coinsurance, and copays, under Section 1902(n)(3)(B) of the Social Security Act. When the claim is billed correctly, a QMB carries a $0 patient balance. Improper billing of QMBs is a persistent compliance failure flagged by CMS. Our team scrubs dual-eligible patient balances so QMB cost-sharing is not sent to the patient. This is informational, not legal advice.
Why do my dual-eligible claims stall in A/R?
The Coordination of Benefits Agreement is supposed to auto-transfer the Medicare claim to the state Medicaid program, but the crossover stalls when patient demographics are mismatched, the Medicaid ID is outdated, or the plan record is misaligned. The Medicare side pays, the Medicaid secondary balance parks in A/R, and nobody works it. Our team follows the crossover across state Medicaid systems, fixes the data that stalls it, and submits state by state where the agreement does not auto-transfer, so the secondary balance gets resolved instead of aging.
What is a COBA and how does crossover work?
A Coordination of Benefits Agreement, or COBA, is the arrangement that is meant to automatically route a Medicare claim and its remittance to the patient’s secondary payer, including the state Medicaid program for dual-eligible patients, so the provider does not have to bill the secondary separately. In practice the auto-transfer fails when demographics, Medicaid IDs, or plan records do not match across systems. When that happens the provider has to submit the secondary claim directly to the state, which is the manual follow-up our team runs.
What is the difference between D-SNP, C-SNP, and I-SNP?
A D-SNP is a Dual-Eligible Special Needs Plan, a Medicare Advantage plan integrated with State Medicaid that absorbs coordination of benefits and carries a $0 cost-share for approved services. A C-SNP is a Chronic Condition Special Needs Plan that targets people with specific severe or disabling chronic conditions. An I-SNP, or IE-SNP, is an Institutional or Institutional-Equivalent Special Needs Plan for members who live in a facility or meet an institutional level of care. The SNP rules are mid-transition through the 2025 to 2027 window, so plan details continue to shift. This is informational, not legal advice.
Do I need to be enrolled in Medicaid to get paid for dual patients?
Yes, for the cost-sharing portion. To collect Medicare Part A and Part B cost-sharing for dual-eligible patients, a provider generally must be enrolled in that state’s Medicaid program, which is a credentialing prerequisite even for providers who do not otherwise see Medicaid patients. Without that enrollment the secondary balance cannot be collected and the dual claim parks in A/R. Our team coordinates the Medicaid provider-enrollment paperwork so you are positioned to collect the cost-share you are owed. This is informational, not legal advice.
