Medical Billing Services in Seattle, Washington

Seattle’s practice market runs at two speeds. A large share of the city’s clinicians work inside big employed groups, where billing is handled by a central office the individual practice never sees. Alongside them sits a deep bench of independent practices — psychiatry and therapy clinics, specialty groups, primary care practices across King County — that carry their own billing, their own payer contracts, and their own receivables. For those practices, billing is not a back-office detail. It is the work that decides whether a full schedule turns into collected revenue.

Fastora Medical Billing Solutions handles that work for Seattle practices: claims, denials, eligibility, credentialing, and the steady follow-up in between. This page is about the Seattle market and Washington’s payer structure specifically. For the nationwide picture, see our medical billing services across the United States.

An employed market, and the independents billing alongside it

When so many clinicians in a market are employed, independent practices feel it in specific ways. They compete for the same patients without a system’s billing department behind them, and they absorb every enrollment, contracting, and claim-follow-up task themselves. A two-provider therapy practice has the same payer obligations as a hospital department — the same credentialing files, the same authorization rules, the same filing deadlines — with a fraction of the staff to carry them.

Clinicians also move between the two worlds. A psychiatrist leaves an employed position and opens a solo practice; a group recruits a provider away from a system; an established practice adds a clinician whose payer enrollment history sits somewhere else. Every one of those moves is a billing event: enrollment records, payer contracts, and billing setups have to follow the clinician, and claims sent under the wrong arrangement deny. In a market with this much movement between employed and independent practice, keeping enrollment and contracting current is not annual housekeeping — it is a standing workflow.

Apple Health in Seattle: integrated coverage, more than one claim destination

Washington’s Medicaid program is Apple Health, administered by the state Health Care Authority (HCA). Washington completed a move to integrated managed care: for most Apple Health members, physical health and behavioral health — mental health and substance use disorder treatment — are covered together through a managed care plan rather than split between separate systems. In practical terms, the same plan that pays a member’s medical claims also pays their behavioral health claims, and the claim goes to the plan, not to the state.

The edge cases are where Seattle practices lose money. Some Apple Health services and populations remain fee-for-service, billed to HCA directly. And a patient whose physical health coverage sits outside an integrated plan can have their behavioral health covered through a Behavioral Health Services Only arrangement attached to a managed care plan — which means a therapy or psychiatry claim for that patient belongs somewhere different from their medical claims. Eligibility checks therefore have to answer more than “is coverage active.” They have to establish which arrangement covers which service, for this patient, this month.

Underneath all of it sits ProviderOne, HCA’s enrollment and claims system. Groups enroll as billing providers, and the clinicians practicing under them enroll as servicing providers linked to that billing provider — a claim from a clinician whose linkage is missing or stale is a denial built into the setup. Enrollment status, revalidation, and plan assignment all live in the same system, and keeping them current is part of the billing work, not a separate project.

What Fastora handles for Seattle practices

Seattle practices use Fastora for the complete billing cycle, or for the specific pieces their own team has the least capacity for:

• Claims submission and follow-up. Claims are prepared, checked, and sent to the right payer or plan — commercial, Medicare, or the member’s Apple Health plan — then tracked until each one is resolved.
• Denial management and appeals. Denials are worked by reason — corrected, resubmitted, or appealed where the documentation supports it — instead of aging in a queue.
• Eligibility verification. Coverage is confirmed before the visit, including which Apple Health arrangement covers the service: an integrated managed care plan, a Behavioral Health Services Only arrangement, or fee-for-service.
• Prior authorization. Approvals are requested and tracked, including across recurring behavioral health care where authorizations have to stay current session after session.
• Credentialing and enrollment. Providers are enrolled and kept current with payers and with Apple Health in ProviderOne, including the servicing-provider linkage group claims depend on.
• Accounts receivable recovery. Aged claims are reviewed and worked in order of recoverability, and the causes behind them are fixed so the backlog does not rebuild.
• Payment posting and reconciliation. Payments and remittances are posted and reconciled, which is also how underpayments surface when a plan pays below the contracted rate.

Fastora brings 5+ years of medical billing experience, a roster of 50+ active clients, and work with 100+ satisfied MDs. You pay a percentage of collections or a flat monthly fee; during the initial audit, we will set both side by side with your current billing costs.

Specialty billing in the Seattle market

Behavioral health. Behavioral health is the lead specialty in the Seattle market — group practices, community clinics, solo therapists — and integrated managed care changed its billing in ways practices still trip over. The behavioral claim follows the member’s plan, authorizations have to stay current across recurring care, and the fee-for-service and Behavioral Health Services Only exceptions decide a meaningful share of claims before they are ever coded. That combination is the focus of our behavioral health billing support.

Psychiatry. Psychiatry practices in Seattle run small and busy, often with a heavy telehealth share. The billing turns on detail: evaluation and medication-management coding that matches the documentation, therapy add-on codes used correctly, and plan rules applied visit by visit. Small errors repeat on every claim until they are found. See how we handle psychiatry billing services for practices like these.

ABA therapy and rehabilitation. ABA practices bill in units against authorizations and treatment plans that must stay current, while physical and occupational therapy billing runs on units, modifiers, and visit limits tracked across plans of care. Both are precision work at volume — the kind of billing that rewards a systematic process and punishes an occasional one.

Frequently asked questions

We are hiring a clinician away from a large system. What does billing need before they start?

Their payer enrollment has to exist under your practice, not just their old employer: contracts and enrollment records in your group’s name, Apple Health enrollment in ProviderOne with the servicing-provider linkage to your billing provider, and authorization workflows pointed at your practice. Until that groundwork is in place, claims for their work will deny or pay the wrong entity, so it belongs on the hiring checklist, not after the first schedule fills.

How do Apple Health claims work for a Seattle practice?

For most members, claims go to the member’s Apple Health managed care plan, which covers physical and behavioral health together. Two exceptions matter: some services and populations remain fee-for-service and bill to the Health Care Authority directly, and a patient outside an integrated plan may have behavioral health covered through a Behavioral Health Services Only arrangement. The eligibility check has to identify which of these applies before the claim is built.

Can you handle behavioral health and psychiatry billing?

Yes — both are core parts of our work, and in this market they are the most detail-sensitive: integrated-plan routing, the Behavioral Health Services Only exception, authorizations kept current across recurring care, and telehealth visits coded with the right place of service and modifiers for each plan. We set those workflows up with you at the start rather than learning them from your denials.

A lot of our care is delivered by telehealth. Does that change the billing?

It changes the details rather than the structure. Each payer sets its own telehealth rules — which services are covered, which place-of-service codes and modifiers it expects — and those rules have to be applied claim by claim. A telehealth visit billed the way the plan expects for an in-person visit is a common and avoidable denial in therapy and psychiatry practices.

Do you only work with practices in Seattle itself?

No. We work across King County — Bellevue, Redmond, Kirkland, Renton, and the rest of the metro — and with practices throughout Washington. The work is handled remotely either way; what matters is your specialty mix, your payers, and which parts of billing you want handled.

What does Fastora charge?

Either a percentage of collections or a flat monthly fee, depending on the size of your practice and the scope of the work. At the initial audit we will price both against your current billing costs, so you are comparing actual figures rather than an estimate.
