Portland Medical Billing & Credentialing
We’re a Portland medical billing and credentialing team for Oregon behavioral health and outpatient practices. We fix billing problems, add providers, prepare the Oregon Practitioner Credentialing Application (OPCA) for each payer and help practices open. Credentialing is $450 to $700 per payer, per provider, and Ongoing Billing is 7% of collections for a solo provider with a $300 monthly minimum, down to 4.5% at 26 to 50 providers.
Choose The Help Your Oregon Practice Needs
There are two ways in. You’re opening a practice in Oregon, or you’ve got billing problems or growth to sort out in a practice that’s already running. Pick the one that fits.
Opening A Practice In Oregon
You don’t need your business, Tax ID or NPI before you start. We walk you through them, then coordinate the included payer enrollment, billing setup, EHR, scheduling and staff preparation. We confirm each payer’s status before your staff start booking that payer’s patients.
See First Practice Launch →Medical Billing Problems Or Practice Growth
Maybe claims are going unpaid, A/R is aging, a new provider needs enrolling, or the way your team works stopped fitting a while ago. We agree on the exact work, who’s responsible for what and the handoff before we start.
Discuss the work →What An Oregon Practice Needs Before Payer Enrollment
Oregon uses a standard provider credentialing application, while each health plan, hospital, insurer, or other organization still sets its own requirements. These are the core items we confirm before submission.
Active, Unrestricted Oregon License
OSBN, OBPE, or Oregon Medical Board, current, with no pending board actions. We pull verifications and flag inconsistencies before submission. For psych NPs, our Oregon PMHNP requirements guide covers scope and prescribing.
Professional Liability Coverage
We confirm the current coverage documents, the practice’s legal name, coverage limits, and any tail-coverage information required by each payer before submission.
NPI Type 1 And Type 2
An individual NPI for each provider plus a group NPI tied to the practice EIN. We verify NPPES, taxonomy codes, and group-vs-individual configuration before enrollment.
DataSpring Provider Profile (Formerly CAQH)
Current, fully populated, and supported by the required documents. Outdated or incomplete CAQH data is a common source of preventable follow-up.
Business Documents
EIN letter (CP 575), W-9, payer-accepted bank account documentation for EFT enrollment, Articles of Incorporation or LLC formation docs, and Oregon Secretary of State registration.
OPCA: Oregon Practitioner Credentialing Application
Oregon’s standard credentialing application. Each health plan, hospital, insurer, or other organization still sets its own requirements, so we align the shared information to each submission.
Why Oregon Experience Matters
We’re based in Portland and work Pacific time, same as you. That matters when credentialing, billing, the EHR and an opening date all have to line up. We write down each payer’s current requirements and keep the owner or administrator up to date on what’s moving, what’s waiting and what needs their attention.
Our founder learned professional billing at OHSU, here in Portland. We serve psychiatry, PMHNP, therapy and physician practices across the state, from Eugene and Corvallis to Medford and the coast.
Aetna · Regence BlueCross BlueShield of Oregon · Evernorth Behavioral Health (Cigna) · Moda Health · Providence Health Plan · PacificSource · Optum Behavioral Health (UnitedHealthcare) · Samaritan Health Plans
Each of those plans runs its own credentialing and claim rules. Our guide to billing Oregon’s behavioral health payers shows where they differ.
Four Portland Payer Facts That Change Your Plan
Each of these changes which applications a Portland practice files first, so we check them at the source before we build your payer list.
Portland Medicaid Is Two CCOs, Not One
Health Share of Oregon and Trillium Community Health Plan’s Tri-County region both serve Multnomah, Washington and Clackamas counties. Covering Portland’s OHP patients usually means contracting with both. Our guide to Oregon credentialing and OHP enrollment walks through the order.
Providence Behavioral Health Is Closed In The Tri-County Area
Providence lists its behavioral health network as open in every Oregon county except Multnomah, Washington and Clackamas. Moda lists psychiatrists, psychologists and mental health nurse practitioners as open in every Oregon county, Portland included. See which Oregon panels are open, by credential and county.
Clark County Is Regence Territory, Not Premera
Premera Blue Cross serves Washington except Clark County, and Regence BlueCross BlueShield of Oregon sells Blue plans there. For Vancouver-side patients, the Blue contract that matters is Regence, not Premera. Our Washington payer enrollment guide covers the rest of the state.
PEBB Drops Providence Health Plan In 2027
PEBB, the Public Employees’ Benefit Board, won’t offer Providence Health Plan medical plans in 2027. Moda PPO replaces the Providence Statewide PPO, Moda Coordinated Care replaces Providence Choice and Moda Synergy, and Kaiser’s two plans continue. If state employees fill part of your schedule, check your Moda contract before January. Salem practices feel it most.
These facts and the credentialing clock below come from the Oregon Health Authority’s CCO service areas, Providence Health Plan’s behavioral health network page, Moda Health’s Oregon open panels, Premera’s service area statement, the Washington insurance commissioner’s 2026 individual plans by county, PEBB’s 2027 Summary of Changes and ORS 743B.454. We checked each one on October 4, 2026.
Questions Oregon Practice Owners Ask
How Long Does Oregon Commercial Credentialing Take?
Most Oregon commercial payers take 60 to 120 days from a complete application. ORS 743B.454 gives a health insurer 90 days to approve or reject a complete credentialing application, and contracting and system setup can run past that decision. The clock starts only once the file is complete, so we clear the usual holdups first, like an unattested CAQH profile, W-9 and NPPES data that don’t match, or a missing document.
What Professional Liability Insurance Do Oregon Payers Require?
Coverage requirements vary. We confirm the declarations page, coverage limits, the practice’s legal name, and any tail-coverage documentation each payer currently requires before submission.
Do We Have To Fill Out The OPCA Separately For Every Payer?
The OPCA is Oregon’s standard application, but each payer still sets its own packet and process. We prepare the shared information once, then align each submission to the payer’s current requirements.
Can You Handle Credentialing Alongside Billing And EHR Cleanup?
Yes. They depend on each other. Credentialing sets the effective date, billing can’t send that provider’s claims before it, and the EHR needs the payer and provider set up correctly before either one works. We coordinate all three and show you what’s moving, what’s waiting and what needs your attention.
How Do You Handle A Messy License History Or A Gap In Dates?
We document the history clearly, gather the supporting records each payer requests, and flag gaps before submission. Payers decide participation and may request additional review.
What If I Am Switching EHRs Mid-Credentialing?
Before the switch, we map your payer enrollments, the clearinghouse setup and every open A/R balance. Then each step of the move gets an owner. One of them is the ERA enrollment. If it still points at the old clearinghouse, that’s where your remittances keep landing. Payer and software company decisions stay outside our control.
Do You Work With Physicians And Specialty Practices In Oregon?
Yes. We handle credentialing and contracting, medical billing and operations for physicians and outpatient practices across Oregon, as well as psychiatry, PMHNP and therapy practices. See physician credentialing.
