Medical billing services in Oregon

Short answer

Medical billing services in Oregon are coordinated care billing: 98 percent of Oregon Health Plan members were in full-benefit managed care in 2024, across 15 coordinated care organizations whose county lines pick the payer. A fee-for-service claim to the Oregon Health Authority has 365 days from the date of service, while CCO contracts ask for initial billings within four months.

Commercial clean claims must be paid or denied within 30 days under ORS 743B.450, and since January 1, 2024 home health agencies have run their own EVV systems and reported every visit to OHA monthly. A Remitwright dedicated biller keeps those rules per payer, serving Oregon practices remotely. Rules for other states are on the medical billing services by state page.

Oregon Health Plan (OHP)

Oregon Health Plan (OHP) is run by the Oregon Health Authority (OHA). Fee-for-service claims and provider enrollment go through the MMIS Provider Portal1, at www.or-medicaid.gov. Almost all coordinated care: CMS counted 1,312,713 of Oregon's 1,340,084 Medicaid enrollees, 98.0 percent, in full-benefit managed care as of July 1, 20243. Members who are not in a coordinated care organization are "open card" fee-for-service members whose claims go to OHA through the MMIS Provider Portal.

Fee-for-service filing limit: 365 days from the date of service for a fee-for-service claim, with a further 180 days to resolve a claim that was submitted inside the 365 days but is still unresolved6. The rule is OAR 410-120-1300. The Provider Portal does not accept a claim past the limit, so a late-resolution claim goes on paper with documentation to OHA's Provider Services Unit in Salem. Managed care plans set their own limits in their provider manuals, so the deadline on an Oregon Medicaid claim depends on which plan holds the member on the date of service.

Each plan is credentialed separately, has its own portal and its own appeal route. A practice that joins Oregon Medicaid through one plan is not in network with the others until each contract is in place.

Commercial payers and the prompt-pay law

Commercial payers active in Oregon12: BridgeSpan Health Company, HealthNet, Kaiser, Moda, PacificSource, Regence, UnitedHealthcare. An Oregon practice works to a separate provider manual for each, with its own filing window, corrected-claim process and appeal levels. Verified payer deadlines, each with its source, are in the timely filing limits table.

Clean-claim payment window under ORS 743B.450, prompt payment of claims: 30 days after the insurer receives a clean claim to pay or deny it, with notice to the claimant by the 30th day when more time is needed10. The delay notice comes from OAR 836-080-0235(4). The Division of Financial Regulation reads insurers' annual prompt payment reports and has issued consent orders with civil penalties over clean claims paid after day 30 without a delay notice, which is the pattern a biller cites when a commercial claim ages past a month. Where the statute earns its place is A/R follow-up: a clean claim that outlasts the window is escalated with the statute cited, and interest is requested where Oregon law provides it.

NEMT and home care in Oregon

Non-emergency medical transportation. Ride services, which OHA also calls brokerages, arrange non-emergency medical transportation for OHP members with OHP Plus benefits, both coordinated care organization members and open card fee-for-service members, and OHP pays travel costs only when the ride service approves them before the appointment or pharmacy visit13. Covered travel runs from taxi, bus and local ride services to gas, meals and lodging, and the member calls the ride service before the day of the visit. The NEMT billing in Oregon page covers trip documentation, broker claims and reconciliation.

Electronic visit verification. Provider Choice Model for home health: Medicaid home health agencies contract with an EVV vendor of their own, built to OHA's specifications, and have had to meet the requirement since January 1, 2024 after OHA moved the start from January 1, 202314. OHA does not supply an EVV system for agencies; it publishes the required data specifications and lets each agency pick its business solution. See home care billing in Oregon for waiver programs, EVV exceptions and authorizations.

Rules that change how Oregon claims are billed

  • CCO contracts ask for the first bill within four months of the service8

    Under OAR 410-141-3565 and the CCO contract, providers submit initial billings to the coordinated care organization within four months of the date of service, stretching to 12 months only for retroactive deletions or enrollments, pregnancy, Medicare as primary payer, third-party resource cases and other delays outside the provider's control. OHA's 2020 guidance clarified that the four months cover the initial claim only, that resubmission of a denied claim for correction falls outside that window, and that CCOs should consider reprocessing claims denied because a correction arrived after four months. Each CCO publishes its own correction window in its provider manual, so two neighboring CCOs can run different clocks for the same practice.

  • Home health agencies report every visit to OHA within ten days of month end15

    Since January 1, 2024 an Oregon Medicaid home health agency has to send OHA a completed EVV Reporting Template no later than ten days after the end of each month, covering all completed visits. Each row carries the claim status, how the visit was captured (automated EVV or manual entry), the member's Oregon Health ID, the rendering provider ID, the name of the person who actually gave the care, the date, start and end times, the start and end GPS coordinates or addresses, up to three revenue codes and the ICN for an adjusted claim. A manually captured visit needs a reason code such as the worker forgetting to clock in, a device error, no internet connection or telephony being unavailable.

  • Homecare workers log time in OR PTC DCI, not on paper vouchers16

    The Oregon Provider Time Capture project replaced paper vouchers for homecare workers and personal care attendants with OR PTC DCI, the Direct Care Innovations system, after a pilot that began August 1, 2021 and a statewide start on September 12, 2021. Authorizations are still created in the state mainframe and then carried into OR PTC DCI, workers enter time and mileage there, and the system was built to meet the federal EVV requirement, so an agency that also employs homecare workers under Aging and People with Disabilities authorizations runs two EVV tracks.

  • The check-cut date is what the regulator counts9

    Oregon's insurance regulator told health insurers in 2005 how it measures the 30-day clean claim rule: the check-cut date is prima facie evidence of payment, compliance is the number of days between the date the claim was received and the date the check was cut, mailroom procedures are examined to confirm payments go out within 30 days, and a 30th day that falls on a weekend or holiday means the check is expected the next business day. The statute was then numbered ORS 743.866 and is now ORS 743B.450, so an unpaid clean claim is escalated with receipt date and check date side by side.

  • OHP has run under a demonstration waiver since 1994 and pre-assigns members4

    CMS's 2024 state tables describe the Oregon Health Plan as a statewide program combining a full-benefit managed care organization with managed long-term services and supports, operating since February 1, 1994 under section 1115(a) demonstration authority together with 1932(a), 1915(b), 1915(c), 1915(i), 1915(j) and 1915(k), with the current waiver running to September 30, 2027. Medicaid enrollees are pre-assigned to a plan. Enrollment is mandatory for low-income adults, limited-benefit members and children with special health care needs and voluntary for aged, blind or disabled members, non-disabled children, full dual eligibles, Native American members and children in foster care.

  • CMS signed off on Oregon's personal care EVV in 202117

    In a letter dated November 2, 2021, CMS told the Oregon Health Authority that the state met the EVV requirements of section 1903(l) of the Social Security Act for personal care services rendered as of October 1, 2021 under the state plan personal care benefit, 1915(c) waivers, the 1915(i) and 1915(k) state plan options and 1915(j) self-directed care, so no federal matching reductions apply to those services. The letter reserved the right to apply reductions if the system does not match the state's attestation, and it requires an updated survey if Oregon adds a personal care authority.

FAQ

Questions from Oregon practices

What is the Oregon Health Plan timely filing limit?

For a fee-for-service claim to OHA, 365 days from the date of service under OAR 410-120-1300, and a claim that was submitted inside the 365 days but is still unresolved gets another 180 days to be worked out. The Provider Portal will not take a claim past the limit, so those go on paper with documentation to the Provider Services Unit in Salem. OHA's claims page states the same rule as 12 months to file and 18 months from the date of service to resubmit. CCO contracts ask for the first bill within four months of the service, with 12 months allowed for retroactive enrollment, pregnancy, Medicare-primary and third-party cases.

Which coordinated care organizations do we contract with in Oregon?

Fifteen CCOs, each tied to counties: Advanced Health, AllCare CCO, Cascade Health Alliance, Columbia Pacific CCO, Eastern Oregon CCO, Health Share of Oregon, InterCommunity Health Network CCO, Jackson Care Connect, three PacificSource Community Solutions plans for Central Oregon, the Columbia Gorge and Marion and Polk counties, Trillium Community Health Plan's Southwest and Tri-County plans, Umpqua Health Alliance and Yamhill Community Care. In CMS's 2024 count Health Share of Oregon alone had 433,927 members. A practice drawing patients from two counties can face two CCOs with two credentialing files and two correction windows.

How quickly must insurers in Oregon pay a clean claim?

ORS 743B.450(1) gives an insurer 30 days from the date it receives a claim under a health benefit plan to pay a clean claim or deny it, and OAR 836-080-0235(4) requires a notice to the claimant by the 30th day if it needs more time. The Division of Financial Regulation measures the window from the receipt date to the check-cut date, with a weekend or holiday 30th day pushing payment to the next business day, and insurers report every claim closed later than 30 days by March 1 each year. Consent orders with civil penalties have followed for clean claims paid late without a delay notice.

Does Oregon require EVV for home health and in-home care visits?

Yes, in two forms. Medicaid home health agencies have had to use an EVV system of their own choosing since January 1, 2024, because OHA chose the Provider Choice Model, publishes the data specifications and does not provide a system, and they send OHA a completed EVV Reporting Template of every visit within ten days after each month ends. Homecare workers and personal care attendants paid through Aging and People with Disabilities record time in OR PTC DCI, the state's Provider Time Capture system, which went statewide on September 12, 2021. CMS confirmed in November 2021 that Oregon's personal care EVV met the federal requirement.

Who arranges NEMT rides for our OHP patients?

A ride service, which OHA also calls a brokerage. Each coordinated care organization has a ride service for its members and open card fee-for-service members have one too, listed by county on OHA's ride service map. Rides are a benefit for members with OHP Plus coverage, they cover taxi, bus and local ride services as well as gas, meals and lodging, and OHP pays only when the ride service approved the trip before the appointment. A transportation provider reconciles trips against the brokerage that authorized them.

Where do OHP fee-for-service claims go, and what does the portal do?

To OHA through the MMIS Provider Portal at or-medicaid.gov, which is open around the clock for individual claims, prior authorization and plan of care requests, and for real-time checks on member eligibility, CCO enrollment, fee-for-service claim status and prior authorization status. A new provider gets a PIN letter within five or six business days of enrolling with OHA and needs it to set up access, and the portal runs only in Mozilla Firefox or Microsoft Edge. Claims for CCO members go to the CCO, so the eligibility check that shows CCO enrollment is the first step on every date of service.
