Billing in Hawaii: what's different

The rules below change how a claim is filed and paid in Hawaii. Each line links to the official page it was read from, and the date at the top of this page is when it was last checked.

Rules that change how Hawaii claims are billed

• HOKU registration comes before any plan contract, and it reaches ordering, referring and prescribing clinicians¹

  UnitedHealthcare's 2026 Hawaii manual states that the Med-QUEST Division requires every provider who serves QUEST members to be enrolled with the Department of Human Services as a Medicaid provider through HOKU, the Division's web-based enrollment system at medquest.hawaii.gov/HOKU, and that this applies to ordering, referring and prescribing providers such as physicians, APRNs, dentists, optometrists and audiologists even when they never bill Medicaid themselves. Out-of-state ROPA providers are exempt only under narrow conditions such as Medicare enrollment and limited service duration, new providers must register before contracting and existing ones before renewal, and the HOKU hotline answers at 1-808-692-8099 or 1-833-909-3630. A clinician who only refers or prescribes still needs a HOKU registration before the plans will contract or renew.

• One filing window for every plan, borrowed from the state manual²

  Ohana Health Plan's provider manual, effective March 23, 2026, requires initial, corrected and voided claims within 12 months of the date of service, keeps the same 12 months for members whose eligibility was granted retroactively, and gives six months from the primary payer's explanation of payment or 12 months from the date of service, whichever is greater, when Medicare or another third party pays first, citing the Hawaii Med-QUEST Provider Manual, Claims Payment, Section 4.3.5 as the origin of each rule. The manual lists the documents it accepts as proof of timely submission and warns that a claim arriving after the window, or failing the plan's clean claim requirements, may be denied, so the proof-of-submission file matters as much as the submission.

• Fifteen days electronic, thirty days paper²

  The same Ohana manual commits the plan to reimburse a clean claim that it has not contested or denied within 30 calendar days of receiving it in writing and within 15 calendar days of receiving it electronically, unless the provider agreement sets a shorter window. The manual also requires claims to arrive as HIPAA-compliant 837 transactions or on the CMS-1500 and UB-04, routes claim payment disputes to the plan's Tampa post office box and separates disputes about timely filing and medical records from appeals over prior authorization. For a practice the difference between 15 and 30 days is a reason to retire paper claims entirely.

• Everyone is in a plan, and the plan can change on the first of any month⁵

  CMS's 2024 state tables record Med-QUEST as a statewide program under 1115(a), 1937 and 1902(a)(70) authority with its current period starting August 1, 2019, enrolling every population from low-income adults to full dual-eligible members and children in foster care on a mandatory basis. An applicant may choose a plan at application; otherwise the state auto-assigns one and the member has 60 days to switch, with the change effective the first day of the next month, and every member may move plans once a year with the change taking effect at the start of the benefit year. The tables also list personal care, HCBS waiver services, nursing facility care and non-emergency transportation as plan benefits, with HSAG as the external quality reviewer.

• The 2025 extension runs to December 31, 2029 and adds services with their own billing rules⁴

  CMS approved Hawaii's request to extend the QUEST Integration demonstration on January 8, 2025, effective through December 31, 2029, continuing most of the authorities from the 2019 extension and the continuous eligibility amendment. The approval adds health-related social needs services with non-medical transportation to reach them, a contingency management benefit for stimulant and opioid use disorder that the Department of Human Services delivers, assisted living facility services for the at-risk population and limited coverage for certain incarcerated individuals in the 90 days before release. The special terms and conditions keep the HCBS requirements, including the electronic visit verification system, as conditions of the demonstration.

• Three mutual benefit societies and a handful of HMOs make up the commercial market⁹

  The Insurance Commissioner's 2025 annual report lists the mutual benefit societies and health maintenance organizations authorized in Hawaii during 2024: Hawaii Medical Service Association, University Health Alliance and Hawaii Management Alliance Association as mutual benefit societies, and AlohaCare, Kaiser Foundation Health Plan's Hawaii Region, Devoted Health Plan of Hawaii, CHA HMO and Humana Wisconsin Health Organization as HMOs, with HMSA reporting 715,247 members, Kaiser's Hawaii Region 266,921, AlohaCare 71,919, UHA 58,935 and HMAA 36,963. HMSA and Kaiser also hold two of the five QUEST contracts, so the same company often pays a Hawaii practice under a commercial agreement and a Medicaid agreement with different rules.
