The MDX Hawaii prior authorization form is submitted through the CapConnect provider portal at capcms.com, and it should be filed at least seven days before the planned date of service.1UnitedHealthcare Provider. 2026 Medicare Advantage Quick Reference Guide: MDX Hawaii A clean submission needs the member’s ID, the requesting provider’s NPI and Tax ID, ICD-10 and CPT or HCPCS codes, and clinical documentation that supports medical necessity. Get those pieces right the first time and approval is usually straightforward; miss one and the request bounces back or stalls in review.
Check Whether You Actually Need Authorization
Not every service triggers prior authorization. Inpatient and outpatient services generally do not require it when a member is referred to a healthcare professional already contracted with MDX Hawaii’s network.1UnitedHealthcare Provider. 2026 Medicare Advantage Quick Reference Guide: MDX Hawaii The requirement applies mainly to out-of-network referrals, high-cost procedures, certain specialty drugs, and any service that appears on MDX Hawaii’s authorization lists.
Two separate lists exist: one for medical procedures and one for prescription drugs. Both live on the CapConnect portal at capcms.com and on UHCprovider.com/priorauth under Advance Notification and Plan Requirement Resources.1UnitedHealthcare Provider. 2026 Medicare Advantage Quick Reference Guide: MDX Hawaii Check them first. If the service is not listed and the referral is in-network, you likely do not need to file at all.
What to Gather Before You Start
Incomplete submissions are the main reason requests get delayed. Have everything in hand before you open the form.
Patient Identifiers
You need the patient’s full legal name, date of birth, and MDX Hawaii member ID number. The member ID links the request to the correct insurance profile, and a single transposed digit can route it to the wrong person or trigger an automatic rejection. For UnitedHealthcare Medicare Advantage members administered by MDX Hawaii, the ID appears on the insurance card.
Provider Credentials
The requesting provider must supply a ten-digit National Provider Identifier and federal Tax Identification Number. Both numbers let MDX Hawaii confirm that the provider is active in the network and eligible for reimbursement. If either is wrong or missing, medical management has to verify the source manually, which adds days.
Diagnosis and Procedure Codes
Every request needs ICD-10 diagnosis codes describing the patient’s condition and CPT or HCPCS codes defining the treatment. The system cannot process the request or calculate the fee schedule without them. Confirm that the diagnosis codes logically support the procedure; a mismatch is a common denial trigger.
Clinical Documentation
Attach recent clinical notes, lab results, imaging reports, or other records that show why this specific treatment is medically necessary for this specific patient. Reviewers compare the documentation against clinical guidelines, so specificity matters. Thin documentation is what pushes a request into additional review or an outright denial.
Getting to the Current Form
The form is not a standalone download on MDX Hawaii’s main website. Go to mdxhawaii.com/forms-and-resources, which directs you to capcms.com.2MDX Hawaii. Forms and Resources You can register for a portal account directly at capcms.com if you don’t already have one. For help with account setup, call Conifer Customer Service at 1-808-522-7500.3MDX Hawaii. Provider Portal Page Link
Once inside the portal, use the current version of the form. Older saved copies may be missing fields the current system requires.
Filling Out the Form
The form’s sections track the information you gathered. Patient demographics go in the header. Below that, enter the servicing provider’s name, location, NPI, and contact information, then the requested dates of service. Those dates matter after approval: if the actual service date falls outside the authorized window, claims processing can reject the billing even with a valid authorization number.
One field asks whether the request is routine or urgent. Mark it urgent only when a delay could seriously jeopardize the patient’s life or health. Urgent status triggers a faster review track, but MDX Hawaii scrutinizes it closely, and if the clinical record does not support genuine urgency the request gets reclassified as routine and slotted into the standard timeline. Elective or non-emergent services are routine.
File the request at least seven days before the planned date of service.1UnitedHealthcare Provider. 2026 Medicare Advantage Quick Reference Guide: MDX Hawaii That lead time gives you room for any back-and-forth if MDX Hawaii asks for more documentation.
Submitting the Form
Submit through the CapConnect portal at capcms.com when possible. You get immediate confirmation of receipt, you can upload supporting documents directly with the form, and you can track pending requests without calling in.3MDX Hawaii. Provider Portal Page Link

After Submission
Reviewers compare your documentation against MDX Hawaii’s medical policies and national clinical guidelines. Routine requests move on the standard timeline; urgent requests are expedited when the record supports it. Both the requesting provider and the member receive the decision by mail or electronic communication.
An approval comes with an authorization reference number. Put that number on the final billing claim. Without it, the claim can be denied even though the service was authorized. File the approval notice with the original request in the patient’s record.
If the Request Is Denied
The denial notice explains why the request did not meet approval criteria and how to appeal. Read the reason first. Many denials come from fixable documentation gaps rather than a real disagreement about medical necessity, and adding evidence and resubmitting can be faster than a formal appeal.
Internal Appeal
The first step is an internal appeal through MDX Hawaii’s own review process. Hawaii law requires managed care plans to maintain a complaints and appeals procedure for enrollees, and the plan must include the details in the denial notice. For urgent clinical situations, Hawaii law provides an expedited internal appeal on a faster timeline.
External Review
If the internal appeal does not reverse the denial, the enrollee or their representative can request external review from the Hawaii Insurance Commissioner within 130 days of the notice of adverse action. An independent review organization randomly assigned by the Commissioner conducts the review, not MDX Hawaii or the health plan. The health carrier has five business days to submit all documents it relied on, and the independent reviewer issues a decision within 45 days.5FindLaw. Hawaii Code 432E-34 – External Review There is no fee to the enrollee for external review.
