Fast answers start with OPIS

When you need patient or claim information, our web Online Provider Information System (OPIS) helps you get there without the extra runaround. It’s our secure, HIPAA-compliant provider portal built to give your team 24/7 access to the details that keep care, billing, and follow-up moving.

OPIS is available at no cost to providers. Once registered, your account shows information tied to your submitted Tax ID, so your team can quickly find the member, plan, and claim details relevant to your practice.

Verify patient eligibility

Confirm whether a member’s coverage is active and view the most current effective date on file. You can search using the main subscriber’s Healthcare ID number or Social Security number.

Review member details

Access family summary and individual member detail screens to understand who is covered, which plan applies, and what information is connected to the submitted Tax ID.

Check claim status

View claim summary and claim detail information, including where a claim stands and the details available for follow-up or payment review.

Review patient correspondence

Find patient-related communications in one place, making it easier to track plan communications and respond when additional follow-up is needed.

View electronic remittance advice

Access electronic remittance information to support reconciliation, payment posting, and cleaner billing workflows.

Review plan text and plan history

Look up plan language, benefit details, limitations, requirements, and plan history so your team can better understand how coverage applies.
