Oscar Customer Care Number: How to Reach the Right Team Quickly

Quick answer: where to find your Oscar customer care number

Oscar Health assigns different customer care numbers based on your plan type (Individual & Family, Small Group, or Medicare Advantage), state, and even your specific employer group. That means there isn’t a single universal number that works for everyone—your dedicated phone line is printed on your Oscar ID card and shown in your online account and mobile app. Using the number tied to your plan routes you to the concierge team that can actually see your benefits, claims, and authorizations.

The fastest way to get the right number is to check your digital ID card in the Oscar app or log in at hioscar.com. If you’re an employee enrolled in Oscar through your company or a member of a Cigna + Oscar small-group plan, your group ID card and employer benefits portal will also display a plan-specific support line. For privacy and routing reasons, Oscar will ask you to verify your identity before discussing protected health information.

Fastest lookup options

• Oscar mobile app: Open the app, tap your profile or ID card, and look for “Contact” or “Call your Care Team.” The number shown is specific to your plan and location.
• Member website: Go to https://www.hioscar.com and sign in. From the dashboard or ID card page, select “Contact” or “Help.” Your concierge team’s phone number and hours will be listed.
• Physical ID card: Check the front or back of your Oscar ID card for “Member Services,” “Concierge,” or “Customer Care.” There may also be a separate line for providers and prior authorization.
• Employer or broker portal (for small group plans): Your benefits site typically shows the group-specific Oscar support number alongside your plan documents and SBC.
• Welcome emails and PDF packets: Look at your enrollment confirmation email and the “Welcome to Oscar” PDF—these often include your direct customer care number and business hours.

What to expect when you call

Expect a brief identity verification—usually your full name, date of birth, member ID (from your card), and address. For security, Oscar won’t discuss protected health information with anyone else unless you have added them as an authorized representative on file.

Business hours can vary by plan and region, but member services are generally open on weekdays, with extended hours during open enrollment and the start of plan years. Many plans include a 24/7 nurse line you can reach through the same number or via the app, which is best for clinical questions after hours. If hold times are long, ask for a callback if offered.

Prepare before you dial: save time and get resolution in one call

Having the right details ready helps the concierge team solve issues without multiple follow-ups. The more specific you are about dates of service, provider names, and billed amounts, the faster they can trace claim IDs and network contracts. If you’re calling about a preauthorization, have the procedure codes if possible—your provider’s office can supply them.

If you want a spouse, adult child, or caregiver to speak on your behalf, ask Oscar to add them as an authorized representative. For minors, a parent or legal guardian can typically speak for the child after verification. For elder-care scenarios, power-of-attorney or HIPAA release documentation may be requested.

• Member info: Member ID (from card), full legal name, date of birth, address, phone, and email on file.
• Plan details: Plan year (e.g., 2025), metal tier (Bronze/Silver/Gold/Platinum), deductible and out-of-pocket maximum amounts if known.
• Provider details: Provider’s full name, NPI if available, facility name, and whether it’s in-network (from Oscar’s directory).
• Claims and bills: Claim number(s), date(s) of service, CPT/HCPCS codes if available, billed amount, and any Explanation of Benefits (EOB) references.
• Authorizations/referrals: Prior auth number, referral ID, and the reason for the service or procedure.
• Pharmacy issues: Drug name, dosage, days’ supply, pharmacy name and phone, and any prior authorization or step therapy notices.
• Payment questions: How you pay premiums (auto-pay, bank draft, card), last payment date and amount, and any invoice or confirmation numbers.

Common reasons to call and which team handles them

Benefits and coverage questions (deductibles, copays, coinsurance, out-of-network rules) are handled by the member services or concierge team displayed on your ID card. They can also walk you through finding in-network doctors and facilities and schedule provider outreach if something looks misrouted.

Claims and billing issues—like unexpected balances, duplicate bills, or EOB vs. provider invoice mismatches—are typically resolved by the same member services line, sometimes with a warm transfer to the claims team. Have the claim ID and date of service handy. If a provider says an Oscar claim was denied for missing information, ask your concierge to coordinate a re-submission with the provider’s billing office.

Prior authorizations, referrals, and clinical reviews may involve a utilization management team. Your concierge can check status, confirm medical policy criteria, and escalate for a peer-to-peer review if a denial needs reconsideration. Pharmacy prior authorizations often route through the pharmacy benefit manager; your concierge can initiate or track the request.

If you can’t locate your Oscar number or need coverage verification

If you don’t have your card and can’t sign in, use the Contact or Help options at https://www.hioscar.com to request assistance securely. If you’re unsure which plan you’re enrolled in (for example, after moving or changing jobs), the federal Marketplace can confirm enrollment for Marketplace plans, and Medicare can verify enrollment for Medicare Advantage plans.

If you suspect a scam or phishing attempt, don’t provide payment info over the phone—navigate directly to https://www.hioscar.com or the Oscar app, or call the number on your physical ID card.

Language access and accessibility

Oscar provides language assistance for members at no cost. If English is not your preferred language, request an interpreter when you call. You can also ask that written communications be provided in your preferred language or in accessible formats.

For members who are deaf, hard of hearing, or have a speech disability, use Telecommunications Relay Service by dialing 711 and ask the operator to connect you to the member services number shown on your Oscar ID card. Relay calls are accepted during normal business hours, and the 24/7 nurse line typically accepts relay calls as well.
