Eligibility and Verification
US Medical Billing verifies each patient's coverage and benefits before they are seen — running 270/271 eligibility checks, flagging prior-authorization and referral requirements, and estimating what the patient will owe — so avoidable denials are stopped before a claim is ever created.
- Coverage confirmed before the visit
- 270/271 eligibility checks
- Prior-auth and referral flags
- Patient responsibility estimated up front
What eligibility and verification does
Eligibility verification confirms that a patient's insurance is active and covers the planned service before that service is delivered. It answers the questions that decide whether a claim will be paid: is the plan in effect on the date of service, is the provider in network, what are the copay, coinsurance, and deductible amounts, and does the service require a prior authorization or referral.
Most of what a payer will later reject can be seen at this stage. Terminated coverage, coordination-of-benefits conflicts, and missing authorizations become denials only because they were not caught before the visit. Verifying up front turns those would-be denials into a phone call or a corrected field.
US Medical Billing runs this as the first, connected step of your revenue cycle — checking eligibility electronically and through payer portals, resolving what the response leaves ambiguous, and handing the front desk a clear benefit summary and patient estimate before the patient arrives.
Who it's for
Eligibility work protects revenue wherever coverage changes often or the cost of an unverified visit is high.
Practices with high front-end denial rates
If a meaningful share of denials trace back to inactive coverage, coordination of benefits, or missing authorizations, the fix belongs before the visit — not in appeals.
High-deductible and plan-switching populations
When patients change plans at renewal or carry large deductibles, benefits verified in advance keep estimates accurate and collections realistic.
Services that require prior authorization
Imaging, procedures, and specialty care where a missing precertification means a full denial benefit most from requirements being flagged at scheduling.
What's included
Verification is more than a yes/no coverage check. These are the capabilities that make up the service.
Coverage confirmation
Confirm the plan is active on the date of service and that the patient and provider relationship is valid, using real-time 270/271 checks and payer portals.
Benefit detail capture
Pull copay, coinsurance, deductible met and remaining, out-of-pocket status, and service-specific benefits — not just an active/inactive flag.
Network and plan-type checks
Verify in-network versus out-of-network status and plan type (HMO, PPO, EPO) so the visit is billed under the right terms.
Prior-authorization and referral flags
Identify which planned services require precertification or a referral, and surface those requirements before the appointment rather than after the denial.
Coordination of benefits
Determine primary versus secondary payer and surface unresolved coordination-of-benefits conflicts that would otherwise reject the claim.
Patient responsibility estimation
Translate confirmed benefits into an estimate of what the patient is likely to owe, so the front desk can discuss cost before the visit.
Exception handling
Work the cases the automated response cannot resolve — mismatched IDs, ambiguous 271 responses, and inactive plans — before they reach scheduling.
How verification works
Follow a scheduled visit from the appointment list to a benefit summary the front desk can act on.
Intake from the schedule
Upcoming appointments, patient demographics, and insurance details are pulled from the schedule ahead of the date of service.
Inputs and outputs
Verification takes the schedule and the patient's coverage details and returns a decision-ready summary for each visit.
What you provide
- Appointment schedule with patient demographics and visit dates
- Insurance details: payer, member or subscriber ID, and group number
- Rendering provider and place-of-service information
- Planned procedures or CPT/HCPCS codes where known
- Payer connectivity through a clearinghouse or portal access
What you get back
- A benefit summary per patient: active coverage, plan type, and network status
- Cost-share detail: copay, coinsurance, deductible met and remaining, out-of-pocket status
- Prior-authorization and referral flags with the specific requirement
- Primary and secondary payer order with coordination-of-benefits notes
- A patient responsibility estimate and an exceptions list for coverage that could not be confirmed
Responsibilities and boundaries
An honest split of what verification handles, what is shared with your team, and what stays with the practice.
We handle
- Running 270/271 eligibility checks and payer-portal verification before the visit
- Interpreting the 271 response into a clear, usable benefit summary
- Flagging prior-authorization and referral requirements for planned services
- Estimating patient responsibility from confirmed benefits
Shared
- Collecting accurate insurance and demographic information at scheduling and registration
- Deciding how and when patient cost estimates are communicated to patients
- Agreeing which services and appointment types are verified in advance
You keep
- Clinical decisions about which services a patient needs
- The clinical documentation that supports a prior-authorization request
- Point-of-service collection of the amounts patients owe
Common process failures
Most front-end denials come from a handful of predictable gaps. Each is what the stage exists to prevent.
Coverage assumed, not re-verified
A plan that was active last visit has since terminated or changed, and the claim comes back as expired or inactive coverage (CARC CO-27). Verifying every visit close to the date of service, rather than trusting the record on file, catches it first.
Missing prior authorization
A service required precertification that was never obtained, and the payer denies for absent authorization (CARC CO-197). Flagging the requirement at scheduling gives the practice time to secure the authorization before the service is delivered.
Coordination-of-benefits conflict
The wrong payer is billed first, or the patient's coordination of benefits is unresolved at the payer, producing an other-insurance denial (CARC CO-22). Confirming primary versus secondary before the visit resolves the order up front.
Wrong plan or transposed member ID
A mistyped subscriber ID or the wrong payer selection causes the 270 to return no match, so the visit is never truly verified. Validating demographics and payer selection against the response keeps the check meaningful rather than a formality.
Reporting and visibility
What your practice can see across the verification stage — the status of the work, not invented metrics.
Verification status by appointment
See which upcoming visits are verified, pending, or flagged, so the front desk knows where a coverage problem still needs attention.
Authorization tracking
Track which planned services require prior authorization or a referral and where each requirement stands ahead of the visit.
Exceptions and patterns
Review inactive-coverage, coordination-of-benefits, and missing-authorization exceptions surfaced before the visit, and the patterns behind recurring front-end issues.
What to expect
How we approach the work — these describe the service, not guaranteed outcomes.
Caught before the claim exists
Coverage, authorization, and coordination-of-benefits problems are worked before the visit, where they are a correction rather than a denial and appeal.
The whole 271, not just active/inactive
Benefit detail is read and interpreted so the front desk has real numbers — deductible remaining, coinsurance, network status — not a bare coverage flag.
Requirements surfaced with time to act
Prior-authorization and referral requirements are flagged early enough that the practice can secure them before the date of service.
Estimates the front desk can use
Confirmed benefits are turned into a patient responsibility estimate, so cost conversations happen before the visit instead of after the statement.

Frequently asked questions
What is the difference between eligibility verification and prior authorization?
Eligibility verification confirms that a patient's plan is active and shows the benefits that apply — network status, copay, coinsurance, and deductible. Prior authorization is a separate approval the payer requires before certain services, confirming it will cover that specific service. Verification is where we identify that an authorization is required; the two are related but not the same, and a plan can be active while a service still needs authorization.
How close to the visit should eligibility be checked?
Close enough that the coverage on file is still true on the date of service. Plans terminate, change, and switch at renewal, so a check run well ahead can be stale by the appointment. Verifying in the days before the visit — and re-checking when coverage is known to be changing — keeps the result meaningful rather than a formality.
Do you obtain prior authorizations, or only flag when they are needed?
Verification identifies when a planned service requires prior authorization or a referral and surfaces the specific requirement before the visit. Whether the team also pursues and secures the authorization depends on the scope agreed with your practice, because the request relies on clinical documentation that comes from the provider. We will be explicit about which of these we handle for you.
How is patient responsibility estimated?
From the benefits the payer returns: the copay for the visit, coinsurance percentage, and how much of the deductible and out-of-pocket maximum remains. Applied to the planned service, those give an estimate of what the patient is likely to owe. It is an estimate, not a final figure — the actual amount is set when the payer adjudicates the claim — but it lets the front desk have an informed cost conversation before the visit.
