Patient Cost Sharing and Commercial Insurance Fundamentals
Every clinical medical assistant needs a firm grasp of health insurance vocabulary to communicate effectively with patients and coordinate office workflows. Commercial coverage may be purchased from a private insurer by an individual or employer; in a self-funded employer plan, the employer bears the claims risk, even if a private insurer administers the plan. Third-party payers refer to entities, such as commercial or government health plans, that reimburse medical claims on behalf of patients. To keep these policies active, a premium must be paid; this is the periodic payment made by a policyholder or employer to maintain health insurance coverage.
When patients receive medical services in an outpatient clinic, they often share the expense through deductibles, copayments, and coinsurance. A deductible is the amount a patient must pay for services subject to the deductible before the plan begins paying for those services, and it typically resets each plan year. A copayment is a fixed dollar amount a patient owes for a covered service, which medical assistants routinely collect at the time of patient arrival and check-in. In contrast, coinsurance is the percentage of the allowed amount for a covered service that the patient owes, generally after any applicable deductible is met.
Many commercial plans include an out-of-pocket maximum for covered in-network care; Original Medicare does not have a general out-of-pocket maximum. This is the most a patient pays in deductible, copayments, and coinsurance for covered in-network services during a plan year, though premiums generally do not count toward this cap. For example, if a patient has already met their out-of-pocket maximum through earlier clinic visits and procedures, the insurer covers the remaining in-network covered services for the rest of that plan year. The medical assistant relays financial and copayment policies to patients within their scope of practice, directing complex disputes to billing specialists.
Common mistakes
- Assuming the parent who is older in age holds the primary policy under the birthday rule; the rule only considers whose month and day of birth falls earlier in the calendar year, not the birth year.
- Attempting to enroll a dependent concurrently in both TRICARE and CHAMPVA, which is expressly prohibited.
- Billing or collecting standard copayments directly from a patient for approved workers' compensation visits, when patients generally must not be charged copays for these approved services.
- Treating an Advance Beneficiary Notice of Noncoverage as a general consent form instead of giving it before a service for an Original Medicare patient when denial is expected for a reason that permits use of the notice.
Key points
- Premiums help maintain coverage; a deductible is itself a form of cost sharing, and some copayments apply before it is met. Copayments are fixed amounts that may be collected at check-in or another time, while coinsurance is a percentage of the allowed amount.
- Managed care plans differ in network restrictions and referral rules: HMOs generally require a PCP and specialist referrals, PPOs generally allow out-of-network care without referrals, and EPOs typically do not require referrals but exclude out-of-network care except for emergencies or plan exceptions.
- Medicare generally covers eligible people aged 65 and older and certain younger people with disabilities, ESRD, or ALS through Parts A, B, C, and D; an Advance Beneficiary Notice of Noncoverage is used for an Original Medicare service only when denial is expected for a reason that permits the notice.
- Medicaid is a state-federal payer of last resort, and when combined with Medicare in dually eligible patients, Medicare is billed first.
- TRICARE and CHAMPVA cannot be held concurrently, and TRICARE eligibility is confirmed through Defense Enrollment Eligibility Reporting System records.
- The birthday rule assigns primary coverage for a dependent to the parent whose birth date falls earlier in the year, unless overridden by a court order, and Remittance Advice forms detail practice claim determinations.
