Medical Billing and Insurance Claims

Medical billing and insurance claims are the processes that ensure healthcare providers receive payment for services while patients pay only their covered share. Providers submit detailed claims to insurers using standardized forms like CMS-1500 for professional services or UB-04 for facilities, detailing procedures with medical codes. This system applies across private insurance, Medicare, Medicaid, and federal programs like TRICARE For Life, which covers cataract surgery after Medicare with specific copays and prior approvals.

Key Steps in the Claims Process

The process starts with patient registration, where providers collect demographics and verify insurance eligibility to confirm active coverage and benefits. During the visit, services are documented and coded accurately. Bills are then scrubbed for errors before electronic submission to payers, often via clearinghouses for high-volume insurers like Medicare.

Review, Payment, and Denials

Insurers adjudicate claims by checking medical necessity, authorizations, and policy terms, issuing payment, an Explanation of Benefits (EOB), or denial. Patients receive the EOB detailing covered amounts, provider payments, and remaining balances like deductibles or copays. Denied claims can be appealed with additional documentation; federal programs have strict timelines, such as Medicare’s 12-month filing limit.
