Fee for service (FFS)

Fee-for-service (FFS) is a billing model in which individuals, businesses, or organizations are paid for individual, itemized services they provide to clients, rather than receiving flat-fee, lump-sum compensation for a suite of related services. While FFS models are most commonly associated with privatized healthcare systems, they are also occasionally used in real estate and other for-profit and nonprofit industries.

In healthcare contexts, FFS billing models are sometimes alternately referred to as indemnity plans. While FFS models are becoming less common in the healthcare industry, fee-for-service remains a definitive feature of the traditional Medicare plan, which millions of Americans still use as their primary form of health insurance coverage.

Overview

FFS health insurance billing models allow policyholders to see any doctor they wish and to be treated at any hospital they choose, so long as the doctor or hospital accepts the policyholder's plan. Bills are itemized and include lists that detail each specific service the patient received. For example, consider a case in which a patient sees a doctor for a broken arm. Under an FFS model, the patient's bill would be itemized to specify each service as a distinct entity with an associated cost. The doctor's consultation fee, the patient's X-ray, and the application of the cast would all be listed separately, rather than billed as a single flat-fee charge covering all provided services. Patients are then responsible for paying their bills themselves, after which they file a claim with their insurance providers for reimbursement.

In real estate, FFS billing models are sometimes used by agents and realtors as an alternative to charging their clients a fixed percentage of a property's sale price in exchange for their services. When they are used, these billing models are usually structured around a list of services the agent or realtor is able to perform, with specific prices accompanying each service. The client then chooses the specific services he or she wants from the agent or realtor. For example, in the case of a client selling a property through an agent or realtor on an FFS billing basis, the agent or realtor may impose a fixed fee each time he or she shows the property to a prospective buyer. The negotiation of the property's final sale price would also be billed as a separate service and would be charged either at a flat rate or billed as a percentage of the price the buyer agrees to pay.

FFS models can also be used in virtually any other situation in which an individual or organization provides a set of related but separate services to a customer or client. For instance, a children's day camp may use FFS billing models that allow participants to opt in or opt out of particular activities by attaching fees to each program offered at the camp. Campers then pay only for the activities in which they took part, rather than paying a fixed, preset rate for attending the camp. Public universities, state parks, national parks, and nonprofit organizations that generate revenues through memberships are examples of other entities that may use FFS billing models.
