Fee-for-service
A payment model in which a provider is paid a discrete fee for each specific service performed. Each office visit, procedure, test, or treatment generates a separate billable claim. Revenue scales directly with the number of services delivered. This is the dominant payment model for most independent outpatient clinics in the United States.
Why this matters for your clinic
Fee-for-service is how most clinic owners get paid, which means every financial decision in the practice — staffing levels, scheduling density, payer contracting, coding accuracy — connects back to the per-service economics. Understanding FFS means understanding that your revenue is a function of volume multiplied by reimbursement rate per service. When revenue is flat, it is either a volume problem or a rate problem.
The primary financial risk in FFS is revenue volatility. A week with fewer patients, a surge in denials, or a slow payer is immediately visible in collections. There is no guaranteed monthly base payment. Cash flow management under FFS requires close attention to AR trends and a sufficient operating reserve to absorb monthly variation.
As CMS pushes more beneficiaries into value-based arrangements, purely FFS practices face increasing pressure to layer on quality reporting and performance metrics. Understanding FFS deeply is the prerequisite to understanding what changes if and when your payers shift you toward alternative payment models.
What good looks like
Per the HCPLAN APM Measurement Report, roughly 42% of traditional Medicare dollars still flow through fee-for-service arrangements (as of 2023 data). For commercial payers, FFS remains dominant in most outpatient specialties, particularly dental, PT, chiropractic, and mental health. CMS has publicly targeted moving all Medicare beneficiaries into accountable care relationships by 2030, which will gradually reduce pure FFS exposure in Medicare-heavy practices.
Example
A physical therapy practice operates on FFS. A therapist sees 12 patients per day at an average net reimbursement of $95 per visit. That is $1,140 per day per therapist, or roughly $285,000 per year per full-time therapist before overhead. If patient volume drops to 10 per day due to scheduling inefficiency, revenue per therapist falls to $237,500 — a $47,500 annual reduction per provider with no change in overhead.
From Sorso
For most $3M-$10M independent clinics, FFS will remain the primary payment model for the foreseeable future. The financial planning priority is optimizing the FFS engine — clean claims, strong AR management, good payer contracts — before adding complexity from alternative payment models.
