Healthcare billing isn’t a single process. It splits into two separate dimensions that practice managers need to understand independently: the payment model that determines how a practice gets paid (fee-for-service, value-based, bundled, capitation, or concierge billing), and the claim structure that determines how that payment is actually submitted and processed (professional billing versus institutional billing, and inpatient versus outpatient billing). A practice’s financial risk, revenue predictability, and administrative workload all shift depending on which combination of payment model and claim structure applies. Practices juggling several of these models at once often rely on a dedicated medical billing services team to keep every claim type coded and submitted correctly.
This guide breaks down both dimensions so practice managers can see exactly how each type of billing affects revenue and operations differently. Many practices find it easier to make sense of this complexity with the support of an experienced medical billing services team rather than managing every model in-house.
Billing by Payment Model
The payment model determines how a practice earns revenue and how financial risk is distributed between the provider and the payer.
| Model | How It Works | Financial Risk |
|---|---|---|
| Fee-for-Service (FFS) | Providers bill separately for each service, test, or procedure performed | Low risk for the provider; higher cost risk for the payer, since volume drives revenue |
| Value-Based Billing | Payment is tied to quality of care and patient health outcomes, with bonuses or penalties attached | Higher risk shifts to the provider to manage outcomes efficiently |
| Bundled Payments | A single fixed payment covers all services for a defined episode of care, such as a joint replacement | Risk is shared among all treating providers and facilities if the episode goes over budget |
| Capitation | Providers receive a fixed monthly payment per enrolled patient, regardless of how much care that patient uses | Provider carries the risk if a patient needs significant care; benefits if the patient stays healthy |
| Retainer / Concierge Billing | Patients pay a direct subscription fee for enhanced access to care, outside the standard insurance billing model | Low financial volatility, but the total patient panel size is limited by design |
Fee-for-service remains the most common model for individual claims processing, which is why most of a billing team’s day-to-day coding and claims work is built around it. Value-based and bundled models introduce additional reporting and quality-tracking requirements on top of standard claims submission, since payment depends on more than just the service delivered. Seeing how that day-to-day coding actually plays out is easier with real scenarios, such as those walked through in this medical coding examples guide.
Billing by Claim Type: Professional vs. Institutional
Independent of the payment model, healthcare billing also splits by who is being billed for and what claim form is used.
Professional billing (also called physician billing) covers the specific services a clinician personally delivers, submitted on a CMS-1500 form using CPT and HCPCS codes. This claim reflects the physician’s time, skill, and medical decision-making, tied to that provider’s National Provider Identifier.
Institutional billing (also called facility or hospital billing) covers the resources a hospital or facility provides, such as the room, equipment, supplies, and support staff, submitted on a UB-04 form using revenue codes and, for inpatient procedures, ICD-10-PCS codes.
Many outpatient visits at hospital-affiliated clinics generate both a professional claim and an institutional claim for the same visit, which is one of the most common sources of confusion for patients who receive two separate bills. Practice managers overseeing both physician and facility-based operations need billing staff fluent in both claim types, since the coding logic and required documentation differ meaningfully between them, and documentation gaps of this kind are covered in more detail in this guide on how billing notes prevent denials.
Billing by Care Setting: Inpatient vs. Outpatient
A related but distinct distinction is whether the billing reflects inpatient or outpatient care, which affects both the claim structure and the specific coding rules that apply.
Inpatient billing applies when a patient is formally admitted to a facility, and it relies on ICD-10-PCS procedure codes alongside diagnosis-related group (DRG) classifications that determine facility reimbursement for the full admission. Outpatient billing applies to same-day visits, procedures, and services that don’t involve formal admission, and it relies primarily on CPT and HCPCS codes rather than DRG classification.
This distinction matters operationally because inpatient and outpatient claims are reviewed under different medical necessity standards, and a service billed under the wrong setting classification can be denied even if the clinical care itself was appropriate. Staff responsible for capturing that setting accurately in the record often ask is EMR certification worth it, since correct documentation at the point of care is what ultimately supports the right classification.
How These Billing Types Interact in Practice
A single practice often manages more than one billing type at once. A physician group might bill fee-for-service for most visits while also participating in a value-based contract with a specific payer for chronic disease management. A hospital-affiliated outpatient clinic generates both professional and institutional claims for the same visit. Understanding which combination applies to a given claim, and which coding rules and documentation standards go with it, is the foundation of a clean claims process.

Choosing the Right Billing Approach for Your Practice
Practice managers evaluating billing structure should weigh a few factors specific to their situation:
- Revenue predictability needs. Capitation and concierge models offer steadier income but cap upside, while fee-for-service ties revenue directly to volume.
- Administrative capacity. Value-based and bundled payment models require more ongoing quality reporting and coordination across providers than standard fee-for-service billing.
- Payer mix. Medicare, Medicaid, and commercial payers each apply these models differently, and a practice’s payer mix often determines which models are realistically available.
- Facility affiliation. Practices affiliated with a hospital or operating in a hospital outpatient department need billing staff who can manage both professional and institutional claims accurately.
How YTC Healthcare’s Team Handles This
Different billing types require different coding logic, documentation standards, and reporting requirements, and a practice managing more than one type at once needs a billing team that can keep those distinctions consistent across every claim. YTC Healthcare’s Medical Billing and Coding team codes claims according to the specific payment model and claim structure that applies, whether that’s standard fee-for-service coding, professional billing tied to a specific provider’s NPI, or claims requiring the quality and outcomes documentation that value-based contracts demand. The Compliance and Reporting team supports the additional reporting requirements that value-based and bundled payment models require, keeping that separate from standard fee-for-service claims processing, and staff supporting this work often build on the fundamentals covered in this EMR training guide. The Revenue Cycle Management team tracks claims across whichever payment model and claim type applies, so practices with a mixed billing structure get consistent oversight rather than treating every claim the same way, a path that often mirrors the kind of progression outlined in this EHR specialist career guide. This structured approach is part of how YTC Healthcare supports its physician billing clients toward its internal benchmark of 95% or higher first-pass claim acceptance and accounts receivable under 40 days.
FAQ
What are the main types of billing in healthcare?
Healthcare billing splits into payment models (fee-for-service, value-based, bundled, capitation, and concierge billing) and claim structures (professional versus institutional billing, and inpatient versus outpatient billing), each governed by different rules.
What is the difference between fee-for-service and value-based billing?
Fee-for-service pays a provider for each individual service delivered, tying revenue to volume, while value-based billing ties payment to quality of care and patient outcomes, shifting more financial risk onto the provider.
What is the difference between professional billing and institutional billing?
Professional billing covers a clinician’s personally delivered services, billed on a CMS-1500 form using CPT and HCPCS codes, while institutional billing covers a facility’s resources, billed on a UB-04 form using revenue codes.
Why do some patients get two separate bills for one visit?
This typically happens with outpatient visits at hospital-affiliated clinics, where the physician’s professional work and the facility’s overhead are billed as two separate claims covering the same visit.
What is capitation billing?
Capitation pays a provider a fixed monthly amount per enrolled patient, regardless of how much care that patient actually uses, creating predictable income but shifting financial risk to the provider for high-need patients.
How does inpatient billing differ from outpatient billing?
Inpatient billing applies to formally admitted patients and relies on ICD-10-PCS codes and DRG classification, while outpatient billing applies to same-day visits and relies primarily on CPT and HCPCS codes.
