A medical billing company can handle far more than submitting claims. Depending on the agreement, the scope may include eligibility checks, coding support, payment posting, denial follow-up, accounts receivable management, patient statements, reporting, and several other tasks that keep a practice’s revenue moving.
“Full-service billing” varies by vendor, so practices may face unexpected fees or unworked denials when services and responsibilities aren’t clearly defined.
This guide explains what healthcare billing services typically cover, how they differ from broader revenue cycle management, how pricing can vary by claim volume, and what to review before signing a contract.

What Do Healthcare Billing Services Actually Include?
The services included in a medical billing agreement vary by vendor. Some companies handle the full claim lifecycle from registration through collections. Others focus narrowly on claim submission and leave denial work, A/R follow-up, and patient billing to the practice.
Here’s what’s commonly included and what’s often billed as an add-on.
| Service | What It Covers | Why It Matters | Monitor | Included? |
| Patient Registration & Charge Capture | Patient details, visit data, billable charges | Prevents errors from carrying into claims | Demographic and charge accuracy | Usually |
| Eligibility Verification | Coverage and benefits checks | Catches coverage issues before billing | Timing and exception handling | Usually |
| Medical Coding | CPT, HCPCS, and ICD-10-CM coding | Reduces coding errors, denials, and underpayments | Coder credentials and specialty experience | Varies |
| Claim Submission | Claim creation and payer submission | Gets clean claims to the payer | First-pass acceptance rate | Yes |
| Claim Tracking | Post-submission status checks | Keeps claims from going unresolved | Follow-up frequency and ownership | Usually |
| Payment Posting | Payments and adjustments | Keeps A/R records accurate | Posting turnaround time | Usually |
| Denial Management | Denial review, correction, resubmission, appeals | Helps recover denied revenue | Denial turnaround and recovery | Usually |
| A/R Follow-Up | Payer and patient follow-up on unpaid balances | Helps prevent aging A/R from going unworked | 60-, 90-, and 120+ day A/R | Usually |
| Underpayment Review | Payment-to-contract rate checks | Identifies missed reimbursement | Contract reconciliation | Often add-on |
| Patient Billing | Statements and patient balances | Supports patient collections | Statement timing and support | Usually |
| Appeals | Disputing denied or underpaid claims | Recovers revenue that may otherwise be lost | Appeal scope and turnaround | Varies |
| Reporting & Analytics | A/R, denials, claims, and collection reports | Shows whether billing is performing | KPIs and reporting frequency | Usually |
| Credentialing | Provider enrollment with payers | Supports timely payer billing | Included scope and payer coverage | Often separate |
| Prior Authorization | Payer approval before certain services | Helps prevent authorization-related denials | Required services and tracking | Often separate |
Medical Billing vs. Revenue Cycle Management: What’s the Difference
Medical billing is one part of the broader revenue cycle. Billing typically covers claim submission, payment posting, denial follow-up, A/R follow-up, and patient billing. Revenue cycle management covers the financial process from the patient’s initial encounter through payment collection, although the exact scope can vary by organization.
A company advertising “full-service billing” isn’t necessarily managing the entire revenue cycle. The labels alone don’t tell you what’s covered.
| Medical Billing | Revenue Cycle Management | |
| Core focus | Claims through payment collection | Scheduling through final payment |
| Typical scope | Submission, posting, denials, A/R, patient billing | Billing scope plus eligibility, prior auth, coding, credentialing, reporting |
| Best fit for | Practices handling front-end tasks internally | Practices wanting one vendor managing the full cycle |
The key difference is how much of the revenue cycle the vendor actually manages. Before choosing a provider, confirm which tasks are included and which remain with your practice.
How to Choose a Medical Billing Services Company: What to Check Before Signing
Choosing a right medical billing company comes down to a defined set of criteria rather than a general impression of professionalism or price. These factors will tell you what actually distinguishes a reliable billing partner from one that looks capable on a sales call but performs differently once the contract starts.
- Specialty Experience: Confirm the vendor regularly handles your specialty’s coding and billing requirements. Ask: How many providers do you currently bill for in our specialty?
- Payer Experience: Check whether the vendor has active experience with your major commercial, Medicare, and Medicaid payers. Ask: Which of our top payers do you currently handle?
- Service Scope: Get a written list of services included in the quoted fee and identify anything billed separately. Ask: What services cost extra?
- Denial Management: Review how the vendor identifies, corrects, appeals, and tracks denied claims. Ask: What happens after a claim is denied?
- A/R Follow-Up: Confirm how often aging accounts are reviewed and when unpaid claims receive escalated follow-up. Ask: When does an account get escalated?
- Reporting and KPIs: Verify that reports cover metrics such as denial rate, days in A/R, and net collection rate. Ask: Which reports will we receive?
- System Compatibility: Confirm compatibility with your current EHR, practice management system, and clearinghouse before signing. Ask: Will your team work with our existing systems?
- Coding Credentials: Check whether coders hold relevant credentials and understand your specialty’s coding requirements. Ask: Are your coders AAPC-certified and specialty-experienced?
- Compliance and Security: Verify HIPAA-compliant data handling, access controls, encryption, and a signed Business Associate Agreement. Ask: Can you provide your BAA and security policies?
- Point of Contact: Confirm whether your practice will have a consistent contact who understands your account. Ask: Who will handle our account day to day?
- Pricing Structure: Identify whether fees use collections, flat rates, per-claim charges, or hybrids, including additional costs. Ask: What fees fall outside the base price?
- Contract Terms: Review contract length, termination notice, data return, and open A/R responsibilities before signing. Ask: What happens to our data and unpaid claims after termination?
Healthcare Billing Services Cost: Pricing Models Explained
Medical billing companies commonly charge as a percentage of collections, per claim or encounter, through a flat monthly fee, or through a combination of these models. When comparing the cost of medical billing services, look at the total cost and included services, not just the quoted rate.
Percentage of Collections
The vendor charges a percentage of the collections covered by the agreement. Ask whether services such as coding, denial management, and A/R follow-up are included or billed separately.
Per-Claim or Per-Encounter
You pay a set fee for each claim or encounter processed. Because the fee is tied to claim volume rather than collections, ask how denial follow-up, appeals, and A/R work are handled and priced.
Flat Monthly Fee
You pay a fixed amount each month regardless of collections. This can make budgeting easier, but check whether the fee changes when claim volume or provider count increases.
Hybrid Pricing
Some vendors combine pricing methods, such as a percentage of collections plus separate fees for specific services. Ask for the complete fee structure before signing.
Additional Fees to Check
Depending on the contract, you may also encounter:
- Setup fees: One-time implementation or onboarding charges
- Minimum fees: Monthly charges that apply below a specified threshold
- Coding fees: Separate charges when coding is not included
- Credentialing fees: Charges for provider or payer enrollment
- Statement fees: Charges for patient statements
- A/R cleanup: Additional fees for working older unpaid accounts
- Appeal fees: Separate charges for certain denial appeals
Compare the Total Cost
For percentage-based pricing, calculate the fee against your expected monthly collections. For example, a 6% fee on $50,000 in collections equals $3,000, while the same rate on $150,000 equals $9,000.
The right model depends on your collection volume, service scope, and billing workload. Compare the total fee, included services, and additional charges before choosing a proposal.
Which Billing Approach Fits Your Practice?
The right billing setup depends on the specific problem your practice is trying to solve, not a general preference for outsourcing or keeping billing in-house.
High Denial Rate
If denials are a recurring problem, prioritize a vendor with a documented denial management process, not just a general claim submission service. Ask specifically how denials are categorized by root cause and how appeals are handled.
Significant Aging A/R
If a large portion of your A/R sits past 90 days, prioritize a vendor with strong A/R recovery processes and clear reporting on aging accounts. A vendor that only submits new claims well won’t necessarily be equipped to work through a backlog.
Limited Administrative Staff
Billing services for private practices can help practices with limited staff manage eligibility checks, coding, denial follow-up, and reporting without adding to their internal workload.
Capable Billing Team That Struggles With Follow-Up
If your internal team handles most billing well but struggles specifically with denial follow-up or aging A/R, a specialized service focused on those functions may be a better fit than replacing your entire billing operation.
Rapidly Growing Practice
If patient volume and claims are increasing quickly, look for a vendor that can scale staffing and processes with you, rather than one sized for your current volume alone. Ask directly how the company handles sudden increases in claim volume.
In-House vs. Outsourced Medical Billing: Which Is Right for Your Practice?
The best billing model depends on your practice’s staffing, claim volume, in-house expertise, and ability to manage billing tasks consistently.
| Billing Model | Best Fit For | Main Trade-Off |
| In-House | Practices with experienced billing staff and enough volume to support them | Practice handles staffing, training, technology, and oversight |
| Outsourced | Practices with limited billing expertise or staff capacity | Less day-to-day control and greater reliance on the vendor |
| Hybrid | Practices that want to keep some billing tasks in-house and outsource others | Requires clear responsibilities between the practice and vendor |

Conclusion
Healthcare billing services can handle claims, payments, denied claims, unpaid balances, patient bills, and reporting. Some companies also provide coding, eligibility checks, and other billing tasks. Since every vendor includes different services, check exactly what you are paying for, what costs extra, how unpaid claims are handled, and what reports you will receive.
The right choice depends on your practice’s needs. If your staff already handles most billing work, you may only need help with denials or unpaid claims. If billing takes too much staff time, outsourcing more of the work may make sense. Compare in-house, outsourced, and hybrid options based on your workload, budget, and the level of support you actually need.
