For a two-physician primary care practice, medical billing is rarely a single person’s full-time job — and that’s exactly the problem. The billing gets done alongside scheduling, patient intake, and phone calls, which means it gets done inconsistently. Claim submission slows down, follow-up on unpaid claims doesn’t happen on schedule, and denial management falls through the cracks. By the time someone notices the A/R is aging, the damage is already done.
Outsourcing to a medical billing company is the most common fix — but choosing the wrong one trades one set of problems for another. This guide covers what medical billing companies actually do, how they price their services, and the specific criteria small practices should use to evaluate options before signing a contract.
Why Small Practices Struggle With In-House Medical Billing
In-house billing works when you have dedicated, trained staff with the bandwidth to manage claims end to end. Most small practices don’t. The problems that emerge are predictable:
- Staffing is thin — one person out sick means claims pile up for days
- Coders and billers need specialty-specific training that’s expensive to maintain and easy to lose to turnover
- Billing software licenses, clearinghouse fees, and compliance updates carry ongoing costs that scale poorly for small volumes
- Keeping up with payer-specific rules, CPT and ICD-10 updates, and CMS policy changes requires continuous training
The financial impact is measurable. MGMA data shows that practices with optimized revenue cycle performance collect significantly more per physician than the median, with the gap often traced to claim submission timeliness and denial follow-through — two areas where thin in-house teams consistently fall short.
What Medical Billing Companies Actually Do
Before evaluating vendors, it helps to have a clear picture of what is and isn’t typically included in a billing service contract. Core services generally include:
- Charge capture review and claim submission to payers
- Eligibility verification and benefit checking before service
- Denial management — identifying, appealing, and resubmitting rejected claims
- Payment posting — recording EOBs and patient payments to accounts
- Patient billing and statement generation
- Monthly reporting on collections, denial rates, days in A/R, and clean claim rate
Services that may or may not be included depending on the vendor and contract tier: coding review and audit support, credentialing and provider enrollment, prior authorization follow-up, and practice management consulting. Confirm scope in writing before signing.
Comprehensive Benefits of Outsourcing Medical Billing Service
The following most common benefits collectively contribute to a more streamlined, efficient, and financially secure practice, allowing healthcare providers to focus on enhancing patient care instead.
- Cost Savings: Outsourcing eliminates the need for an in-house billing department, significantly reducing overhead costs associated with salaries, training, and technology maintenance. This shift can free up resources that can be better invested in patient care or practice expansion.
- Enhanced Revenue Cycle Management: By outsourcing, practices benefit from specialized expertise in billing that ensures faster claim submissions and reduced incidences of claim denials. This leads to improved cash flow and quicker revenue realization.
- Compliance and Accuracy: Outsourced billing services stay abreast of the latest healthcare regulations, including HIPAA compliance, ensuring that billing practices meet all legal requirements. This compliance reduces the risk of costly legal issues and helps maintain the privacy and security of patient data.
- Avoiding Billing and Coding Errors: Professional billing companies use sophisticated medical billing software and skilled coders to reduce the likelihood of errors. Accurate coding minimizes the chances of claim rejections and denials, directly impacting the bottom line positively.
- Operational Efficiency: With the administrative burden of billing shifted to experts, healthcare providers can focus more on patient care and other core activities, improving overall practice performance and patient satisfaction.
- Enhanced Patient Trust and Satisfaction: Efficient billing processes and transparent communication from outsourcing firms can increase patient trust. Patients appreciate accurate and prompt billing experiences, which enhance their overall satisfaction with the healthcare provider.
In-House Billing vs. Outsourcing: Side-by-Side Comparison
Factor | In-House Billing | Outsourced Billing |
Cost structure | Fixed: salaries, software licenses, training, clearinghouse fees | Variable: percentage of collections or flat monthly fee — scales with practice volume |
Expertise | Dependent on individual staff knowledge; vulnerable to turnover | Team of dedicated billers and coders with specialty experience |
Technology | Practice funds and maintains its own billing software and integrations | Vendor provides and maintains billing platform; practice needs EHR integration |
Compliance updates | Practice responsible for keeping staff current on coding changes | Vendor manages CPT, ICD-10, and payer policy updates |
Visibility | Direct oversight of billing activity day-to-day | Access through vendor portal and monthly reports — varies by vendor |
Scalability | Adding providers requires hiring and training additional staff | Vendor scales capacity; no added headcount for the practice |
Control | Full control over billing decisions and payer communication | Dependent on vendor responsiveness; SLAs govern turnaround |

Medical Billing
How Medical Billing Companies Are Typically Priced
Understanding pricing models before entering a vendor conversation helps you compare apples to apples. Three structures are common:
Percentage of collections (most common for small practices). The vendor charges 4–9% of what is actually collected, not billed. The range varies by specialty — high-complexity specialties with larger claim values and more denials often pay at the lower end of the range; high-volume, lower-complexity practices may see higher rates. The advantage: vendor incentives are aligned with your collections. The risk: ensure the contract specifies what ‘collections’ includes.
Flat monthly fee per provider. A fixed amount per physician, regardless of volume or collections. Predictable budgeting, but the vendor has less direct financial incentive to maximize your collections.
Per-claim pricing. Less common, typically used for high-volume, simple billing scenarios. A fixed fee per claim submitted — straightforward but can become costly if rework and resubmissions are counted as additional claims.
Ask any vendor to show you exactly how their fee is calculated, what is excluded, and whether setup, clearinghouse, or report generation fees are billed separately.
What to Look for When Choosing a Medical Billing Company
The following criteria table covers the evaluation dimensions that matter most for small practices. Use it to structure vendor conversations and compare responses consistently.
Criteria | What to Ask | Benchmark / What Good Looks Like |
Specialty experience | Do you have current clients in our specialty? Can you provide references? | Vendor should have active clients in your specialty, not just general experience |
First-pass claim acceptance rate | What is your average first-pass acceptance rate across your client base? | 95% or higher. Below 90% is a red flag. |
Denial rate | What is your average denial rate, and what is your appeal rate? | Denial rate below 5%; appeal/overturn rate above 60% |
Days in A/R | What is the average days in A/R for practices similar to ours? | Under 35 days for clean claims; under 50 days overall |
EHR/PMS integration | Which practice management systems do you integrate with? Is there an integration fee? | Native integration with your current EHR; no manual data export required |
Reporting access | Will we have real-time access to a reporting portal? What reports are included? | On-demand access to denial reports, A/R aging, collection rate, and monthly summaries |
HIPAA compliance | Do you have a signed BAA process? Where is PHI processed and stored? | Signed BAA required. Offshore billing teams must also be covered under BAA. |
Coding support | Is coding review included, or is that a separate service? | At minimum, coding audit flagging. Full coding services should be scoped clearly. |
Contract terms | What is the contract length? What are the termination terms? | Month-to-month or annual with 30–60 day notice. Avoid multi-year lock-ins with no exit clause. |
Transition support | If we leave, how is data returned and what is the transition process? | Full data export in standard format; no hostage data. Transition support documented in contract. |
Red Flags to Watch Out For
Not every billing company will surface problems in the sales conversation. Watch for these signs before signing:
- No SLA guarantees in writing. If a vendor won’t commit to turnaround times, denial response windows, or clean claim rate benchmarks in the contract, those promises don’t exist.
- Reluctance to share denial rate data. Any established billing company should be able to produce aggregated denial rate and collection rate data for their client base. Vague answers here are a red flag.
- No specialty-specific references. General billing experience does not transfer cleanly to specialty billing. An orthopedic practice and a behavioral health practice have fundamentally different coding requirements.
- Long lock-in contracts with punitive exit terms. A vendor confident in their performance will offer reasonable termination terms. Multi-year contracts with high early-exit penalties shift risk entirely to the practice.
- Offshore billing without HIPAA BAA coverage. Offshore teams are not inherently a problem — but PHI handling must still be covered under a signed Business Associate Agreement. If it isn’t, that’s a compliance exposure.
- No real-time reporting portal. Monthly PDF summaries are not sufficient. You should have on-demand access to your practice’s financial data.
Specialty-Specific Billing Considerations
Billing complexity varies significantly by specialty, and the right vendor should demonstrate familiarity with yours. A few examples of where specialty-specific experience matters:
Oncology. Chemotherapy administration billing involves multiple CPT codes per encounter — drug codes, administration codes, and supportive care codes that often change with treatment phase. Errors here result in underpayment or denials that are time-consuming to appeal.
Behavioral health. Payer coverage for mental health services varies widely, and many payers have carved out behavioral health to separate managed care organizations. Billers unfamiliar with behavioral health carve-outs will submit to the wrong payer and generate avoidable denials.
Orthopedics. Procedures like joint replacements and arthroscopies require detailed post-operative care billing with appropriate global period tracking. Unbundling errors and global period violations are common without specialty-trained billers.
Primary care. High visit volume and annual wellness visit billing (AWV vs E&M) require billers who understand preventive versus problem-focused service distinctions, especially as Medicare Annual Wellness Visit billing has its own documentation requirements.
When vetting vendors, ask specifically about their experience with your specialty’s denial patterns and coding nuances — not just general RCM capability.
Conclusion
Choosing a medical billing company is a financial and operational decision, not just an administrative one. The right partner improves your clean claim rate, reduces denial backlog, and gives you accurate data to manage practice finances. The wrong one creates new problems while obscuring the old ones behind a reporting lag.
Before signing anything, run through the criteria table above with every vendor you consider. Ask for denial rate data, request references in your specialty, and read the contract termination terms before you read the pricing page.

Frequently Asked Questions
What does a medical billing company do?
A medical billing company manages the administrative process of submitting insurance claims, following up on unpaid claims, appealing denials, posting payments, and generating patient statements. Many also offer coding review, eligibility verification, and monthly financial reporting. Scope varies by vendor — confirm what is included in writing before signing.
How much do medical billing companies charge?
Most charge a percentage of collections — typically 4 to 9 percent depending on specialty and practice volume. Flat monthly fees per provider and per-claim pricing are less common alternatives. Ask vendors to clarify what ‘collections’ includes in their fee calculation and whether any additional fees (setup, clearinghouse, reporting) apply separately.
Is outsourcing medical billing worth it for a small practice?
For most small practices, yes. In-house billing requires salaries, ongoing training, software licensing, and compliance management — fixed costs that are disproportionately burdensome at low provider counts. Outsourcing converts most of that to a variable cost tied to performance and typically improves clean claim rates and days in A/R when the right vendor is selected.
What should I look for when choosing a medical billing company?
Start with first-pass claim acceptance rate (95%+ is the benchmark), denial rate and appeal performance, specialty-specific experience, EHR integration capability, real-time reporting access, and contract termination terms. Ask for client references in your specialty, not just general testimonials.
What are red flags when evaluating a medical billing company?
No SLA commitments in writing, reluctance to share denial rate data, no specialty-specific references, long lock-in contracts with punitive exit terms, offshore billing without a signed HIPAA BAA, and no real-time reporting portal. Any of these should prompt further scrutiny before signing.
