Outsourced medical billing: What it costs, what to put in the contract, and what changes in your books

Outsourced medical billing hands claim submission and follow-up to an outside company, and it changes how your books reconcile. Numetix reviews billing reports against your deposits and ledger each month. Compare fee models, require a business associate agreement, and keep payments flowing into an account you control.

QUICK ANSWER: WHAT SHOULD YOU KNOW BEFORE OUTSOURCING MEDICAL BILLING?

  • Fees are usually a percentage of collections, a per-claim price, or a flat monthly fee, and each model rewards different behavior and carries different risks.

  • The billing company handles protected health information, so the contract should include a business associate agreement and clear data ownership.

  • Keep payments deposited into an account you control, and reconcile the billing company's reports to deposits and the ledger every month.

Numetix is the expert-led, AI-powered, human-in-the-loop bookkeeping layer for medical and dental practices, so billing reports, deposits, and receivables are reconciled and reviewed by a named person. This guide covers what billing outsourcing includes, how it is priced, what the contract needs, and what it changes in your books.

What does outsourced medical billing include?

Task

What the billing company usually does

Claim preparation and submission

Enters charges, checks claims, and submits them to payers

Payment posting

Applies payer payments and adjustments to patient accounts

Denial follow-up

Works rejected or denied claims and resubmits or appeals

Patient statements

Bills the patient share and tracks balances

Reporting

Produces collections, aging, and denial reports

What the service does not include is bookkeeping. Billing reports describe claims and patient accounts, while the ledger records deposits, fees, and receivables. Many owners assume the two agree. They only agree when someone reconciles them. Our guides to reducing A/R days in a healthcare practice and medical billing myths and denial management cover the operating side.

How is outsourced medical billing priced?

Pricing model

How it works

Watch for

Percentage of collections

A share of what the practice collects

Incentive to chase easy claims over hard ones

Per claim

A set price for each claim submitted

Cost that rises with volume, not results

Flat monthly fee

One price for a defined scope

What the scope excludes

Hourly or project

Time-based work such as cleanup

Open-ended totals

Compare quotes on the same monthly claim volume, and ask for add-on fees, such as setup, statements, or credentialing, in writing so the totals match.

What should the billing contract include?

What Should the Billing Contract Include

A billing company creates, receives, maintains, or transmits protected health information for your practice. The federal HIPAA definition of a business associate covers a person who does that on behalf of a covered entity for functions such as claims processing or administration (45 CFR 160.103), so a written business associate agreement should be in place before any data moves. The HIPAA rules also set what that contract must contain (45 CFR 164.504).

Contract term

Why it matters

Business associate agreement

Sets how protected health information is handled and reported

Payment routing

Payments deposit to your account, not the billing company's

Report access

You can run or receive claims and aging reports on demand

Data ownership and exit

You receive patient account data in a usable format on termination

Transition support

A defined handoff period and notice terms

Performance reporting

Definitions for clean claim rate, denial rate, and days in receivables

What changes in your books when billing is outsourced?

Item

What to check each month

Deposits

Bank deposits match payer remittances and patient payments

Billing company fee

Recorded as an expense and matched to the invoice or statement

Receivables

Aging by payer ties to the balance sheet

Adjustments and write-offs

Recorded and explained, not buried in net revenue

Production versus collections

Reported side by side so trends are visible

This reconciliation is where owners find errors early. Our best bookkeeping service for a medical practice guide describes the monthly routine, and the accounts receivable glossary entry defines the balance you are tracking.

Which numbers should you track once billing is outsourced?

Measure

What it tells you

Clean claim rate

Share of claims accepted on first submission

Denial rate

Share of claims denied by payers

Days in receivables

How long it takes to collect after a claim is sent

Net collection rate

Collected amount as a share of the amount you can expect to collect

Billing fee as a share of collections

Whether the cost of the service is moving with results

Ask the billing company to define each measure in writing, then check the numbers against the ledger. Different companies calculate them differently, so definitions matter more than the headline figure.

In-house or outsourced billing: Which fits?

  • Plan the switch in steps: confirm who owns open claims, set a cutover date, and keep a list of balances moving between systems.

  • Outsource when billing depends on one person, denials are rising, or claims go out late.

  • Keep billing in-house when volume is steady, staff are experienced, and you can supervise follow-up.

  • Either way, keep a bookkeeper reconciling billing reports to deposits and the ledger.

Frequently asked questions

How much do medical billing companies charge?

Companies price by a share of collections, a per-claim fee, a flat monthly fee, or hourly work. The right comparison is total cost on your claim volume, including setup and add-on fees, against collections and denial rates. Ask for the fee schedule in writing and for sample reports before signing.

Should the billing company deposit payments into my account?

Payments should land in an account you control, with the billing company posting and reporting on them. That keeps cash visible to you and makes reconciliation straightforward. If a contract routes funds through the vendor, ask for the safeguards in writing and for daily or weekly reporting.

Does outsourcing medical billing replace my bookkeeper?

No. Billing handles claims and patient accounts, while bookkeeping records deposits, fees, and receivables and produces financial statements. A bookkeeper also checks that the billing company's reports agree with the bank and the ledger, which is the control that catches missing or misapplied payments.
