Behind every successful medical practice is a highly accurate billing system. But before an insurance company pays you a single dollar, there is one critical step that dictates your entire cash flow: Charge Posting. If you get this wrong, your practice bleeds revenue. Here is everything you need to know about the most important phase of medical billing.
The Definition: What Is Charge Entry?
Charge posting (or charge entry) is the process of translating a patient’s medical encounter into billable data. It involves entering the exact services provided (CPT codes), the patient’s diagnosis (ICD-10 codes), and the corresponding financial fees into your Practice Management System (PMS) so a claim can be generated and sent to the payer.
The True Cost of Charge Entry Errors
Manual charge entry errors directly lead to massive revenue leakage. Here are the most common financial impacts affecting modern practices:
Nearly half of all claim denials originate from front-end charge capture errors.
Practices lose up to 3% of their net revenue solely due to “missed charges.”
Incorrect coding at the charge entry level adds two weeks to your payment cycle.
Without proper scrubbing, clean claim rates plummet from an ideal 95% down to 75%.
The 5 Stages of the Charge Posting Process
To fully understand revenue cycle management (RCM), you have to break down how a clinical note transforms into cash. This process requires absolute precision from your medical billing team.
Reviewing the Encounter Form (Superbill)
The process begins as soon as the provider completes the patient encounter and signs off on the clinical notes. The medical biller retrieves the superbill—either digital or paper—which contains the patient’s demographics, insurance details, and the provider’s preliminary procedural notes.
Verifying CPT and ICD-10 Codes
The biller carefully verifies the CPT codes and ICD-10 (diagnosis) codes. If a provider bills for a high-level established patient visit (e.g., CPT 99214), the ICD-10 codes must reflect a medical condition complex enough to justify that specific charge.
Applying Proper Modifiers
Modifiers are two-character codes appended to a CPT code to provide extra information to the insurance payer. For example, if a provider performs a procedure on both the left and right knee, a specific modifier must be used. Missing modifiers will result in automatic denials or bundled payment reductions.

Aligning the Fee Schedule
Once the codes are verified, the appropriate fees must be attached. This involves selecting the correct fee from your master fee schedule before the claim is generated. Accurate pricing ensures you are neither under-billing (leaving money on the table) nor over-billing (causing patient friction).
Claim Scrubbing and Submission
Finally, the charge is sent through a “scrubber”—software that checks the claim against specific insurance rules for errors. If it passes, it is converted into a CMS-1500 form (or electronic 837P format) and transmitted to the clearinghouse. Delays here directly result in the need to apply the 7 tips for quick AR recovery just to save your aging claims.
Why Practices Outsource Charge Posting
For small practices, forcing front-desk staff to handle patient flow and accurate charge posting is a recipe for disaster. The margin for error is simply too high. By utilizing professional charge entry services, practices experience:
- Reduced Denial Rates: Certified coders rarely make the simple bundling or modifier errors that trigger rejections.
- Faster Turnaround: Professional medical billing services for small practices guarantee charges are entered within 24 hours of the visit.
- Maximized Revenue: Expert billers know how to capture every single billable component of a visit, recovering the 1-3% of revenue that is typically lost to “missed charges.”
Frequently Asked Questions
What is the difference between charge entry and payment posting?
Charge entry (or charge posting) is the front-end process of entering billable codes into the system after a patient visit. Payment posting is the back-end process of recording the money received from the insurance company or patient against those initial charges.
How long should charge posting take?
Best practices dictate that charge entry should be completed within 24 to 48 hours of the patient encounter. If charges take a week to be posted, your entire payment cycle is delayed, leading directly to the need for AR recovery services.
Why are modifiers important in charge posting?
Modifiers provide insurance payers with additional context about a procedure (e.g., a bilateral procedure or multiple procedures in one visit). Missing or incorrect modifiers are a leading cause of claim denials and underpayments.
