Initially, the process of payment posting always required a member of the billing team to manually enter every line of the paper remittance until Electronic Remittance Advice (ERA) became the norm. Now, after the advent of ERA, the same data is integrated directly into a practice management or revenue cycle management (RCM) system.
ERA in medical billing is a computerized format of an Explanation of Benefits (EOB) sent by insurance payers to providers after the processing and adjudication of a medical claim. This digitized document contains all the details of a processed claim, explaining exactly what amount was paid, what amount was adjusted, and what amount was denied.
Health Insurance Portability and Accountability Act (HIPAA) mandates that health plans support the ERA 835 in a standardized format whenever a provider requests electronic delivery rather than a mailed paper remit.
Knowing how ERA 835 truly works is just as important for any practice attempting to maintain an efficient revenue cycle. Therefore, you must learn about ERA in insurance billing, step by step, and improve your RCM.
Importance of ERA in Medical Billing
An ERA is a crucial document in medical billing. Its purpose is to bridge the gap between filing a claim and understanding its true status. Without an ERA, billing staff must manually enter payment amounts, adjustment codes, and denial reasons into their system one claim at a time while waiting for paper mail. This method was no longer scalable because errors in payment posting were a result of the manual labor.
Additionally, ERA directly contributes to denial management. The billing personnel may understand exactly why a claim was underpaid or denied because the document contains particular adjustment and remark codes rather than an ambiguous dollar amount.
How Does ERA Processing Work?
Here is a step-by-step explanation of how ERA in medical billing works:
- The healthcare provider begins by submitting a medical claim electronically to the insurance payer.
- The payer processes the claim by verifying documentation and details such as patient eligibility, medical necessity of the procedure, coverage benefits, and contracted reimbursement rates.
- Based on these details, the payer decides whether to pay the claim, pay a reduced amount, deny the claim, or request additional information.
- Once the claim is processed, the insurance payer creates an Electronic Remittance Advice and sends the payment.
- The ERA file is automatically imported into the provider’s medical billing software, avoiding manual posting.
How do ERA and 835 files relate?
ERA and 835 are closely related and can be used interchangeably. However, it’s important to comprehend the difference. The ERA is what a payer sends to clarify a claim determination. Under HIPAA, an ERA must adhere to the 835 technical format. Each ERA that a provider receives, whether from a commercial payer or Medicare, is sent as an 835 file organized in accordance with the ASC X12N standard.
ERA vs. EOB: What’s the Difference?
Despite the fact that ERA in medical billing and EOB serve similar purposes, they differ greatly from one another:
| ERA in Medical Billing | EOB in Medical Billing | |
|---|---|---|
| Format | It contains all details included in an EOB, but in a digital format that works with the billing program. | This document details the claim, including payments, denials, and patient accountability. |
| Receiver | This document is sent to the healthcare provider. | This paper document is sent to both patients and healthcare providers. |
| Automation | The ERA is built for software integration to reduce administrative work significantly. | Information is manually input into the healthcare provider’s system. |
| Speed | This method is completely automated, and practice management software integration has proven to be much quicker. | This is a slow process because the manual paperwork and data entry involved in this process make it time-consuming. |
ERA Implementation Challenges for Providers
Healthcare providers face various challenges in implementing ERA billing in their practices. Some of them are discussed below.
Software Compatibility
Not every healthcare practice is in a position to implement ERA 835 in its medical billing system. The practice must update older software to properly receive, interpret, and post ERA files. Before implementing ERA in their billing system, providers should make sure it is compatible.
Employee Training
Billing personnel must comprehend how ERA in insurance billing operates and be able to decipher denial information, adjustment codes, and payment data. Employees may find it difficult to handle errors that cannot be posted automatically or to settle payment problems if they are not properly trained.
Maintenance Responsibilities and Updates
Software systems, payer requirements, and medical billing laws change over time. Providers must maintain payer enrollments, update their billing software, and check system performance to ensure correct Electronic Remittance Advice processing.
Benefits of Using Electronic Remittance Advice (ERA)
ERA billing can benefit your practice in the following ways:
- The main advantage of ERA in medical billing is auto-payment posting. Billing software imports the ERA file and automatically posts payments, adjustments, and patient responsibility amounts.
- This reduces the burden of manual labor.
- It also accelerates the revenue cycle and saves valuable time.
- Healthcare providers can monitor outstanding balances earlier and collect patient payments without delays.
- It promotes a stronger revenue cycle and enhances cash flow.
Final Thoughts
Healthcare providers can increase billing accuracy, reduce administrative effort, and expedite payment posting with Electronic Remittance Advice (ERA).
ERA in medical billing is essential to ensure quicker payment collection, improve cash flow, enable easier reconciliation, and optimize revenue cycle management. Healthcare organizations can improve staff and patient experiences while reducing errors, saving time, and streamlining financial workflow by switching to ERAs.
Working with a reputable medical billing and coding services provider ensures that your ERA processing, payment posting, denial management, and payment reconciliation are handled effectively, freeing your practice staff to concentrate on providing outstanding patient care while optimizing profits.
