EHR and EMR are often used interchangeably, but they describe different things — and understanding the difference matters for anyone working in billing, since these systems are where charge capture and coding usually begin.
EMR vs. EHR: What’s the Difference?
An EMR (Electronic Medical Record) is a digital version of a single practice’s paper charts — it holds the diagnosis and treatment history for patients within that one office and generally doesn’t travel with the patient if they switch providers.
An EHR (Electronic Health Record) is broader by design: it’s built to be shared across providers, specialists, labs, and pharmacies, giving a more complete picture of a patient’s health over time. Most modern systems marketed today are technically EHRs, even though the term “EMR” is still used casually.
How EHR/EMR Systems Connect to Billing
- Charge capture — providers document the visit and select or confirm diagnosis/procedure codes directly in the system.
- Claim scrubbing — many systems flag missing modifiers, mismatched code pairs, or incomplete documentation before a claim goes out.
- Clearinghouse integration — most EHR/practice management platforms connect directly to a clearinghouse to submit claims electronically.
- ERA posting — electronic remittance advice can often post back into the system automatically, reconciling payments against charges.
Interoperability: HL7 and FHIR
Interoperability — the ability for different systems to exchange data — relies on data standards. HL7 (Health Level Seven) is the long-standing messaging standard for exchanging clinical data between systems. FHIR (Fast Healthcare Interoperability Resources) is the modern, API-based standard that’s increasingly required for patient data access and system integrations.
Common EHR/EMR Platforms
The system a practice uses shapes how billing tasks actually get done day to day. Below are 20 widely used EHR/EMR and practice management platforms, spanning hospital systems, ambulatory practices, and specialty settings, with links to each vendor’s official site for further learning.
- Epic — the dominant EHR in large hospital systems and academic medical centers; known for its MyChart patient portal and Hyperspace billing tools.
- Oracle Health (Cerner) — widely used across hospitals and health systems, particularly for inpatient and enterprise revenue cycle management.
- athenahealth — cloud-based EHR and practice management popular with ambulatory practices, with built-in claim-scrubbing and RCM services.
- eClinicalWorks — a common choice for small-to-mid-size practices, offering integrated billing and telehealth.
- NextGen Healthcare — ambulatory EHR and practice management platform used across many specialty groups.
- Kareo / Tebra — cloud-based platform aimed at independent and small practices, with billing, scheduling, and patient engagement tools.
- DrChrono — an iPad-friendly EHR and medical billing platform popular with smaller practices.
- Allscripts (Veradigm) — long-standing EHR vendor serving hospitals and ambulatory practices, with integrated revenue cycle tools.
- Greenway Health — ambulatory EHR/PM suite (Intergy) used in many specialty and primary care practices.
- Practice Fusion — a cloud-based EHR marketed to independent practices, with a simplified billing workflow.
- AdvancedMD — practice management and EHR platform with a strong medical billing/RCM module used by billing companies.
- CareCloud — cloud-based EHR and RCM platform aimed at small and mid-size practices.
- MEDITECH — a major inpatient/hospital EHR platform, especially common in community hospitals.
- CPSI (Evident) — EHR and financial systems focused on rural and community hospitals.
- Modernizing Medicine (ModMed) — specialty-specific EHR (dermatology, orthopedics, ophthalmology, gastroenterology, and more) with specialty-tailored coding tools.
- Office Ally — a widely used clearinghouse and free/low-cost practice management platform, popular with small practices and billing services.
- SimplePractice — EHR and practice management built specifically for behavioral health, therapy, and wellness practices.
- TherapyNotes — EHR and billing platform designed for mental and behavioral health providers.
- WebPT — EHR and billing platform built for physical, occupational, and speech therapy practices.
- PointClickCare — EHR platform focused on long-term and post-acute care (skilled nursing, senior living).
Each has its own billing module, claim-scrubbing rules, and reporting quirks — coders and billers moving between systems should expect a learning curve even when the underlying coding rules don’t change. Vendor sites above typically include free product tours, demo videos, or resource centers useful for self-guided learning.

Practice on a Training EHR
The best way to learn how an EHR connects to billing is to use one. Fernwell Training EHR is a practice EHR for students and new billers: you schedule and register fictional patients, verify eligibility, code visits, submit claims to the built-in Claimstead training clearinghouse, post ERAs and work denials. Every patient is fictional and every payer response is simulated. (Fernwell is made by the team behind MedicalBillingInfo.com.)
