Master the Most Audited Inpatient Combination Code Matrix
Stop freezing when you see a complex cardiopulmonary chart. In under 60 minutes, learn how to sequence Hypertensive Heart and Chronic Kidney Disease combinations with senior-level accuracy and compliance reflexes.
Why Textbook Rules Fail You on the Inpatient Floor
In school, they teach you standard coding rules using clean, one-sentence multiple-choice questions. They tell you that category I13 represents hypertensive heart and chronic kidney disease, and you move on.
But when you're sitting in front of a real EMR chart, the provider doesn't write in clean definitions. They write pages of unstructured history, list comorbid conditions, and leave it to you to understand the UHDDS sequencing guidelines.
If you sequence the heart failure separately because the doctor didn't explicitly write "due to," you violate the presumption rule. If you apply the presumption to cardiomyopathy or acute kidney injury, you create a massive compliance risk. Facility auditors check this category first because it represents the highest volume of DRG weight shifts and compliance findings.
This mini-training skips the textbook fluff and gives you the exact clinical reflexes you need to audit, sequence, and code these complex scenarios with confidence.
The Auditor's Check
When coding Hypertensive Heart and CKD combinations, senior auditors watch for three common traps:
- Presumed Causation Bounds: The presumption applies only to CKD and chronic heart conditions. It does NOT apply to cardiomyopathy (I42.-) or acute kidney injury (N17.-).
- Sequencing Hierarchy: If the patient is admitted for acute heart failure or CKD, the combination code (I13.-) MUST be sequenced as the Principal Diagnosis.
- Additional Manifestations: You must always report the type of heart failure (I50.-) and the CKD stage (N18.-) as additional codes.
A 3-Step Practical Blueprint
This free training doesn't waste time on dry slides. You will work directly inside our interactive EMR system to master these 3 core modules:
The Presumed Relationship Rule
Learn exactly when the ICD-10-CM classification presumes a causal link between hypertension, heart failure, and chronic kidney disease, and identify the specific clinical diagnoses that are excluded from this presumption.
The Combination Matrix (I13)
Master the structure of category I13. Understand how to sequence combinations when multiple conditions exacerbate simultaneously, and how to assign secondary indicators (I50 and N18 stages) correctly.
Clinical Chart Simulator Practice
Apply your knowledge to a realistic multi-page inpatient EMR chart. Research history, check labs and physician notes, select your codes in the RCE Coding Workbench, and get instant grading with audit-level rationales.
We Don't Do Boring Quizzes
RCE is built on the belief that you cannot learn real-world facility coding by answering multiple-choice questions. You learn by doing the work.
Real Inpatient Chart Practice
Interact with multi-tabbed medical records featuring history and physicals, progress notes, labs, and specialist consultations.
Active Code Selection
Type and select actual ICD-10-CM codes. Learn how sequencing order alters the MS-DRG weight in real-time.
SME-Guided Rationales
Receive immediate, granular feedback on your sequencing mistakes, outlining exactly what guidelines apply and why.

Founder & Curriculum Director, RCEAs a professional medical coder and educator, I founded Reilly Coding Education to solve a specific gap: traditional certification prep teaches you rules, but fails to prepare you for the complex clinical realities of actual EMR charts.
This mini-training contains the exact drills I use to help coders develop their inpatient coding reflexes, helping you transition from rules-oriented theory to active clinical analysis.
Frequently Answered
Have questions about this free mini-training? Here is what other coders ask before enrolling.
Yes. This is a 100% free offering containing 3 interactive lessons from our curriculum. We offer this training so you can experience RCE's interactive EMR practice workbench firsthand before considering our advanced facility coding programs.
This course is designed for certified coders (CPC, CCS, etc.) who want hands-on inpatient coding practice, or outpatient/pro-fee coders looking to transition to inpatient facility roles. It assumes you already know basic medical terminology and coding lookup, and moves straight to advanced clinical application.
You have lifetime free access to these three interactive lessons. You can repeat the EMR chart simulations as many times as you like to practice your sequencing and get feedback.
Yes, all cases and rationales in this training are fully updated and compliant with the latest FY2026 ICD-10-CM Official Guidelines for Coding and Reporting.
