Master the art and science of inpatient diagnosis-related group coding with the most comprehensive curriculum designed for aspiring medical coders. From foundational DRG concepts to live chart preparation and interview readiness — your career in health information management starts here.
IPDRG Basics — Building Your Foundation
Every successful inpatient coder begins with a rock-solid understanding of the DRG system. This opening module walks you through the essential building blocks that drive inpatient reimbursement and data quality across U.S. hospitals. You will learn how each concept connects to accurate coding and proper claim submission.
POA Indicator
The Present on Admission indicator identifies whether a condition existed at the time of the patient's admission. Understanding POA is critical because it directly affects DRG assignment, reimbursement, and quality reporting metrics used by CMS.
CC / MCC / HAC
Complication or Comorbidity (CC), Major Complication or Comorbidity (MCC), and Hospital-Acquired Conditions (HAC) classifications determine severity adjustments. These designations can shift a case into a higher-paying DRG or trigger payment penalties.
DRG Types
Learn the distinctions between MS-DRG (Medicare Severity), APR-DRG (All Patient Refined), and IR-DRG (International Refined). Each system serves different payer populations and uses unique logic for grouping diagnoses and procedures.
Discharge Disposition
The discharge disposition code describes where the patient goes after the hospital stay — home, skilled nursing, rehabilitation, or another facility. Accurate reporting ensures compliance and affects readmission tracking under CMS programs.
IPDRG Fundamental Topics — Coding Diagnoses & Procedures
Once you understand DRG basics, it is time to master the rules that govern how principal and secondary diagnoses and procedures are selected and sequenced. These UHDDS-based guidelines form the backbone of every inpatient coding decision you will make throughout your career.
Diagnosis Coding
Principal Diagnosis — UHDDS Guidelines
The principal diagnosis is defined as the condition established after study to be chiefly responsible for occasioning the admission. You will learn how to evaluate documentation, resolve conflicting information, and apply official sequencing rules correctly.
Secondary Diagnosis — Reporting Additional Diagnoses
Secondary diagnoses capture every condition that affects patient care, treatment, or length of stay. Proper reporting of these codes drives CC/MCC capture and ensures the DRG reflects true resource consumption.
Procedure Coding
Principal Procedure — UHDDS Guidelines
The principal procedure is the one performed for definitive treatment rather than diagnostic or exploratory purposes, or the procedure most closely related to the principal diagnosis. Accurate selection is essential for surgical DRG assignment.
Secondary Procedures
All additional procedures that meet reporting criteria must be captured. These may include ancillary surgeries, device insertions, or therapeutic interventions that influence the DRG grouper outcome and overall reimbursement.
Following this systematic workflow ensures consistent, compliant coding that aligns with both CMS requirements and payer expectations.
ICD-10-CM Official Guidelines — Conventions & General Rules
The ICD-10-CM Official Guidelines for Coding and Reporting are the authoritative reference every inpatient coder must know. This extensive module covers Section I in its entirety, starting with how to navigate coding software and websites to locate the correct codes efficiently.
Part 1 — Conventions (A)
Covers conventions 1 through 19 including instructional notes, punctuation, abbreviations, "Code first," "Use additional code," "Excludes1/Excludes2," and cross-references that guide proper code selection.
Part 2 — General Guidelines (B)
Addresses guidelines 1 through 20, covering laterality, documentation requirements, signs and symptoms coding, combination codes, sequelae, and the critical rules for reporting conditions that are integral versus incidental to the visit.
Chapter-Specific Guidelines — Disease Categories
The bulk of the ICD-10-CM training dives deep into chapter-specific rules. Each ICD-10-CM chapter has unique conventions, sequencing priorities, and coding nuances that affect DRG assignment. Below is the complete scope covered across eight dedicated sessions.
ICD-10-PCS Guidelines — Mastering Procedural Coding
The ICD-10 Procedure Coding System (PCS) is a sophisticated, multi-axial system used exclusively for inpatient procedure reporting. Unlike ICD-10-CM, PCS codes are built character by character, with each of the seven positions carrying specific meaning. This module provides a thorough exploration of PCS structure, conventions, and all 17 sections.

7 characters, 17 sections, 7 approaches, devices, and qualifiers
Medical & Surgical Root Operations
All 31 root operations (1–31) with definitions and examples
Ancillary Sections

Focus: Basic Inpatient Procedures
Before tackling complex surgical cases, every coder must be familiar with the routine procedures performed daily in inpatient settings. These foundational procedures form the majority of coded encounters and require precise PCS code construction. This module covers diagnostic, therapeutic, vascular access, renal, and medication-related procedures.
Diagnostic Procedures
- Blood draw & ABG sampling
- X-ray, CT, MRI, Ultrasound
- ECG/EKG & Echocardiography
- Telemetry monitoring
Bedside Therapeutic Procedures
- Nebulization & oxygen therapy
- NG tube insertion & feeding tube management
- Wound dressing change & debridement
- VAC dressing application
Vascular Access Procedures
- Peripheral & central venous line insertion
- PICC line & Port-a-cath access
- Arterial line insertion
Fluids, Medications & Transfusions
IV fluid administration, medication delivery (IV/IM/SC), blood transfusions, and electrolyte replacement protocols are among the most frequently coded inpatient services.
Renal & Urinary Procedures
Foley catheter insertion, intermittent catheterization, bladder irrigation, and urinary stent care require careful PCS code selection based on approach and device used.
Emergency & Critical Care
Endotracheal intubation, cardioversion/defibrillation, CPR, chest tube management, and pericardiocentesis — high-acuity procedures that significantly impact DRG weight.
Minor Surgical Procedures
Abscess I&D, lumbar puncture, paracentesis, thoracentesis, and joint aspiration — commonly encountered in both medical and surgical DRG pathways.
Focus: Major Inpatient Surgical Procedures
Major surgical procedures carry the highest DRG weights and demand precise coding of root operations, body parts, approaches, and devices. This module covers the most commonly encountered major inpatient surgeries organized by specialty. Mastering these procedure categories is essential for accurate reimbursement and quality reporting.
Cardiothoracic
CABG, valve repair/replacement, aortic aneurysm repair, pacemaker/ICD implantation, thoracotomy, lobectomy, PTCA
Abdominal Surgery
Appendectomy, cholecystectomy, colectomy, gastrectomy, pancreatectomy, splenectomy, bowel resection, hernia repair
Neurosurgery
Craniotomy, brain tumor resection, aneurysm clipping/coiling, spinal fusion, laminectomy, VP shunt placement
Orthopedic
TKR, THR, ORIF, arthroscopy, spinal instrumentation, major amputation
OB/GYN Surgeries
Cesarean delivery, hysterectomy (vaginal/abdominal/laparoscopic), oophorectomy/salpingectomy, myomectomy, and pelvic prolapse repair are common inpatient encounters with specific PCS coding requirements for approach and extent.
Urological Procedures
TURP, nephrectomy, cystectomy, ureteric reimplantation, and lithotripsy with stent placement require careful root operation selection — distinguishing between excision, resection, and destruction.
Vascular & GI/Hepatobiliary
Carotid endarterectomy, AV fistula creation, peripheral bypass, thrombectomy, ERCP with stenting, liver resection, and complex hemorrhoidectomy round out the major procedure categories.
ENT, Head/Neck & Reconstructive
Thyroidectomy, radical neck dissection, major sinus surgery, skin grafting, flap reconstruction, burn excision, and post-mastectomy breast reconstruction complete the surgical spectrum.
