By the end of this module, you will be able to:
Understanding human anatomy is foundational to medical coding. Accurate code assignment requires knowledge of:
Without a solid grasp of anatomy, medical coders may misinterpret documentation, leading to incorrect code assignment, claim denials, and potential compliance issues.
Medical terminology follows a logical structure that, once understood, makes learning new terms much easier. Most medical terms consist of:
A word part added to the beginning of a term that modifies its meaning (e.g., hyper-tension = high blood pressure).
The core of the word that carries the essential meaning (e.g., cardi-o- = relating to the heart).
A word part added to the end that modifies the meaning (e.g., bronch-itis = inflammation of the bronchi).
Recognizing these common prefixes will help you interpret medical documentation:
These suffixes frequently appear in medical documentation:
Understanding the major body systems is crucial for accurate medical coding. Here’s an overview of key systems:
Primary organs: Heart, blood vessels, blood
Key functions: Pumping blood to deliver oxygen and nutrients, removing waste
Common conditions: Hypertension, myocardial infarction, atherosclerosis, arrhythmias
Primary organs: Lungs, trachea, bronchi, alveoli
Key functions: Gaseous exchange, bringing oxygen into the body, removing carbon dioxide
Common conditions: Pneumonia, COPD, asthma, bronchitis
Primary organs: Mouth, esophagus, stomach, small and large intestines, liver, pancreas, gallbladder
Key functions: Breaking down food, absorbing nutrients, eliminating waste
Common conditions: GERD, ulcers, Crohn’s disease, gallstones, hepatitis
Primary organs: Kidneys, ureters, bladder, urethra
Key functions: Filtering blood, regulating water balance, eliminating waste through urine
Common conditions: UTI, kidney stones, renal failure, cystitis
Primary organs: Brain, spinal cord, nerves
Key functions: Processing information, controlling body functions and movement
Common conditions: Stroke, seizures, multiple sclerosis, Parkinson’s disease
Primary organs: Bones, muscles, joints, tendons, ligaments
Key functions: Movement, support, protection of internal organs
Common conditions: Fractures, osteoarthritis, osteoporosis, tendonitis
Medical documentation is filled with abbreviations. Understanding these is crucial for accurate code assignment:

| CVA | Cerebrovascular Accident (Stroke) |
| DM | Diabetes Mellitus |
| HTN | Hypertension |
| MI | Myocardial Infarction (Heart Attack) |
| CABG | Coronary Artery Bypass Graft |
| EGD | Esophagogastroduodenoscopy |
| I&D | Incision and Drainage |
| ORIF | Open Reduction Internal Fixation |
| PCI | Percutaneous Coronary Intervention |
| THA | Total Hip Arthroplasty |
| TKA | Total Knee Arthroplasty |
| BID | Twice a day |
| c/o | Complains of |
| Dx | Diagnosis |
| H/O | History of |
| NPO | Nothing by mouth |
| PRN | As needed |
| Tx | Treatment |
Understanding anatomy is essential for accurate code selection. Here’s how anatomical knowledge impacts medical coding:
Many ICD-10-CM codes require specific anatomical knowledge to select the correct code. For example, coding for fractures requires understanding of:
CPT and ICD-10-PCS procedure codes depend on knowledge of anatomical approaches. For example, to code correctly for gallbladder removal, you need to know the difference between:
Understanding how body systems interact helps identify related conditions that should be coded. For instance, recognizing that:
Anatomical knowledge helps coders interpret documentation accurately by:
When coding complex cases, it can be helpful to visualize the anatomy involved. Many coders keep anatomical charts or references nearby or use digital anatomical tools to ensure accuracy.
Medical coders should utilize these valuable resources to enhance their anatomical knowledge:
