Illustrated Anatomical and Procedural Review – Explanation
Why this page is important
- CPC exam tests medical terminology meaning
- If you know prefix + root + suffix, you can guess answers even if the word is new
- This page is a quick reference for coding accuracy
1. Prefixes, Suffixes, and Roots (Basics)
Prefix
- Comes at the beginning of a word
- Changes the meaning
Suffix
- Comes at the end of a word
- Often tells condition, disease, procedure
👉 Example:
Appendicitis
- appendic = appendix
- -itis = inflammation
2. Common Prefixes (Conditions)
| Prefix | Meaning | Example | Meaning of Example |
|---|---|---|---|
| ambi- | both | ambidextrous | both hands |
| aniso- | unequal | anisocoria | unequal pupils |
| dys- | bad / painful | dysphoria | discomfort |
| eu- | good / normal | euthanasia | good death |
| hetero- | different | heterogeneous | different types |
| homo- | same | homogeneous | same type |
| hyper- | excessive / above | hypergastric | above stomach |
| hypo- | below / deficient | hypogastric | below stomach |
| iso- | equal | isotonic | equal tension |
| mal- | bad / poor | malaise | discomfort |
| megalo- | large | megalocardia | enlarged heart |
📌 CPC Tip:
Hyper = high
Hypo = low
👉 Very common MCQ trick!
3. Suffixes (Conditions)
| Suffix | Meaning | Example |
|---|---|---|
| -algia | pain | neuralgia |
| -asthenia | weakness | myasthenia |
| -emia | blood condition | anemia |
| -iasis | condition | amebiasis |
| -itis | inflammation | appendicitis |
| -lysis | breakdown | hemolysis |
| -lytic | destroying | hemolytic |
| -oid | like | lipoid |
| -oma | tumor | carcinoma |
| -opathy | disease | arthropathy |
| -rrhagia | bleeding | hemorrhage |
| -rrhea | discharge | amenorrhea |
| -osis | abnormal condition | tuberculosis |
| -paresis | weakness | hemiparesis |
| -plasia | growth | hyperplasia |
| -plegia | paralysis | paraplegia |
| -pnea | breathing | apnea |
📌 High-yield CPC suffixes:
-itis, -oma, -osis, -ectomy, -otomy
4. Number Prefixes
| Prefix | Meaning | Example |
|---|---|---|
| mono-, uni- | one | unilateral |
| bi- | two | bilateral |
| tri- | three | triad |
| quadr- | four | quadriplegia |
| hex-, sex- | six | hexose |
| diplo- | double | diplopia |
📌 Exam Trick:
Unilateral ≠ Bilateral
(one side vs both sides)
5. Surgical Procedure Suffixes (VERY IMPORTANT)
| Suffix | Meaning | Example |
|---|---|---|
| -centesis | puncture to remove fluid | amniocentesis |
| -ectomy | surgical removal | appendectomy |
| -ostomy | new opening | colostomy |
| -otomy | cutting into | tracheotomy |
| -orrhaphy | surgical repair | herniorrhaphy |
| -pexy | fixation | nephropexy |
| -plasty | repair | rhinoplasty |
| -tripsy | crushing | lithotripsy |
📌 Golden Rule for CPC:
- -ectomy = remove
- -otomy = cut
- -ostomy = opening
6. How CPC Uses This Page
- MCQs asking meaning of medical terms
- Procedure vs diagnosis identification
- Modifier logic (later chapters)
- ICD-10 & CPT understanding
