Decoding Medical Coding: Simplifying Complex Terms

Medical terminology can seem like an overwhelming mountain of complex words and concepts to climb. However, having a basic grasp of some of the fundamental elements of medical coding can go a long way in helping decipher even lengthy, multi-faceted terms. Breaking down the component parts and tracing medical language back to its roots in Latin and Greek is key. With some dedicated study and memorization of prefixes, suffixes, and word roots, what once seemed an unintelligible alphabet soup can start to make logical sense.

The Purpose Behind Medical Coding

First, it’s important to understand the raison d’être behind medical coding overall. In a nutshell, medical coding provides a standardized system to classify diseases, symptoms, diagnoses, procedures, and medical services. According to the folk over at, this coding system helps in billing and medical billing codes for insurance reimbursement purposes. The complex coding terminology allows detailed specificity in documentation, analytics, and health data reporting. Some of the main medical coding classification systems include:

  • ICD codes: International Statistical Classification of Diseases codes classify diagnoses.
  • CPT codes: Current Procedural Terminology codes provide terminology for procedures and services. 
  • HCPCS codes: Healthcare Common Procedure Coding System codes also cover procedures, services, products, and supplies.

Breaking Down the Components

Medical terminology can look like an endless string of convoluted phrases but recognizing a few basic building blocks makes decoding easier. Many terms contain multiple word parts layered together to convey intricate detail. Breaking a term down into its composite parts and analyzing the meaning of each component piece by piece reduces the intimidation factor substantially.

Look for these types of elements nested within medical terminology:

  • Prefixes – added to the beginning of a term to modify the root’s meaning. Examples include per-, hyper-, anti-. 
  • Root words – the primary part of a term containing its essential meaning. Examples are cardia (heart) or ology (study of).  
  • Suffixes – added to the end of a term to transform it into a certain word type like a diagnosis, procedure, anatomy or physiology. Examples include -itis, -otomy, -emia.
  • Connecting vowels – connect word roots and parts smoothly together in proper pronounceable forms. The vowel “o” is commonly used.
  • Parts denoting anatomy – descriptive directions pinpointing locations on the body like anterior, proximal, dorsal.

Memorizing the Building Blocks

Certainly, memorizing the many prefixes, suffixes and word roots that comprise the bulk of medical terminology takes dedication and repetition. But repeated exposure and use of these standardized elements imprints them more permanently. And consistent study, even just targeting a handful of word parts at a time, accumulates the basic tools to assemble complex phrases. The good news is that you don’t have to memorize the codes – you can find them on online databases and in medical coding books. 

Practical Application for Clarity 

The purpose behind acquainting ourselves with medical coding and terminology goes beyond intellectual curiosity. Precise medical language and documentation ensures continuity of care amongst various providers and accurate record keeping. Patients can better advocate for their own care when conversant in basic vocabulary relating to their health status.

Terminology proficiency assists hospital coders in correctly assigning diagnosis, procedure, and service codes for reporting and billing. Billing and insurance claims processing depends on properly sequenced medical coding matching providers’ documentation.  


At first glance, medical vocabulary can feel intimidating and impersonal. Yet these meticulously crafted terms evolved out of necessity – to articulate the body’s conditions with nuance and precision. Familiarity with word building techniques makes multisyllabic phrases less daunting. Prefixes, roots, and suffixes function like distinct keys, unlocking explicit medical expressions. Bit by bit, the language opens itself up to those willing to dedicate themselves to its deciphering.
