Understanding the structure of ICD-10 Codes

What exactly is ICD 10 code?

A well-known system that provides standardization and classification for clinical diagnosis, symptoms, and comorbidities in the healthcare sector is the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM). This system provides the information required for classifying morbidity and diagnostic specificity. The Centers for Disease Control and Prevention and the World Health Organization have published this useful clinical data recording system (CDC). Healthcare professionals use ICD-10-CM codes to store information on medical conditions or diagnoses to retrieve patients' medical information quickly.

Understanding the Structure of ICD-10-CM Code

The ICD-10-CM code is structured with three to five characters, with the first character being alphabetical and the second and third being numeric. Characters four to seven may consist of a combination of alpha and numeric characters. The first three letters of the code identify the injury. At the same time, the fourth through sixth characters provide a more detailed classification of the cause, anatomical site, and severity of the disease. A seventh character is used as an extension digit to classify the encounter as original, subsequent, or late-effect treatment. The ICD-10-CM also includes the placeholder character "X" for future code extensions. For example, the code P35.2 is used for Congenital herpes viral [herpes simplex] infection, and P35.4 is used for Congenital Zika virus disease.
