Frequently Asked Questions

What is ICD-10-CM?

ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) is the official system used in the United States to classify and code diagnoses and symptoms. It's required for medical billing, quality reporting, and public health surveillance.

How current is this data?

Our ICD-10 lookup uses the NLM Clinical Tables API, which is maintained by the National Library of Medicine and updated with each annual CMS release. This ensures you always have access to the most current codes.

Can I search by description?

Yes! You can search by ICD-10 code directly (e.g., "I10") or by natural language descriptions (e.g., "high blood pressure" or "hypertension"). The search will match both codes and descriptions.

What's the difference between ICD-10-CM and ICD-10-PCS?

ICD-10-CM is used for diagnosis coding (what the patient has), while ICD-10-PCS (Procedure Coding System) is used for inpatient procedure coding. This tool specifically covers ICD-10-CM diagnosis codes.
