ICD-10 Code Database & Resources

What are ICD-10 Codes?

ICD-10 (International Classification of Diseases, 10th Revision) codes are alphanumeric codes used by healthcare providers, insurers, and public health agencies to classify and code diagnoses, symptoms, and procedures. These codes are essential for:

• Medical Billing: Submitting claims to insurance companies
• Clinical Documentation: Recording patient diagnoses accurately
• Health Statistics: Tracking disease prevalence and outcomes
• Quality Measurement: Monitoring healthcare quality metrics
• Research: Conducting epidemiological studies

• Related Codes: Similar or related diagnosis codes to consider

Searching for Codes

Use the search box above to find codes by:

• Code number (e.g., "I10", "E11.9")
• Disease name (e.g., "diabetes", "hypertension")
• Symptom or condition (e.g., "chest pain", "depression")
• Specialty or body system (e.g., "cardiology", "respiratory")

ICD-10 Coding Guidelines

Accurate ICD-10 coding requires following official coding guidelines:

• Code to the highest level of specificity: Use the most detailed code available
• Document clinical significance: Only code conditions that affect patient care
• Use combination codes when available: Single code for multiple conditions
• Sequence codes appropriately: Primary diagnosis first, then secondary
• Verify billable status: Ensure the code can be used for reimbursement

Code Structure

ICD-10-CM codes follow a specific structure:

• 1st character: Letter indicating the chapter (e.g., I = Circulatory)
• 2nd & 3rd characters: Numbers indicating the category
• 4th-7th characters: Additional specificity (etiology, severity, laterality)

Example: E11.65 = Type 2 diabetes (E11) with hyperglycemia (.65)
