Download the essential ICD-10 code reference for 2026.
The 2026 ICD-10 Code Guide includes all newly added ICD-10 codes, revised code descriptions, and deleted codes applicable for the 2026 billing year to support accurate medical coding and reimbursement.
The 2026 ICD-10 code updates take effect on January 1, 2026, and must be used for services rendered on or after the effective date to remain compliant with payer requirements.
Using updated ICD-10 codes ensures correct claim submission, prevents denials caused by outdated codes, and helps practices receive accurate and timely reimbursements.
Claims submitted with deleted ICD-10 codes are typically rejected or denied, leading to payment delays and potential compliance risks.
The guide is intended for healthcare providers, medical billers, certified coders, and revenue cycle teams responsible for ICD-10 coding accuracy.
