ICD-10-CM (Clinical Modification) is the official system of assigning codes to diagnoses in the United States. It's used by healthcare providers, billers, and payers to ensure accurate documentation and reimbursement.
ICD-10 codes consist of 3-7 characters. The first character is always a letter, followed by digits. Characters 4-7 provide additional specificity about the diagnosis, including laterality, severity, and encounter type.
ICD-10 codes are required for all healthcare claims submitted to insurance payers. Accurate coding ensures proper reimbursement and helps track disease patterns for public health research.
CMS releases annual updates to ICD-10-CM codes every October 1st. These updates include new codes, revised descriptions, and deleted codes to reflect advances in medical knowledge.
