For convenience, a list of common ICD-10-CM codes is provided below. The ordering clinician is responsible for selecting the appropriate diagnosis based on the patient’s signs and symptoms. Only diagnoses that are medically necessary may be submitted, and codes should match with those documented in the patient’s medical record. This list serves as a reference tool and is not intended to recommend a specific code for any patient encounter.
For a comprehensive list, please refer to the ICD-10-CM manual. For more information on using ICD-10 codes, please see this page provided by the AAPC What Is ICD-10?
