2020 ICD-10-CM Diseases and Injuries - Index "H"

The ICD-10-CM Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). To find the ICD-10 code for a specific condition browse this alphabetical index of clinical terms and conditions. Keep in mind that a condition may not appear under the exact same phrasing so make sure to use synonyms. Once you have identified the condition the ICD-10 code(s) should be listed next to that condition.
