ICD-10-CM Code For Methemoglobinemia: Group Overview
The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group D74 includes methemoglobinemia diagnoses, covering inherited enzyme deficiency-related forms and acquired oxidant-induced forms that increase methemoglobin levels and reduce oxygen delivery. These ICD-10-CM diagnosis codes are used to document clinical scenarios such as symptomatic hypoxia with confirmed elevated methemoglobin levels, exposure to oxidizing agents, or congenital cytochrome b5 reductase deficiency, capturing disease severity and treatment complexity. Accurate coding within the ICD-10-CM D74 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM D74: Methemoglobinemia Overview
The diagnoses in this group represent methemoglobinemia, a disorder involving elevated methemoglobin levels that impair oxygen delivery. These conditions affect the blood and oxygen-carrying capacity, often due to congenital enzyme defects or acquired oxidant exposure. Accurate coding matters for reimbursement because it captures clinical severity and guides appropriate claim processing.
