Primary Immunodeficiency is a condition characterized by a weakened immune system, making individuals more susceptible to infections. The ICD-10 code for Primary Immunodeficiency is D80.9. In contrast, the ICD-9 code for this condition is 279.00. These codes are used for medical billing and coding purposes to accurately identify and classify the condition for healthcare providers.
Primary immunodeficiency (PID) refers to a group of inherited disorders that affect the immune system, leading to increased susceptibility to infections. The International Classification of Diseases, Tenth Revision (ICD-10) provides codes to classify and document various medical conditions. The specific ICD-10 code for primary immunodeficiency depends on the specific type of PID.
For instance, one common type of PID is common variable immunodeficiency (CVID). The ICD-10 code for CVID is D83.0. This code falls under the "Other immunodeficiencies with predominantly antibody defects" category. Other types of primary immunodeficiencies have their own unique ICD-10 codes, such as severe combined immunodeficiency (D81.0), Wiskott-Aldrich syndrome (D82.0), and hyper IgM syndrome (D82.4), among others. These codes allow healthcare professionals to accurately diagnose and code patients with primary immunodeficiency.
Prior to the implementation of ICD-10, the ninth revision (ICD-9) was used. The ICD-9 code for primary immunodeficiency was 279.06. This code fell under the "Other specified disorders involving the immune mechanism" category.
It is important to note that the ICD-10 and ICD-9 codes are used for medical billing, research, and statistical purposes. They help healthcare providers and organizations track and analyze data related to specific conditions, including primary immunodeficiency. These codes ensure standardized documentation and facilitate communication between healthcare professionals. However, it is always recommended to consult a healthcare professional or medical coder for accurate and up-to-date coding information, as codes may be subject to updates and revisions.
