AHA Coding Clinic® for ICD-10-CM and ICD-10-PCS - 2022 Issue 4; New/Revised ICD-10-CM Codes
Activated Phosphoinositide 3-Kinase Delta Syndrome [APDS]
A new code was created to identify activated phosphoinositide 3-kinase delta syndrome (D81.82).APDS (PI3K delta syndrome) is a rare primary immune regulatory disorder (PIRD) caused by genetic variants in either one of two identified genes known as PIK3CD or PIK3R1. It is a combined immunodeficiency and impairs the immune system such that individuals with this condition typically have low numbers of white blood cells, particularly certain types of B cells and T cells.APDS usually manifests during early childhood. The most common symptoms are frequent and severe infections of the ears, sinuses, herpes virus infections, neurodevelopment delay...
