In addition to confirming the previously identified asthma gene located on chromosome 17, researchers found another gene located on chromosome 1q31 was associated with an increased risk of childhood asthma in both children of European and African ancestry.
Coding asthma with ICD-9 codes has been based on extrinsic or intrinsic asthma. Extrinsic asthma is also known as allergic asthma. This is familiar as seasonal allergies. Intrinsic asthma is known by two additional names: exercise induced asthma and chemical induced asthma. When ICD-10-CM is implemented, it will not be necessary to code for the difference between extrinsic or intrinsic asthma. Asthma is found in section J45 of ICD-10-CM, and it will require documentation of mild, medium, and severe asthma.
