The term cellulitis is commonly used to indicate a nonnecrotizing inflammation of the skin and subcutaneous tissues, a process usually related to acute infection that does not involve the fascia or muscles. Cellulitis is characterized by localized pain, swelling, tenderness, erythema, and warmth.
The regions on chromosomes 7 and 12 may coincide with the asthma and atopy loci on the same chromosomes. Polymorphism in the IL1 cluster on chromosome 2 has also been shown to influence the severity of the disease (95, 96).
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.
