Chapter 12: Diseases of the Skin and Subcutaneous Tissue
ICD-10 to ICD-11 crosswalk mappings for codes L00-L99
392 ICD-10 codes in this chapter have ICD-11 crosswalk mappings from the WHO.
Covers dermatitis, eczema, psoriasis, cellulitis, acne, pressure ulcers, urticaria, and skin infections. Cellulitis (L03) is a common reason for emergency department visits and hospital admissions, while dermatitis codes are frequently used in dermatology and primary care.
