Instructional Notations

Code First Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.

erythematous condition causing exfoliation, such as:
Ritter's disease L00
Staphylococcal scalded skin syndrome L00
Stevens-Johnson syndrome L51.1
Stevens-Johnson syndrome-toxic epidermal necrolysis
overlap syndrome L51.3
Toxic epidermal necrolysis L51.2
