Bullous disorders in diseases classified elsewhere (L14)

ICD-10 code L14 is used to classify bullous disorders that occur as part of other diseases rather than as primary skin conditions. This code helps specifically identify blistering skin issues that arise secondary to different underlying illnesses.

The term bullous disorders refers to conditions characterized by large, fluid-filled blisters on the skin. When these blisters develop due to systemic or other specified diseases rather than solely skin problems, the ICD-10 code for bullous disorders in diseases classified elsewhere (L14) is appropriate. This distinguishes such inflammatory skin conditions from primary blistering diseases, ensuring accurate medical coding and documentation for these complex cases. Using L14 helps healthcare professionals link blistering symptoms to an underlying disease context, facilitating better diagnosis, treatment planning, and data tracking.

Instructional Notations

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.
