D87

D87 is an alphanumeric designation that appears in several standardized systems to label a category, item, or concept. There is no single universal meaning for D87; its interpretation depends on the domain and the governing code set.

In medical coding, alphanumeric codes are used to represent diagnoses and conditions. If D87 appears within a medical coding context, it typically functions as part of a hierarchical code; in ICD-10-CM, codes related to immune system disorders use the D80–D89 range, with D87 indicating immune-related conditions falling outside more specifically defined terms. The precise diagnosis is determined by additional digits and the accompanying documentation. Because coding schemes are updated periodically, clinicians and coders must consult current code books.

In data labeling and cataloging, D87 may serve as an identifier for a particular class or item. For example, product catalogs, bibliographic systems, and inventory databases assign such codes to organize items efficiently and to enable search and retrieval. The exact meaning is defined by the schema in use and is not comparable across systems.

When encountering D87, the recommended approach is to locate the system's official code table or legend and interpret the code within its proper context, checking any modifiers, suffixes, or related codes.
