For the structured representation of medical record data a formalism is in demand that both is expressive and supports classification. Common classification and coding systems in medicine make a compromise on these aspects. This paper proposes a model for compositional classification that is based on restricted conceptual graphs. Basic elements are primitive concepts that can be composed to composite concepts via roles. In contrast to the full expressiveness of the conceptual graph formalism the model restricts composite concepts to connected tree-like graphs without quantification, or specification of referents. The model emphasizes a clear distinction between subsumption and part-of relations. Definitions are given that solely base on the structure of composite concepts, and explicit subsumption and part-of relations between primitive concepts. The composition of concepts is constrained by the domain and the range of a role, and by global and local role restrictions. A global restriction limits the range of a role for a primitive concept, a local restriction limits the range of a role for a primitive concept in the context of a composite concept. The model is applied to the AO classification of fractures of long bones. This outlines how a conventional combinatorial coding system can be represented in terms of a compositional classification system.
