R13

R13 is an alphanumeric designation used across multiple domains, so it does not have a single universal meaning. Its interpretation depends on the field in which it appears.

In medicine, R13 is the ICD-10-CM diagnosis code for dysphagia, or difficulty swallowing. This code is used in medical records and billing to indicate swallowing difficulties and may be subdivided in more specific contexts within the broader dysphagia category.

In fashion, R13 refers to a contemporary American streetwear label known for its distressed denim and rock-inspired designs. The brand has gained recognition for its bold, casual-yet-fashion-forward pieces and is often marketed simply as R13.

In transportation networks, R13 can denote a regional road designation in countries that use the R-prefix for regional routes. In such systems, the letter R signals a regional road, while the number 13 identifies a specific route within that network. The exact route and characteristics vary by country or region.

In addition, R13 may appear as a model or part number in various products and equipment, where it serves as an internal identifier rather than a description of function.

Because the meaning of R13 is highly context-dependent, consulting domain-specific sources is essential to determine the precise definition in a given instance.
