Disease of capillaries, unspecified

This code represents an unspecified pathological condition affecting the smallest blood vessels, the capillaries. It indicates a general or ill-defined disorder of the microvasculature without further specification of the exact nature or cause of the capillary disease.

Use this code when documentation indicates a capillary disease but lacks specific details regarding its type, etiology, or manifestation. This is typically a last resort when more specific codes for capillary disorders (e.g., capillaritis, capillary fragility) cannot be assigned due to insufficient clinical information.

• Avoid using this code if more specific documentation exists regarding the type of capillary disease (e.g., I78.0 for hereditary hemorrhagic telangiectasia).
• Query the provider for further specificity if "capillary disease" is noted without additional descriptive terms.
• This code is often used when a definitive diagnosis of a specific capillary disorder has not yet been established or is not documented.
