Other diseases of capillaries

This code represents various uncommon or unspecified conditions affecting the capillaries, the smallest blood vessels in the body. It encompasses capillary disorders that are not specifically classified elsewhere in ICD-10-CM, such as certain forms of capillary fragility or other rare capillary dysfunctions.

Use this code when documentation indicates a capillary disorder that does not have a more specific ICD-10-CM code. This may include diagnoses like "capillary fragility, NOS," "capillary dysfunction, NOS," or other rare, non-inflammatory, non-hemorrhagic capillary conditions. Ensure the physician's notes clearly identify the condition as primarily affecting the capillaries and that no other, more specific code is applicable.

• Always review the medical record for more specific diagnoses of capillary disorders (e.g., hereditary hemorrhagic telangiectasia, purpura) before assigning this code.
• This code should be used as a last resort when no other specific capillary disease code is available.
• Consider sequencing this code after a more definitive underlying systemic disease if the capillary involvement is a manifestation of that primary condition.
