Z7901 - Currently taking blood-thinning medications long-term

International Classification of Diseases

Last updated: 3/24/2026

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code indicates that you are currently taking anticoagulant medications (blood thinners) on a long-term basis. Anticoagulants are medications that help prevent blood clots from forming. This is not a diagnosis of a disease, but rather a documentation code that healthcare providers use to record that you are on this type of medication therapy. Common anticoagulants include warfarin, heparin, and newer medications like rivaroxaban or apixaban. This code helps ensure all your healthcare providers are aware of your anticoagulant therapy when making treatment decisions.

Additional Information

This is a status code, not a billable diagnosis code. It's used for documentation purposes to indicate ongoing anticoagulant therapy. No direct costs are associated with this code itself, as it represents medication status rather than a service or procedure.
