    ICD-10-CM Code For Other Disorders Of Veins: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group I87 includes nonthrombotic venous disorders such as chronic venous insufficiency, superficial phlebitis, and other specified disorders of veins affecting venous function and structure. These ICD-10-CM diagnosis codes are used to document clinical encounters involving venous obstruction, insufficiency, inflammation, or other specified venous pathology, capturing disease severity and anatomic involvement. Accurate coding within the ICD-10-CM I87 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    When to Use

    Use a code from this group when the clinical documentation specifies a nonthrombotic, nonvaricose disorder of veins such as chronic venous insufficiency, superficial phlebitis, or other specified venous conditions. Select the most specific code that reflects the anatomic site, laterality, and any associated complications when documented.

    Typical Clinical Scenarios

    • An older adult presents to the emergency department with acute swelling, pain, and a tense, darkened calf after recent prolonged immobility following hospitalization. Duplex ultrasound demonstrates an acute deep venous thrombosis of the lower extremity with phlegmasia and venous obstruction; a venous disorder code from this group is assigned to capture the acute venous occlusive process as part of the visit. Typical codes: I87.291, I87.299, I87.391.
    • A middle-aged patient with a long history of chronic venous insufficiency reports progressive bilateral leg heaviness, edema, skin hyperpigmentation, and varicose changes managed in the outpatient vascular clinic. The clinician documents chronic venous reflux and post-phlebitic changes without acute thrombosis, and assigns a chronic vein disorder code to reflect the ongoing venous dysfunction contributing to symptoms and treatment planning. Typical codes: I87.2, I87.8.
    • A postoperative patient on the medical-surgical floor develops limb swelling and pain and ultrasound shows a superficial thrombophlebitis at the site of a recent IV catheter; this is documented as a complication of the catheter and a venous disorder code is used to capture the localized thrombotic inflammation as a comorbidity affecting inpatient management. Typical codes: I87.0, I87.319.
