Code Classification

  • Diseases of the circulatory system
    (I00–I99)
    • Diseases of veins, lymphatic vessels and lymph nodes, not elsewhere classified
      (I80-I89)
      • Phlebitis and thrombophlebitis
        (I80)

I80.00 is a billable diagnosis code used to specify a medical diagnosis of phlebitis and thrombophlebitis of superficial vessels of unspecified lower extremity. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like I80.00 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
