Code Classification

  • Diseases of the circulatory system
    • Diseases of veins, lymphatic vessels and lymph nodes, not elsewhere classified
      • Varicose veins of lower extremities

I83.899 is a billable diagnosis code used to specify a medical diagnosis of varicose veins of unspecified lower extremity with other complications. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

The code I83.899 is applicable to adult patients aged 15 through 124 years inclusive. It is clinically and virtually impossible to use this code on a patient outside the stated age range.

Unspecified diagnosis codes like I83.899 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.

Clinical Classification

Clinical Information

  • Livedo Reticularis

    a condition characterized by a reticular or fishnet pattern on the skin of lower extremities and other parts of the body. this red and blue pattern is due to deoxygenated blood in unstable dermal blood vessels. the condition is intensified by cold exposure and relieved by rewarming.
  • Livedoid Vasculopathy

    a rare cutaneous thrombotic disease due to occlusion of dermal vessels. it is characterized by purpuric maculae and ulcerations especially during summer which form scars called atrophie blanche. it is more associated with other syndromes (e.g., protein c deficiency; hyperhomocysteinemia). livedo reticularis with systemic involvement and stroke is sneddon syndrome.
  • Sneddon Syndrome

    a systemic non-inflammatory arteriopathy primarily of middle-aged females characterized by the association of livedo reticularis, multiple thrombotic cerebral infarction; coronary disease, and hypertension. elevation of antiphospholipid antibody titers (see also antiphospholipid syndrome), cardiac valvulopathy, ischemic attack, transient; seizures; dementia; and chronic ischemia of the extremities may also occur. pathologic examination of affected arteries reveals non-inflammatory adventitial fibrosis, thrombosis, and changes in the media. (from jablonski, dictionary of syndromes & eponymic diseases, 2d ed; adams et al., principles of neurology, 6th ed, p861; arch neurol 1997 jan;54(1):53-60)
  • Skin Pigmentation

    coloration of the skin.
  • Livedo Reticularis

    a recurrent purple discoloration of the skin that does not blanche and is found in a lacy, network pattern, most often in the lower extremities. it may be aggravated by exposure to cold and is classified as idiopathic or secondary. secondary livedo reticularis may be a cutaneous manifestation of immune system disorders (e.g., lupus erythematosus, rheumatoid arthritis, cryoglobulinemia, lymphoma, etc), and hematologic disorders (polycythemia vera).
  • Skin Pigmentation

    the color of the skin as determined by the amount of melanin present.
  • Skin Pigmentation Disorder|Pigmentation Disorders

    a disorder of the skin characterized by loss or reduction of the skin color. it is caused by loss of melanocytes or abnormalities in melanin production.

Code Edits

The Medicare Code Editor (MCE) detects and reports errors in the coding of claims data. The following ICD-10-CM Code Edits are applicable to this code:

  • Adult diagnoses - The Medicare Code Editor detects inconsistencies in adult cases by checking a patient's age and any diagnosis on the patient's record. The adult code edits apply to patients age range is 15–124 years inclusive (e.g., senile delirium, mature cataract).

[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.
