Code Classification

  • Diseases of the circulatory system
    (I00–I99)
    • Diseases of veins, lymphatic vessels and lymph nodes, not elsewhere classified
      (I80-I89)
      • Other venous embolism and thrombosis
        (I82)

I82.5Y is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of chronic embolism and thrombosis of unspecified deep veins of proximal lower extremity. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Unspecified diagnosis codes like I82.5Y 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.

Specific Coding Applicable to Chronic emblsm and thombos unsp deep veins of prox low extrm

Non-specific codes like I82.5Y require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for chronic emblsm and thombos unsp deep veins of prox low extrm:

  • Use I82.5Y1 for Chronic embolism and thrombosis of unspecified deep veins of right proximal lower extremity - BILLABLE CODE

  • Use I82.5Y2 for Chronic embolism and thrombosis of unspecified deep veins of left proximal lower extremity - BILLABLE CODE

  • Use I82.5Y3 for Chronic embolism and thrombosis of unspecified deep veins of proximal lower extremity, bilateral - BILLABLE CODE

  • Use I82.5Y9 for Chronic embolism and thrombosis of unspecified deep veins of unspecified proximal lower extremity - BILLABLE CODE

Patient Education


Deep Vein Thrombosis

Deep vein thrombosis, or DVT, is a blood clot that forms in a vein deep in the body. Most deep vein clots occur in the lower leg or thigh. If the vein swells, the condition is called thrombophlebitis. A deep vein thrombosis can break loose and cause a serious problem in the lung, called a pulmonary embolism.

Sitting still for a long time can make you more likely to get a DVT. Some medicines and disorders that increase your risk for blood clots can also lead to DVTs. Common symptoms are :

  • Warmth and tenderness over the vein
  • Pain or swelling in the part of the body affected
  • Skin redness

Treatment includes medicines to ease pain and inflammation, break up clots and keep new clots from forming. Keeping the affected area raised and applying moist heat can also help. If you are taking a long car or plane trip, take a break, walk or stretch your legs and drink plenty of liquids.
