Oncology & Hematology Coding Alert

Your oncologist may frequently diagnose a deep vein thrombosis (DVT) in cancer patients. This is because clots may form as a result of blood vessel injury due to surgery or chemotherapy or some cancer treatments that may reduce the production of natural anticoagulants helping keep the blood fluid. Cancers of the lymphatic system, liver, ovaries, pancreas, and stomach are specifically known to increase the risk of DVT.

What to look for to justify the dx: Your physician may document symptoms like pain, swelling, redness, and warmth in the lower leg or area involved in DVT. In addition, your physician may also document that the superficial veins were engorged. Remember, superficial veins may be engorged even if the thrombus is in the deep veins. However, make sure your physician has specifically documented the diagnosis of DVT as many patients may not have any of the usual symptoms.
