In simple words: This code describes a long-term problem with blood clots in the deep veins of the arm.Blood clots can block blood flow, potentially leading to pain, swelling, and other complications.

This code signifies chronic blood clot formation (thrombosis) and blockage (embolism) within the deep veins of the upper extremity (arm).This can affect the brachial, radial, or ulnar veins.The condition is considered chronic, indicating long-standing presence rather than an acute event.

Example 1: A 60-year-old woman presents with persistent swelling and pain in her right arm, lasting for several months.Ultrasound reveals chronic thrombosis of the deep veins of the right upper extremity., A 45-year-old male patient with a history of recurrent superficial thrombophlebitis experiences a new onset of deep vein thrombosis in his left arm.He has significant arm swelling and pain., A 72-year-old patient who recently underwent a mastectomy develops a deep vein thrombosis in the affected arm. The patient presents with edema, pain, and discoloration of the arm.

Detailed patient history including risk factors (e.g., surgery, immobilization, malignancy, inherited clotting disorders), physical examination findings (e.g., edema, tenderness, warmth, discoloration), imaging studies (e.g., ultrasound, venography), laboratory results (e.g., coagulation studies), and treatment plan.

** This code should not be used for acute deep vein thrombosis of the upper extremity.For those cases, I82.4 would be more appropriate. Always consider using additional codes to capture co-morbidities or other relevant clinical findings.
