2025 ICD-10-CM code I82.3
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Diseases of veins, lymphatic vessels and lymph nodes - Other venous embolism and thrombosis Diseases of the circulatory system (I00-I99) Feed
Embolism and thrombosis of the renal vein.
Modifiers may apply depending on the circumstances of the encounter (e.g., bilateral involvement), but this is dependent on further clinical information.
Medical necessity for coding I82.3 is established through clinical evidence of renal vein thrombosis, supported by diagnostic imaging and laboratory findings.The presence of symptoms such as flank pain, hematuria, or signs of renal impairment, along with confirmation of thrombosis through imaging studies, justifies the coding.
The clinical responsibility for I82.3 rests with physicians specializing in nephrology (kidney disease) and/or vascular surgery, depending on the treatment approach.Diagnosis may involve imaging studies (ultrasound, CT scan) and blood tests.Treatment often entails anticoagulation therapy (blood thinners) to prevent clot propagation and potential complications.
- Diseases of the circulatory system (I00-I99)
- Diseases of veins, lymphatic vessels and lymph nodes, not elsewhere classified (I80-I89)
In simple words: A blood clot, either formed in the renal vein or traveling from elsewhere, is blocking the blood flow in the vein that drains blood from a kidney. This can harm the kidney.
This code signifies the presence of a blood clot (thrombosis) or a blockage caused by a traveling blood clot (embolism) within the renal vein, the vessel that carries blood away from the kidney.This condition can impede blood flow, potentially leading to kidney damage or dysfunction.It is crucial to differentiate this from other venous thromboembolic events affecting different parts of the circulatory system.
Example 1: A 65-year-old male patient presents with right flank pain, hematuria (blood in the urine), and elevated creatinine levels. Ultrasound reveals a thrombus in the right renal vein.Diagnosis: I82.3., A 40-year-old female patient, post-partum, develops sudden onset of left flank pain and fever.Imaging studies confirm left renal vein thrombosis.Diagnosis: I82.3., A 70-year-old patient with a history of nephrotic syndrome (kidney disease) is found to have bilateral renal vein thrombosis on CT scan. The patient is experiencing lower extremity edema. Diagnosis: I82.3.
Detailed history, physical examination findings (including signs of renal impairment), laboratory results (creatinine, BUN, blood counts, coagulation studies), and relevant imaging studies (ultrasound, CT scan, or venography) are essential for proper coding.Documentation must clearly identify the location of the thrombosis (renal vein) and specify if the event is unilateral or bilateral.
** The severity of renal vein thrombosis can vary widely, from asymptomatic cases to those requiring immediate intervention. Accurate coding necessitates detailed documentation of the clinical presentation, diagnostic findings, and treatment provided.
