The ICD-10 code for a patient who has undergone a left nephrectomy is Z90.5, which represents "Acquired absence of kidney." This code is crucial for documenting the patient's history of having had their left kidney removed, as it helps healthcare providers understand the patient's anatomical status. When coding this condition, it's essential to also include any underlying reason for the nephrectomy if known, such as malignant neoplasm of the kidney (C64.2 for left kidney) or other kidney disease that necessitated the removal 1, 2, 3, 4, 5. The Z90.5 code is vital for proper medical management since having a single kidney affects medication dosing, contrast studies, and overall kidney function monitoring. Patients with a single kidney require special consideration regarding nephrotoxic medications and may need more frequent monitoring of renal function. Key considerations in the management of these patients include:
- Medication dosing adjustments to avoid nephrotoxicity
- Regular monitoring of renal function
- Avoidance of contrast studies that may further compromise kidney function
- Close monitoring of blood pressure and cardiovascular risk factors, as patients with a single kidney are at increased risk of hypertension and cardiovascular disease 3. Overall, accurate coding and documentation of a patient's history of left nephrectomy are critical for ensuring optimal medical management and minimizing the risk of complications.
