Measures creatinine clearance in a patient specimen to assess kidney function.
Modifiers may apply based on specific circumstances; consult local guidelines.For example, modifier 90 might be used for an outside laboratory.
Medical necessity for a creatinine clearance test is established based on clinical presentation, symptoms, and risk factors suggestive of impaired kidney function.The test is indicated in patients with suspected or known kidney disease, diabetes, hypertension, or other conditions that may affect kidney function.It is also essential for monitoring the effectiveness of treatment in patients with existing kidney disease.The test may be medically necessary for pre- and post-operative assessments or when evaluating for kidney transplantation.
A clinical laboratory scientist or technician performs the creatinine clearance test.This involves collecting and processing the urine and blood samples, performing the appropriate assay to measure creatinine levels, and calculating the creatinine clearance rate. The results are then reported to the ordering physician for interpretation and clinical decision-making.
In simple words: This lab test measures how well your kidneys filter waste from your blood. It uses a urine sample and blood sample to see how efficiently your kidneys remove creatinine, a waste product, from your body.
This CPT code, 82575, represents the laboratory procedure for measuring creatinine clearance.Creatinine clearance is a test that assesses glomerular filtration rate (GFR), a key indicator of kidney function. The test involves analyzing a patient specimen (typically urine collected over a 24-hour period and a blood sample) to determine the rate at which creatinine, a waste product of muscle metabolism, is cleared from the blood by the kidneys. The results are expressed in milliliters per minute (mL/min) and provide valuable information for diagnosing and monitoring kidney diseases. Various methodologies may be employed, including quantitative enzymatic, Jaffe reaction, alkaline picrate, or colorimetric assays.The procedure helps in evaluating kidney function, diagnosing renal insufficiency, and monitoring the progression or treatment response of various kidney-related ailments.
Example 1: A patient presents with symptoms of kidney disease, such as edema and fatigue. The physician orders a creatinine clearance test to evaluate kidney function and assess the severity of the disease., A patient with a history of diabetes undergoes regular monitoring of kidney function through creatinine clearance testing. The test helps track the progression of diabetic nephropathy., A patient is being evaluated for possible kidney transplant. A pre-transplant assessment, including creatinine clearance test, is conducted to determine kidney function and suitability for transplantation.
* Patient demographics (age, gender, weight)* Relevant medical history (diabetes, hypertension, etc.)* Date and time of urine collection (24-hour collection required)* Urine volume measured accurately* Properly labeled blood sample* Detailed results of the creatinine assay in both blood and urine samples.* Calculation of the creatinine clearance rate using a standardized formula* Physician's order for the test
** The accuracy of the creatinine clearance result depends on the precise collection of a complete 24-hour urine specimen.Inaccurate collection can significantly alter the results.Various formulas exist to calculate the creatinine clearance, and the chosen formula must be specified in reporting.
