Measures the creatinine level in a blood sample to assess kidney function.
Modifiers may apply depending on the circumstances of the service. For example, modifier -90 (Reference laboratory) may be used when the test is performed at an outside laboratory.
Medical necessity for a creatinine test is established when there is a clinical indication suggesting potential kidney dysfunction or a need to monitor kidney health. This includes evaluating symptoms of kidney disease (e.g., fatigue, edema, decreased urine output), monitoring patients with known kidney disease or risk factors (e.g., diabetes, hypertension), assessing for side effects of nephrotoxic medications, or evaluating acute kidney injury. The test may also be part of a routine metabolic panel.
The clinical responsibility lies with the laboratory personnel who perform the test, analyze the results, and report the findings to the ordering physician. The physician interprets the results in the context of the patient's clinical presentation and overall health status to make a diagnosis or monitor treatment effectiveness.
In simple words: This blood test checks how well your kidneys are working by measuring the level of creatinine, a waste product made when your muscles break down. High levels might mean your kidneys aren't filtering waste properly.
This CPT code 82565 represents a laboratory procedure to quantitatively measure the creatinine concentration in a patient's blood specimen.Creatinine is a byproduct of creatine metabolism, primarily produced in muscle tissue. The kidneys filter creatinine from the blood, excreting it through urine.Elevated creatinine levels may indicate impaired kidney function, while decreased levels can sometimes suggest other underlying health issues.The test involves obtaining a blood sample, which is then analyzed using a quantitative method such as colorimetry or enzymatic assays. The reported result provides a numerical value representing the creatinine concentration, expressed in mg/dL or µmol/L. The obtained value is compared to established reference ranges to determine if it falls within the normal limit or indicates potential renal dysfunction.
Example 1: A patient presents with symptoms of fatigue, edema, and decreased urine output. A creatinine blood test is ordered to assess for potential renal impairment, aiding in the diagnosis of chronic kidney disease., A patient with a history of diabetes is undergoing regular monitoring of kidney function. Serial creatinine blood tests are performed to track any changes in kidney function and guide treatment adjustments., A patient is admitted to the hospital for acute kidney injury following a severe dehydration episode. Creatinine levels are closely monitored to assess the severity of renal impairment and guide fluid management and other supportive measures.

** Interpretation of creatinine results should always consider factors such as age, sex, muscle mass, and other medical conditions.It's vital to correlate this test with clinical findings and other laboratory results for accurate diagnosis and treatment planning. Normal ranges may vary slightly between laboratories.
