(Active) Effective Date: N/A Revision Date: N/A Laboratory - Chemistry Procedures Pathology and Laboratory Procedures > Chemistry Procedures Feed
Measurement of creatinine in a non-blood specimen (typically urine).
Modifiers may apply depending on the circumstances of service.For example, modifier 91 (repeat test) might be used if the test is repeated.
Medical necessity for this test is established when there is clinical suspicion of kidney disease, monitoring of known kidney disease, or need to assess kidney function as part of a broader assessment.The ordering physician should document the reason for ordering the test.
The clinical responsibility lies with the laboratory analyst who performs the test, interprets the results, and reports them to the ordering physician.
In simple words: This lab test measures the amount of creatinine in a urine sample (or other non-blood sample). Creatinine is a waste product from muscle use. This test helps check how well your kidneys are working.
This CPT code, 82570, reports the quantitative measurement of creatinine in a patient specimen other than blood.The specimen is typically urine.Methods may include quantitative enzymatic, Jaffe reaction, colorimetric assay, or manual methods. The test assesses creatinine levels, a byproduct of muscle metabolism, to evaluate kidney function.Higher levels may indicate kidney damage or disease, while lower levels can suggest other underlying health issues. Results are typically reported in mg/dL or other appropriate units.
Example 1: A patient presents with symptoms suggestive of kidney disease.A urine creatinine test (82570) is ordered to evaluate kidney function, along with a blood creatinine test and other renal function tests. The results are used to assess glomerular filtration rate (GFR)., A patient is undergoing regular monitoring for chronic kidney disease.A urine creatinine test (82570) is performed at each scheduled appointment to track the progression of the disease and adjust treatment as needed., A patient's urine albumin-to-creatinine ratio needs to be calculated. Both urine albumin and urine creatinine (82570) are ordered. The ratio helps detect early stages of kidney damage, particularly in patients with diabetes.
* Patient demographics.* Date and time of specimen collection (especially crucial for timed collections).* Specimen type and volume.* Relevant clinical information (if applicable).* Test method used.
** This code is primarily for urine creatinine; however, other non-blood sources could be used. Always confirm the specimen type with the laboratory and on the requisition.
