CPT® Code 82043 is used to report quantitative measurement of microalbumin in urine, an important marker for early kidney damage, particularly in patients with diabetes or hypertension. Detecting microalbuminuria allows providers to identify renal dysfunction at an early stage and intervene before progression.
This code represents the laboratory analysis only, not specimen collection or interpretation services, which may be reported separately when appropriate.
Key Facts About CPT® 82043
- Service type: Laboratory test
- Test: Urine microalbumin (quantitative)
- Specimen type: Urine (spot or timed collection)
- Test purpose: Early detection of kidney disease
- Provider type: Laboratories, physicians, and qualified healthcare professionals
Common clinical indications:
- Screening for diabetic nephropathy
- Monitoring kidney function in patients with hypertension
- Evaluation of early renal disease
- Ongoing assessment of chronic kidney disease (CKD) risk
- Preventive care in high-risk populations
When to Use CPT® 82043
CPT 82043 is appropriate when:
- Measuring urine microalbumin levels quantitatively
- Screening patients at risk for kidney disease, especially those with diabetes
- Monitoring progression or treatment response in renal conditions
- Evaluating early signs of kidney damage before overt proteinuria develops
Examples:
- Annual microalbumin screening for a patient with type 2 diabetes
- Monitoring kidney function in a patient with long-standing hypertension
- Evaluating early renal changes in a high-risk patient
- Following up on previously elevated microalbumin levels
Documentation Requirements
To support CPT 82043 billing, documentation should include:
- Patient identifiers and date of service
- Clinical indication for testing
- Specimen type (e.g., spot urine or timed collection)
- Test performed (quantitative microalbumin)
- Test result and date reported
- Ordering provider information
Clear documentation supports medical necessity, accurate billing, and continuity of care.
Reimbursement and Coding Considerations
- CPT 82043 is generally covered when medically necessary, especially for diabetes management
- Frequently used in conjunction with creatinine testing (e.g., 82570) to calculate albumin-to-creatinine ratio (ACR)
- Diagnosis coding should support diabetes, hypertension, or kidney disease risk
- Often included in preventive care protocols for chronic disease management
- Frequency of testing may be guided by clinical guidelines and payer policy
Always verify payer-specific laboratory billing requirements.
