Medical records must be maintained and legible, include complete patient identification and dates of service, and include the legible signature of the responsible physician or non-physician practitioner.
The submitted medical record must support the selected ICD-10-CM code(s) and show medical necessity for the cystatin C test.
The laboratory or billing provider must retain a physician requisition that states the diagnosis/ICD-10-CM code that warrants the test.

Key Coverage Criteria

Cystatin C measurement is covered when medical record documents an adult patient (>=18 years) with a creatinine-based eGFR of 45–59 ml/min/1.73 m2 and no markers of kidney damage.
Cystatin C measurement is covered when the ordering documentation demonstrates that creatinine-based GFR estimates are believed to be inaccurate and more accurate GFR knowledge will affect clinical decision-making or the patient's plan of care.
