Chronic kidney disease, Stage II (mild)

This code signifies a persistent reduction in kidney function, specifically categorized as Stage II. At this stage, the glomerular filtration rate (GFR) is mildly decreased, typically between 60 to 89 mL/min/1.73 m², indicating early kidney damage. Patients may be asymptomatic or present with subtle signs such as proteinuria.

Assign this code when documentation confirms a diagnosis of chronic kidney disease with a GFR consistently falling within the Stage II range. Supporting documentation includes laboratory results showing a GFR between 60-89 mL/min/1.73 m² and a physician's explicit diagnosis of CKD Stage II. This code is appropriate for ongoing management of mild kidney impairment.

• Always confirm the specific stage of CKD based on documented GFR values and physician's assessment.
• Do not use this code for acute kidney injury; it is strictly for chronic conditions.
• Sequence this code as a secondary diagnosis when another condition is the primary reason for the encounter, unless the CKD is the primary focus of treatment.
