Chronic kidney disease, Stage III (moderate)

This code signifies a persistent and irreversible reduction in kidney function, specifically reaching Stage III, characterized by a moderately decreased glomerular filtration rate (GFR). Patients in this stage typically experience a GFR between 30 and 59 mL/min/1.73 m², indicating significant kidney damage.

Apply this code when documentation clearly indicates a diagnosis of chronic kidney disease and specifies Stage III, or when a GFR value within the 30-59 mL/min/1.73 m² range is consistently reported. This stage often involves symptoms such as fatigue, swelling, and changes in urination, which may be noted in the patient's record.

• Ensure the medical record explicitly states "Stage III" or provides GFR values consistent with this stage.
• Do not use this code for acute kidney injury or end-stage renal disease.
• Always code any associated complications or underlying causes of CKD, such as hypertension or diabetes, as additional diagnoses.
