Appropriate Documentation of Renal Failure. Definitions: Stage III CKD: eGFR between 30–59 mL/min/1.73 m² for ≥ 3 months; Stage IV CKD: eGFR between 15–29 mL/min/1.73 m² for ≥ 3 months; Stage V CKD: eGFR 15< mL/min/1.73 m² for ≥ 3 months or dialysis dependence; Risk: Increased creatinine X 1.5 or eGFR decrease >25%; Injury: Increased creatinine X 2 or eGFR decrease >50%; Failure: Increased creatinine X 3 or eGFR decrease >75% or creatinine ≥ 4mg per 100ml (acute rise of ≥ 0.5 mg per 100ml). Note: RTN = Renal Template Note, eGFR = estimated glomerular filtration rate
