Acute Kidney Injury Documentation Guide
Sudden decline in kidney function with elevated creatinine or decreased urine output.
ICD-10 Codes: N17.0, N17.1, N17.2, N17.9
Common Symptoms
- Decreased urine output
- Fluid retention
- Nausea
- Fatigue
- Confusion
- Edema
Key Documentation Elements
- KDIGO stage (1, 2, or 3)
- Baseline and current creatinine
- Urine output measurements
- Etiology (prerenal, intrinsic, postrenal)
- Volume status assessment
- Nephrotoxin exposure review
Documentation Challenges
- Staging AKI severity using KDIGO criteria
- Documenting baseline creatinine and trajectory
- Identifying and recording the underlying etiology
- Tracking fluid balance and urine output trends
Billing Considerations
- KDIGO stage-specific coding (N17.0 tubular necrosis, N17.1 cortical necrosis, N17.2 medullary necrosis)
- Documentation of acuity for appropriate E&M level
- Dialysis documentation if initiated
- Underlying cause documentation for accurate coding
Frequently Asked Questions
How is AKI staged for documentation purposes?
AKI uses KDIGO staging: Stage 1 (creatinine 1.5-1.9x baseline), Stage 2 (2-2.9x), Stage 3 (3x or dialysis). Scribeable identifies the stage from documented labs and applies the correct N17.x code.
How does Scribeable help with AKI documentation?
Scribeable captures creatinine trends, urine output, volume status, and suspected etiology from your encounter to generate properly coded AKI documentation with KDIGO staging.
