Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Decision Criteria
clinical Criteria
- Patient is on peritoneal dialysis
documentation Criteria
- Record states 'dependent on peritoneal dialysis'
Applicable To
- Peritoneal dialysis
Excludes
- Hemodialysis (Z99.2)
Clinical Validation Requirements
- Documentation of dialysis dependence
- Presence of a functioning dialysis catheter
Code-Specific Risks
- Ensure dialysis type is specified as peritoneal.
Coding Notes
- Ensure documentation specifies peritoneal dialysis to avoid confusion with hemodialysis.
N18.6 - End stage renal disease
Use for patients diagnosed with ESRD requiring dialysis.
Applicable To
- ESRD
Excludes
- Acute kidney failure (N17.-)
Clinical Validation Requirements
- eGFR <15
- Documentation of ESRD diagnosis
Coding Notes
Always sequence N18.6 before Z99.2.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Peritoneal Dialysis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code Z99.2.
Impact
Clinical: Leads to confusion about treatment modality., Regulatory: Non-compliance with documentation standards., Financial: Potential claim rejections.
Mitigation Strategy
Always specify 'peritoneal' in documentation., Use templates to ensure completeness.
Impact
Reimbursement: Incorrect sequencing can lead to claim denials., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate patient records.
Mitigation Strategy
Always code N18.6 before Z99.2.
Impact
Inadequate documentation of dialysis type and frequency.
Mitigation Strategy
Implement standardized templates for dialysis documentation.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
