Excludes
- A09 (Infectious gastroenteritis)
Clinical Validation Requirements
- Negative infectious workup
- Clinical history of dietary or allergic cause
Coding Notes
Ensure non-infectious etiology is documented before using K52.9.

Applicable To
- Nausea with vomiting
Clinical Validation Requirements

Use as a symptom code when no definitive diagnosis is available.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Vomiting and Diarrhea to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code A09.
Impact
Clinical: May lead to inadequate treatment, Regulatory: Non-compliance with documentation standards, Financial: Potential loss of reimbursement for dehydration treatment
Mitigation Strategy
Always assess and document dehydration signs, Include capillary refill time and mucous membrane status
Impact
Reimbursement: May lead to lower reimbursement rates, Compliance: Non-compliance with coding guidelines, Data Quality: Inaccurate representation of patient conditions
Mitigation Strategy
Always code the underlying cause first, such as A09 for infectious gastroenteritis.
Impact
Using symptom codes as primary diagnosis instead of underlying cause
Mitigation Strategy
Educate coders on sequencing rules and provide regular audits
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.
