| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| E87.29 | Other acidosis | Use when anion gap is elevated (>12) and specific etiology is documented. |
|
| E87.22 | Chronic metabolic acidosis | Use for chronic conditions like CKD with persistent elevated anion gap. |

Primary ICD-10-CM Codes for anion gap metabolic acidosis
Decision Criteria
clinical Criteria
- Anion gap >12 with documented etiology.
coding Criteria
- Do not use if DKA is the primary diagnosis.
Clinical Validation Requirements
- Anion gap >12
- pH <7.35
- HCO3- <22
- Documented underlying cause
Code-Specific Risks
- Incorrectly coding when the cause is specified elsewhere, such as DKA.
Coding Notes
- Ensure documentation includes specific lab values and underlying causes.
E87.22 - Chronic metabolic acidosis
Use for chronic conditions like CKD with persistent elevated anion gap.
Applicable To
- Chronic anion gap metabolic acidosis
Clinical Validation Requirements
- Chronic anion gap >12 for more than 3 months
Coding Notes
Ensure chronicity is documented.
Ancillary Codes

R79.89Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Anion Gap Metabolic Acidosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E87.29.
Impact
Clinical: Inaccurate diagnosis representation., Regulatory: Potential audit issues., Financial: Incorrect reimbursement.
Mitigation Strategy
Use templates that prompt for specific lab values., Educate staff on documentation requirements.
Impact
Reimbursement: Incorrect DRG assignment., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Use E10.10 for DKA instead.
Impact
Risk of incomplete documentation leading to incorrect coding.
Mitigation Strategy
Implement thorough documentation templates and training.
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.
