What is the ICD-10 code for acute metabolic acidosis?

The ICD-10 code for acute metabolic acidosis is E87.21, used when specific lab values indicate acute severity.

How is chronic metabolic acidosis documented?

Chronic metabolic acidosis, coded as E87.22, requires documentation of persistent lab findings over 3 months.

Code	Description	When to Use	Key Documentation
E87.21	Acute metabolic acidosis	Use when acute metabolic acidosis is documented with specific lab values indicating severity.	Lactate >4 mmol/L AGAP >12 pH <7.35
E87.22	Chronic metabolic acidosis	Use when chronic metabolic acidosis is documented with persistent lab findings.	Bicarbonate <22 mEq/L over 3 months Stable AGAP 10-12
E87.20	Metabolic acidosis, unspecified	Use when documentation lacks specificity for acute or chronic acidosis.	pH <7.35 without specific lab values

Documentation & Coding Risks

Avoid these common issues when documenting Acidosis.

Vague documentation of acidosis

Impact

Clinical: May lead to inappropriate treatment., Regulatory: Increased audit risk., Financial: Potential for denied claims.

Mitigation

Educate clinicians on documentation specificity, Use templates for consistent documentation

Coding acidosis with diabetic ketoacidosis (DKA)

Impact

Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation

Do not code acidosis separately when DKA is present.

Using unspecified acidosis code

Impact

Reimbursement: May affect DRG assignment and reimbursement., Compliance: Potential audit risk., Data Quality: Lowers specificity of clinical data.

Mitigation

Ensure documentation specifies acute or chronic nature.

Specificity of acidosis coding

Impact

Risk of using unspecified codes due to vague documentation.

Mitigation

Implement documentation training and use of templates.
