Complete code families applicable to Hypokalemia

E87.6Primary Range

Disorders of electrolyte and fluid balance, not elsewhere classified

Primary code for hypokalemia, used when no underlying cause is specified.

Chronic kidney disease (CKD)

Used to code underlying CKD when hypokalemia is a result of kidney disease.

Adverse effect of diuretics

Used to code hypokalemia due to diuretic use.

Key Information: ICD-10 code for hypokalemia

Essential facts and insights about Hypokalemia

The ICD-10 code for hypokalemia is E87.6, used when confirmed by lab results and symptoms. Code underlying causes first.

Decision Criteria

clinical Criteria

  • Serum potassium level <3.5 mEq/L

documentation Criteria

  • Documented symptoms or ECG changes

Applicable To

  • Low potassium

Excludes

  • Hyperkalemia (E87.5)
  • Disorders of magnesium metabolism (E83.5)

Clinical Validation Requirements

  • Serum potassium level <3.5 mEq/L
  • Symptoms such as muscle weakness or ECG changes

Code-Specific Risks

  • Coding without identifying underlying cause can lead to claim denials.

Coding Notes

  • Ensure to document the cause of hypokalemia and any related symptoms for accurate coding.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Chronic kidney disease, unspecified

N18.9
Use when CKD is the underlying cause of hypokalemia.

Adverse effect of diuretics

T50.2X5A
Use when diuretics are the cause of hypokalemia.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Hyperkalemia

E87.5
Hyperkalemia involves elevated potassium levels, opposite of hypokalemia.

Periodic paralysis

G72.3
Periodic paralysis may mimic hypokalemia symptoms but requires different treatment.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Hypokalemia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code E87.6.

Impact

Clinical: Inadequate treatment planning., Regulatory: Non-compliance with coding standards., Financial: Potential claim denials.

Mitigation Strategy

Always query for underlying conditions if not documented.

Impact

Reimbursement: May lead to claim denials or reduced reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate data representation of patient conditions.

Mitigation Strategy

Always code the underlying cause first if known, such as CKD or diuretic use.

Impact

Failure to code underlying cause first.

Mitigation Strategy

Regular training on coding guidelines and updates.

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.

Documentation Templates for Hypokalemia

Use these documentation templates to ensure complete and accurate documentation for Hypokalemia. These templates include all required elements for proper coding and billing.

Hypokalemia due to diuretics

Specialty: Nephrology

Required Elements

  • Serum potassium level
  • Underlying cause
  • Symptoms
  • Treatment plan

Example Documentation

Patient with K+ 2.8 mEq/L due to furosemide. Symptoms include muscle weakness. Plan: Oral potassium supplements.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Low potassium, give supplements.
Good Documentation Example
Hypokalemia (K+ 2.7 mEq/L) due to CKD stage 3 (N18.3), ECG shows U waves. Plan: IV K+ 10 mEq in 100mL NS over 1h.
Explanation
The good example provides specific lab values, underlying cause, and treatment plan.
