Billable Code

Decision Criteria

clinical Criteria

  • Heart rate increase ≥30 bpm within 10 minutes of standing

documentation Criteria

  • Document absence of orthostatic hypotension

Applicable To

  • POTS

Excludes

  • Ventricular tachycardia (I47.2)

Clinical Validation Requirements

  • Sustained heart rate increase ≥30 bpm within 10 minutes of standing
  • Absence of orthostatic hypotension
  • Symptoms improve rapidly upon recumbence

Code-Specific Risks

  • Incorrectly coding symptoms without confirming POTS criteria

Coding Notes

  • Ensure POTS criteria are met before coding G90.A.

Ancillary Codes

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

Tachycardia, unspecified

R00.0
Use for acute episodes of tachycardia in POTS.

Syncope and collapse

R55
Use for presyncope/syncope episodes related to POTS.

Differential Codes

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

Hyperthyroidism

E05.90
Rule out hyperthyroidism with normal TSH levels.

Anemia

D64.9
Exclude anemia with normal CBC results.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting POTS Syndrome to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code G90.A.

Impact

Clinical: Misdiagnosis of POTS., Regulatory: Non-compliance with coding standards., Financial: Potential claim denials.

Mitigation Strategy

Ensure orthostatic vitals are documented., Include absence of hypotension in notes.

Impact

Reimbursement: Incorrect coding may lead to reimbursement issues., Compliance: Non-compliance with coding guidelines., Data Quality: Affects the accuracy of clinical data.

Mitigation Strategy

Code G90.A only if consensus criteria are met.

Impact

Failure to document 3-month symptom duration for POTS.

Mitigation Strategy

Ensure all patient records include symptom duration.

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.

Frequently Asked Questions

Common questions about ICD-10 coding for POTS Syndrome, with expert answers to help guide accurate code selection and documentation.

Documentation Templates for POTS Syndrome

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

Patient with syncope and confirmed POTS

Specialty: Cardiology

Required Elements

  • Orthostatic vitals
  • Symptom details
  • Duration of symptoms
  • Exclusion of other conditions

Example Documentation

Patient reports daily presyncope. Orthostatic vitals: Supine HR 72, BP 110/70 → Standing HR 118 (Δ46 bpm), BP 108/68. Tilt-table test confirms POTS. TSH 1.2, ferritin 85. Assessment: G90.A (POTS), no anemia or thyroid dysfunction.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Patient has dizziness on standing.
Good Documentation Example
Orthostatic tachycardia (HR increase 45 bpm on standing) with lightheadedness and palpitations resolving within 2 minutes of lying down.
Explanation
The good example provides specific heart rate changes and symptom resolution, meeting POTS criteria.
