| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| K22.89 | Other specified diseases of esophagus | Use when HRM confirms EGJOO with specific findings such as elevated IRP and impaired relaxation. |
|
| K22.0 | Achalasia of cardia | Use when HRM confirms achalasia with elevated IRP and aperistalsis. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Primary ICD-10-CM Codes for esophageal motility disorder
Decision Criteria
clinical Criteria
- HRM showing IRP >15 mmHg with incomplete LES relaxation
Applicable To
- Esophagogastric junction outflow obstruction (EGJOO)
Excludes
- Mechanical obstruction of esophagus (K22.2)
Clinical Validation Requirements
- High-resolution manometry (HRM) showing incomplete LES relaxation
- Impedance planimetry (FLIP) indicating impaired EGJ distensibility
Code-Specific Risks
- Misclassification as mechanical obstruction
Coding Notes
- Ensure documentation includes specific HRM findings to support this code.
K22.0 - Achalasia of cardia
Use when HRM confirms achalasia with elevated IRP and aperistalsis.
Applicable To
- Primary achalasia
Excludes
- Secondary achalasia due to other conditions
Clinical Validation Requirements
- HRM showing elevated IRP and 100% failed peristalsis
Coding Notes
Ensure HRM findings are documented to support achalasia diagnosis.
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 Esophageal Motility Disorder to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code K22.89.
Impact
Clinical: Leads to inaccurate diagnosis., Regulatory: Non-compliance with coding standards., Financial: Potential claim denials.
Mitigation Strategy
Always include HRM results in documentation., Review coding guidelines regularly.
Impact
Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Use K22.89 for motility disorders like EGJOO.
Impact
Lack of HRM findings can trigger audits.
Mitigation Strategy
Ensure all HRM results are documented and linked to diagnosis.
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.
