CodeDescriptionWhen to UseKey Documentation
K91.1Postgastric surgery syndromesUse when documenting dumping syndrome following gastric surgery.
  • Sigstad score ≥7
  • Postprandial tachycardia ≥10 BPM increase
  • Reactive hypoglycemia <70 mg/dL 2h post-meal
Z98.84Bariatric surgery statusUse as a primary code when documenting a history of bariatric surgery.
  • History of bariatric surgery documented

Clinical Decision Support

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

Ancillary Codes

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

Nausea with vomiting

R11.2
Use if nausea and vomiting are present as symptoms.

Diarrhea, unspecified

R19.7

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Dumping Syndrome to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code K91.1.

Impact

Clinical: Inadequate information for diagnosis., Regulatory: Potential for audit issues., Financial: Denied claims due to lack of specificity.

Mitigation Strategy

Use specific terms like 'postprandial tachycardia'., Document exact timing of symptoms.

Impact

Reimbursement: Incorrect sequencing can lead to denied claims., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate patient records and data reporting.

Mitigation Strategy

Always sequence Z98.84 before K91.1 for post-bariatric surgery cases.

Impact

Incorrect sequencing of post-surgical codes.

Mitigation Strategy

Educate staff on proper sequencing rules.

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.
