  • Gastric emptying scintigraphy showing >10% retention at 4 hours
  • Exclusion of mechanical obstruction via EGD
E10.43Type 1 diabetes mellitus with diabetic autonomic (poly)neuropathyUse when gastroparesis is due to Type 1 diabetes.
  • HbA1c >6.5%
  • Documentation of autonomic neuropathy
E11.43Type 2 diabetes mellitus with diabetic autonomic (poly)neuropathyUse when gastroparesis is due to Type 2 diabetes.
  • HbA1c >6.5%
  • Documentation of autonomic neuropathy

Clinical Decision Support

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

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Delayed Gastric Emptying to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code K31.84.

Impact

Clinical: May lead to misdiagnosis or inappropriate treatment., Regulatory: Non-compliance with coding standards., Financial: Potential claim denials due to insufficient documentation.

Mitigation Strategy

Ensure all test results are documented, Use specific language linking symptoms to test findings

Impact

Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate representation of patient conditions.

Mitigation Strategy

Link with 'due to' language and use E10.43 or E11.43 with K31.84.

Impact

Reimbursement: May affect DRG assignment and reimbursement., Compliance: Non-compliance with sequencing rules., Data Quality: Misrepresentation of primary diagnosis.

Mitigation Strategy

Sequence K31.84 first if gastroparesis is the focus.

Impact

Lack of documented scintigraphy results can lead to audit issues.

Mitigation Strategy

Ensure all GES results are included in patient records.

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.

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

Diabetic Gastroparesis

Specialty: Endocrinology

Required Elements

  • Symptoms
  • GES results
  • Diabetes management
  • Exclusion of obstruction

Example Documentation

**Subjective**: 'Worsening postprandial vomiting x 3mo, early satiety after ½ cup food.' **Objective**: BMI 18.3 (↓2kg in 6mo), GES: 52% retention at 4hrs (normal <10%), EGD: No obstruction, retained food despite 12hr fast **Assessment**: Idiopathic gastroparesis (K31.84) **Plan**: Start metoclopramide; repeat GES in 6mo

Examples: Poor vs. Good Documentation

Poor Documentation Example
Patient has slow stomach emptying.
Good Documentation Example
Gastric emptying scintigraphy showed 45% retention at 4 hours, confirming gastroparesis. No mechanical obstruction on EGD.
Explanation
The good example provides specific test results and excludes mechanical obstruction, meeting documentation requirements.
