CodeDescriptionWhen to UseKey Documentation
K31.7Polyp of stomach and duodenumUse for non-neoplastic gastric polyps unless histology confirms neoplasia.
  • Endoscopic findings of polyp
  • Histology confirming non-neoplastic nature
D13.1Benign neoplasm of stomachUse when biopsy confirms adenomatous or neoplastic nature of the polyp.
  • Biopsy confirming adenomatous nature
  • Pathology report indicating benign neoplasm

Clinical Decision Support

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

Applicable To

  • Hyperplastic gastric polyp
  • Inflammatory gastric polyp

Excludes

  • Colonic polyp (K63.5)
  • Gastric adenocarcinoma (C16.9)

Clinical Validation Requirements

  • Endoscopic findings of polyp

Code-Specific Risks

  • Incorrectly coding neoplastic polyps under K31.7

Coding Notes

  • Ensure histology results are reviewed to confirm non-neoplastic nature before using K31.7.

Ancillary Codes

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

Screening for malignant neoplasm of intestinal tract

Z12.11
Use when the polyp is found during a screening procedure.

Family history of malignant neoplasm of digestive organs

Z80.0
Use when there is a family history of gastrointestinal malignancy.

Differential Codes

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

Benign neoplasm of stomach

D13.1
Use when biopsy confirms adenomatous or neoplastic nature.

Polyp of stomach and duodenum

K31.7
Use K31.7 for non-neoplastic polyps.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Gastric Polyp to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code K31.7.

Impact

Clinical: Leads to potential misdiagnosis., Regulatory: Non-compliance with documentation standards., Financial: May result in denied claims.

Mitigation Strategy

Ensure detailed endoscopy reports., Verify histology results before coding.

Impact

Reimbursement: Incorrect coding may lead to reimbursement issues., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation Strategy

Review biopsy results to confirm the nature of the polyp before coding.

Impact

Coding without histology confirmation can lead to audit issues.

Mitigation Strategy

Ensure all polyps are biopsied and histology results are reviewed before coding.

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 Gastric Polyp

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

Screening EGD with incidental polyp

Specialty: Gastroenterology

Required Elements

  • Indication for procedure
  • Polyp location and size
  • Removal technique
  • Histology results

Example Documentation

Screening EGD for iron deficiency anemia: 8 mm hyperplastic polyp in gastric antrum removed with cold forceps. No dysplasia.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Polyp seen and biopsied.
Good Documentation Example
10 mm Paris IIa polyp in gastric fundus removed en bloc with cold snare. Margins clear. Biopsy pending.
Explanation
The good example provides specific details about the polyp's size, location, and removal method, which are essential for accurate coding.
