Decision Criteria

clinical Criteria

  • Histological confirmation of Brunner's gland hyperplasia

documentation Criteria

  • Document absence of dysplasia or malignancy

Applicable To

  • Brunner's gland hyperplasia

Excludes

  • Benign carcinoid tumor of duodenum (D3A.010)
  • Benign stromal tumors of digestive system (D21.4)

Clinical Validation Requirements

  • Histological confirmation of Brunner's gland hyperplasia
  • Absence of dysplasia or malignancy

Code-Specific Risks

  • Misclassification as hamartoma or adenoma without histological confirmation

Coding Notes

  • Ensure histological confirmation to avoid misclassification.

Ancillary Codes

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

Adult hypertrophic pyloric stenosis

K31.1
Use if Brunner's gland hyperplasia causes gastric outlet obstruction.

Melena

K92.1
Use if Brunner's gland hyperplasia presents with bleeding.

Differential Codes

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

Benign carcinoid tumor of duodenum

D3A.010
Use when histology confirms carcinoid tumor characteristics.

Benign stromal tumors of digestive system

D21.4
Use when histology confirms stromal tumor characteristics.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Brunner's Gland Hyperplasia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code D13.2.

Impact

Clinical: May lead to incorrect diagnosis and treatment., Regulatory: Non-compliance with documentation standards., Financial: Potential claim denials due to lack of supporting documentation.

Mitigation Strategy

Ensure biopsy results are included in the medical record., Verify documentation before coding.

Impact

Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data recording.

Mitigation Strategy

Use K63.5 (Polyp of intestine) until histology confirms Brunner's gland hyperplasia.

Impact

Coding D13.2 without histological confirmation is a high audit risk.

Mitigation Strategy

Always require and document biopsy results 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 Brunner's Gland Hyperplasia

Use these documentation templates to ensure complete and accurate documentation for Brunner's Gland Hyperplasia. These templates include all required elements for proper coding and billing.

Gastroenterology Progress Note

Specialty: Gastroenterology

Required Elements

  • Size and location of lesion
  • Histology findings
  • Presence or absence of dysplasia

Example Documentation

Findings: 2.5 cm sessile duodenal bulb lesion with 'cobblestone' mucosa. Biopsy shows clustered Brunner glands with foamy cytoplasm, negative for Paneth cells or nuclear atypia. No H. pylori identified. Impression: Brunner's gland hyperplasia (D13.2) with reactive duodenitis (K29.80).

Examples: Poor vs. Good Documentation

Poor Documentation Example
Duodenal polyp seen on EGD.
Good Documentation Example
4 cm pedunculated duodenal bulb polyp with histology showing Brunner gland hyperplasia (CDX2+, MUC6+), no dysplasia.
Explanation
The good example provides specific histological findings and confirms the absence of dysplasia, supporting the use of D13.2.
