CodeDescriptionWhen to UseKey Documentation
K29.80Duodenitis without bleedingUse when duodenitis is confirmed without any evidence of bleeding.
  • Endoscopy findings of erythema or erosions without bleeding
  • Biopsy showing inflammation without hemorrhage
K29.81Duodenitis with bleedingUse when duodenitis is confirmed with evidence of bleeding.
  • Endoscopy showing active bleeding or erosions with hemorrhage
  • Clinical signs of GI bleeding such as hematemesis or melena

Clinical Decision Support

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

Decision Criteria

clinical Criteria

  • Endoscopy shows inflammation without bleeding.

Applicable To

  • Non-bleeding duodenitis

Excludes

  • Eosinophilic gastroenteritis (K52.81)

Clinical Validation Requirements

  • Endoscopy findings of erythema or erosions without bleeding
  • Biopsy showing inflammation without hemorrhage

Code-Specific Risks

  • Risk of undercoding if bleeding is not documented.

Coding Notes

  • Ensure documentation specifies absence of bleeding to use this code.

Ancillary Codes

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

Helicobacter pylori as the cause of diseases classified elsewhere

B96.81
Use when H. pylori infection is confirmed as a cause.

Iron deficiency anemia, unspecified

D50.9
Use if anemia is due to chronic blood loss from bleeding duodenitis.

Differential Codes

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

Gastric ulcer, unspecified as acute or chronic, without hemorrhage or perforation

K25.9
Ulcers are distinct from inflammation and require different treatment.

Duodenal ulcer, unspecified as acute or chronic, without hemorrhage or perforation

K26.9
Ulcers involve deeper tissue damage than inflammation.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Duodenitis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code K29.80.

Impact

Clinical: May lead to misdiagnosis or inappropriate treatment., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims or incorrect reimbursement.

Mitigation Strategy

Always specify the anatomical location of inflammation., Use precise medical terminology.

Impact

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

Mitigation Strategy

Query for clarification to confirm if bleeding is due to duodenitis.

Impact

Incomplete documentation of bleeding status can lead to incorrect coding.

Mitigation Strategy

Ensure all endoscopy reports and clinical notes specify bleeding status.

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 Duodenitis

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

Duodenitis with bleeding

Specialty: Gastroenterology

Required Elements

  • Symptoms
  • Endoscopic findings
  • Bleeding status
  • Etiology

Example Documentation

Patient presents with epigastric pain and melena. EGD shows friable duodenal mucosa with oozing blood. Biopsy indicates chronic inflammation.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Duodenal irritation noted.
Good Documentation Example
Duodenitis with active bleeding confirmed by EGD.
Explanation
The good example provides specific findings and confirms bleeding, supporting accurate coding.
