Compare key differences between these codes to ensure accurate selection

CodeDescriptionWhen to UseKey Documentation
K50.01Crohn's disease of small intestine with complicationsUse when Crohn's disease is confirmed as the etiology of ileitis with complications like strictures or fistulas.
  • Transmural inflammation
  • Discontinuous/skip lesions
  • Perianal involvement
K51.014Ulcerative colitis with backwash ileitisUse when ulcerative colitis is documented with backwash ileitis.
  • Continuous inflammation from cecum into ileum
  • No small bowel strictures

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

  • Presence of transmural inflammation and skip lesions

Applicable To

  • Crohn's ileitis with complications

Excludes

  • Ulcerative colitis with backwash ileitis (K51.014)

Clinical Validation Requirements

  • Transmural inflammation
  • Discontinuous/skip lesions
  • Perianal involvement

Code-Specific Risks

  • Ensure complications are documented to justify this code.

Coding Notes

  • Ensure documentation specifies Crohn's disease and any complications present.

Ancillary Codes

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

Partial intestinal obstruction

K56.690
Use when ileitis leads to partial obstruction.

Differential Codes

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

Ulcerative colitis with backwash ileitis

K51.014
Continuous inflammation extending from the cecum into the ileum, typically less than 5 cm.

Crohn's disease of small intestine with complications

K50.01
Presence of transmural inflammation and skip lesions.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Ileitis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code K50.01.

Impact

Clinical: May lead to inadequate treatment planning., Regulatory: Non-compliance with coding standards., Financial: Potential loss of reimbursement for complications.

Mitigation Strategy

Use detailed templates, Regular training on documentation standards

Impact

Reimbursement: May result in lower reimbursement if specific codes are not used., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases accuracy of clinical data.

Mitigation Strategy

Use specific codes like K50.01 or K51.014 when etiology is known.

Impact

Failure to document complications can lead to audit issues.

Mitigation Strategy

Implement thorough documentation practices and regular audits.

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.

Gastroenterology Progress Note

Specialty: Gastroenterology

Required Elements

  • Location of inflammation
  • Endoscopic features
  • Histologic findings
  • Complications

Example Documentation

**Location:** Terminal ileum (__ cm from IC valve) **Endoscopic Features:** [ ] Apthous ulcers [ ] Longitudinal ulcers [ ] Cobblestoning [ ] Pseudopolyps [ ] Friability [ ] Stricture (__ mm lumen) **Histologic Findings:** [ ] Transmural inflammation [ ] Granulomas [ ] Crypt abscesses [ ] Basal plasmacytosis [ ] Architectural distortion **Complications:** [ ] Fistula (Entero-___ type) [ ] Abscess (__ cm) [ ] Obstruction

Examples: Poor vs. Good Documentation

Poor Documentation Example
Ileitis present
Good Documentation Example
Severe active ileitis with apthous ulcers and non-caseating granulomas on biopsy, consistent with Crohn's disease. No strictures or fistulae noted.
Explanation
The good example provides specific findings and diagnosis, supporting accurate coding.
