Complete ICD-10-CM coding and documentation guide for Mesenteric Artery Stenosis. Includes clinical validation requirements, documentation requirements, and coding pitfalls.

Related ICD-10 Code Ranges

Complete code families applicable to Mesenteric Artery Stenosis

K55.0-K55.9Primary Range

Vascular disorders of intestine

This range includes chronic vascular insufficiency of the intestine, which encompasses mesenteric artery stenosis.

Atherosclerosis

This range includes atherosclerosis of other arteries, which may be used as an ancillary code when atherosclerosis is the underlying cause of mesenteric artery stenosis.

Code Comparison: When to Use Each Code

Compare key differences between these codes to ensure accurate selection

CodeDescriptionWhen to UseKey Documentation
K55.1Chronic vascular disorders of intestineUse when chronic mesenteric ischemia is confirmed by imaging and clinical symptoms.
  • Postprandial abdominal pain beginning 15-30 minutes after meals
  • Duplex ultrasound PSV >275 cm/s in SMA
  • CTA showing ≥70% stenosis in ≥2 mesenteric arteries
I70.8Atherosclerosis of other arteriesUse as an ancillary code when atherosclerosis is documented as the cause of stenosis.
  • Documentation of atherosclerosis as the underlying cause

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 postprandial pain and significant weight loss

coding Criteria

  • Confirmed imaging findings of ≥70% stenosis

documentation Criteria

  • Detailed symptom description and imaging results

Applicable To

  • Chronic mesenteric ischemia
  • Mesenteric artery stenosis

Excludes

  • Acute mesenteric ischemia (K55.0)

Clinical Validation Requirements

  • Postprandial abdominal pain beginning 15-30 minutes after meals
  • Duplex ultrasound PSV >275 cm/s in SMA
  • CTA showing ≥70% stenosis in ≥2 mesenteric arteries

Code-Specific Risks

  • Misclassification as acute ischemia
  • Lack of symptom documentation

Coding Notes

  • Ensure documentation specifies chronicity and imaging findings.

Ancillary Codes

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

Atherosclerosis of other arteries

I70.8
Use when atherosclerosis is specified as the underlying cause of mesenteric artery stenosis.

Differential Codes

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

Acute vascular disorders of intestine

K55.0
Sudden-onset abdominal pain, lactic acidosis, CT evidence of bowel wall thickening

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Mesenteric Artery Stenosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code K55.1.

Impact

Clinical: May lead to misdiagnosis., Regulatory: Non-compliance with coding standards., Financial: Potential claim denials.

Mitigation Strategy

Ensure imaging results are documented., Verify stenosis severity.

Impact

Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate clinical data affecting patient records.

Mitigation Strategy

Verify symptom duration and imaging findings to differentiate.

Impact

Inadequate symptom documentation can lead to audit findings.

Mitigation Strategy

Ensure detailed documentation of symptom onset, duration, and triggers.

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 Mesenteric Artery Stenosis

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

Chronic mesenteric ischemia evaluation

Specialty: Vascular Surgery

Required Elements

  • Patient history
  • Symptom description
  • Imaging results
  • Assessment and plan

Example Documentation

**Subjective**: 64F with 6-month history of postprandial epigastric pain (onset 15min post-meals, duration 2hrs), 25lb unintentional weight loss. No relief with PPIs. **Objective**: BMI 18.3 (-12% from baseline). Abdomen soft, non-tender at rest. **Imaging**: CTA shows 80% SMA stenosis, 70% celiac stenosis. Duplex SMA PSV 320 cm/s. **Assessment**: Chronic mesenteric ischemia due to atherosclerotic SMA/celiac stenosis. **Plan**: SMA stenting via right CFA access.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Patient has abdominal pain.
Good Documentation Example
Patient reports recurrent epigastric pain 20 minutes post-meals, lasting 2 hours, resolved with fasting.
Explanation
The good example provides specific timing and resolution details, supporting the diagnosis.
