ICD-10 Code I73.89 – Other specified peripheral vascular diseases (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I73.89 – Other specified peripheral vascular diseases
What it is
I73.89 identifies peripheral vascular disease that does not fit a more specific ICD-10 category. Use it for documented vascular disorders affecting the limbs or peripheral circulation when the record names another specified condition.
Clinical signs
Findings may include reduced peripheral pulses, limb pain, color change, coldness, or exertional symptoms. Clinical features vary; refer to documentation and the provider’s specified vascular diagnosis.
When to use this code
Use this code when the clinician documents a peripheral vascular disorder that is specified but not described by a more detailed code. It is appropriate when the note clearly identifies a peripheral vascular disease and excludes more common categories such as peripheral arterial disease or Raynaud syndrome. Check documentation if the terminology is vague.
Do not use for
Do not use I73.89 for unspecified peripheral vascular disease or for conditions with their own specific ICD-10 code. If the chart only says “vascular disease” without further detail, check documentation.
Coding tip
Code the most specific peripheral vascular diagnosis documented, and verify that I73.89 is not being used as a default for an unclear record.
