- ICD-10 Code for:
- Peripheral vascular disease, unspecified
- Is Billable?
- Yes - Valid for Submission

- Code Navigator:
I73.9 is a billable diagnosis code used to specify a medical diagnosis of peripheral vascular disease, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.
Unspecified diagnosis codes like I73.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Information
Intermittent Claudication
a symptom complex characterized by pain and weakness in skeletal muscle group associated with exercise, such as leg pain and weakness brought on by walking. such muscle limpness disappears after a brief rest and is often relates to arterial stenosis; muscle ischemia; and accumulation of lactate.Peripheral Arterial Disease
lack of perfusion in the extremities resulting from atherosclerosis. it is characterized by intermittent claudication, and an ankle brachial index of 0.9 or less.
Tabular List of Diseases and Injuries
The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.
Inclusion Terms
Inclusion TermsThese terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Intermittent claudication
- Peripheral angiopathy NOS
- Spasm of artery
Type 1 Excludes
Type 1 ExcludesA type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:
- The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
- The condition places limitations on self-care, independent living, and social interactions.
