2025 ICD-10-CM code I73
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Diseases of arteries, arterioles and capillaries - Other peripheral vascular diseases Diseases of the circulatory system (I00-I99) Feed
Other peripheral vascular diseases; excludes chilblains, frostbite, immersion hand or foot, and cerebral artery spasm.
Modifiers may be applicable depending on the circumstances of the encounter (e.g., place of service, type of service). Consult the appropriate coding guidelines and payer-specific rules for appropriate modifier usage.
Medical necessity is established by the presence of symptoms and/or findings indicative of peripheral vascular disease.The severity of symptoms, impact on daily life, and potential for complications (e.g., limb ischemia, amputation) support the medical necessity of evaluation and treatment.
Diagnosis and management of peripheral vascular disease. This may involve physical examination, diagnostic testing (e.g., Doppler ultrasound, angiography), and treatment planning, which could include medication, lifestyle modifications, or surgical intervention.
- Diseases of the circulatory system (I00-I99)
- Diseases of arteries, arterioles and capillaries (I70-I79)
In simple words: This code means there's a problem with the blood vessels in your arms or legs, but the doctor doesn't know the exact problem yet.It's not frostbite, chilblains, or a specific problem with the arteries in your brain.
ICD-10-CM code I73 encompasses a range of peripheral vascular diseases not otherwise specified.This includes various disorders affecting blood vessels in the extremities, excluding conditions such as chilblains (T69.1), frostbite (T33-T34), immersion hand or foot (T69.0-), and cerebral artery spasm (G45.9). The code represents a broad category requiring further specification when possible using more specific codes within the I73 range (e.g., I73.0 for Raynaud's syndrome, I73.8 for other specified peripheral vascular diseases).
Example 1: A 60-year-old male presents with intermittent claudication (pain in the legs during exercise), cold feet, and decreased pulses in his lower extremities.After a physical examination and Doppler ultrasound, the physician diagnoses him with peripheral artery disease (PAD), unspecified, coded as I73.9., A 45-year-old female complains of numbness and tingling in her fingers and toes, particularly in cold weather.She experiences color changes in her digits.The physician diagnoses her with Raynaud's phenomenon (I73.0)., A 72-year-old patient with a history of diabetes presents with a non-healing ulcer on his foot.Vascular studies reveal significant peripheral vascular disease.The specific type of PVD cannot be determined definitively, leading to a code of I73.9.
Complete history and physical examination, including details about symptoms (e.g., pain, numbness, color changes, ulcerations), duration, and aggravating factors.Results of diagnostic tests like Doppler ultrasound, angiography, or other relevant imaging studies are essential for accurate coding.
** I73 is a broad code.Clinicians should strive to use more specific codes from the I70-I79 range whenever feasible to enhance the accuracy and granularity of medical billing data.Consult the official ICD-10-CM guidelines for the most up-to-date information.
