Without seeing all the documentation it is just a guess as to peripheral or thrombotic so let's compare the codes so you can decide.
What is the meaning of chronic microangiopathy?
Microangiopathy is
one of the major complications of diabetes mellitus. The small blood vessel changes affecting the retinal and renal vasculature are responsible for blindness and kidney failure. Microvascular pathology has also been assumed to play a role in diabetic neuropathy and in the so-called diabetic foot.

ICD-10-CM says the seventh character
S is “for use for complications or conditions that arise as a direct result of an injury,
For chronic microangiopathy, the ICD-10 index refers you to these codes.

Thrombotic
microangiopathy
What is Thrombotic microangiopathy?
Thrombotic microangiopathies (TMA) are clinical syndromes defined by the presence of hemolytic anemia (destruction of red blood cells), low platelets, and organ damage due to the formation of microscopic blood clots in capillaries and small arteries.
How is it diagnosed?
TMA often present very suddenly and result in severe illness in many patients. Patients are often hospitalized at the time of diagnosis. Diagnosis requires blood tests to confirm red blood cell destruction, the presence of schistocytes on blood smears, and organ damage that can be attributed to the TMA. Typical organ damage includes very high blood pressure (malignant hypertension), kidney injury, abdominal pain, diarrhea, stroke, confusion, heart injury, and eye damage. Identifying the specific cause for TMA requires specialized blood and genetic testing to evaluate for the different causative diseases. Some of this testing can take weeks to months to return. Since treatment must be initiated immediately, it is important to have a team of doctors experienced in the diagnosis and management of TMA. A team at Johns Hopkins has developed a research test that may be capable of diagnosing TMA due to problems in the complement system (aHUS) within several hours.

Approximate Synonyms
- Thrombotic microangiopathic
- Thrombotic thrombocytopenic purpura
Clinical Information
- A disorder characterized by the presence of microangiopathic hemolytic anemia, thrombocytopenic purpura, fever, renal abnormalities and neurological abnormalities such as seizures, hemiplegia, and visual disturbances. It is an acute or subacute condition.
- A kind of blood disorder that causes blood clots to form in blood vessels around the body
- An acquired, congenital, or familial disorder caused by platelet aggregation with thrombosis in terminal arterioles and capillaries. Clinical features include thrombocytopenia; hemolytic anemia; azotemia; fever; and thrombotic microangiopathy. The classical form also includes neurological symptoms and end-organ damage, such as renal failure.
- An acute or subacute syndrome characterized by the presence of microangiopathic hemolytic anemia, thrombocytopenic purpura, fever, renal abnormalities and neurologic abnormalities such as seizures, hemiplegia, and visual disturbances. Drugs and bacteria have been implicated as etiologic factors. The introduction of plasma exchange has significantly lowered the mortality rate. If untreated, the mortality rate is high.
- Diseases that result in thrombosis in microvasculature. The two most prominent diseases are purpura, thrombotic thrombocytopenic; and hemolytic-uremic syndrome. Multiple etiological factors include vascular endothelial cell damage due to shiga toxin; factor h deficiency; and aberrant von willebrand factor formation.
- The syndromes of microangiopathic hemolytic anemia, thrombocytopenia, and variable signs of organ impairment, due to platelet aggregation in the microcirculation.

Other cerebrovascular disease
Approximate Synonyms
- Acute ill-defined cerebrovascular disease
- Ill-defined cerebrovascular disease, acute
- Necrosis of central nervous system due to exposure to ionizing radiation
- Radiation necrosis of central nervous system (cns)
