M31.10 is a billable ICD-10 code used to specify a medical diagnosis of thrombotic microangiopathy, unspecified. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
Unspecified diagnosis codes like M31.10 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
- Thrombotic Microangiopathy-. a microvascular coagulopathy that may result from systemic vascular endothelial injury triggering the development of a procoagulant state, activation of the complement cascade, and microthrombi formation. signs may include hemolytic anemia, thrombocytopenia, hypertension and renal dysfunction.
- Transplant-Associated Thrombotic Microangiopathy|TA-TMA-. thrombotic microangiopathy that presents in some patients undergoing hematopoietic stem cell transplantation (hsct). though similar in presentation to thrombotic thrombocytopenic purpura (ttp) and atypical hemolytic uremic syndrome (ahus), transplant-associated thrombotic microangiopathy (ta-tma) is a distinct disorder. several risk factors may be associated with ta-tma, including high-dose chemotherapy, radiation therapy, hla mismatch, use of calcineurin inhibitors, acute graft-versus-host disease (gvhd), and infections.
