ICD-10 Code M31.11: Hematopoietic stem cell transplantation-associated thrombotic microangiopathy [HSCT-TMA]
M31.11 is a billable ICD-10 diagnosis code used to classify Hematopoietic stem cell transplantation-associated thrombotic microangiopathy [HSCT-TMA] in medical records and claims. You may see this code in hospital records, discharge summaries, insurance claims, encounter documentation, referrals, or other healthcare billing and coding records. ICD-10 codes are diagnosis classification codes used in healthcare records, reporting, coding workflows, and billing support. This code sits within the broader ICD-10 area for Diseases of the musculoskeletal system and connective tissue (M00-M99).
