458.8
ICD-9-CMThis code signifies a diagnosis of low blood pressure that doesn't fit into more specific categories of hypotension, such as orthostatic, chronic, or iatrogenic. It encompasses various less common or ill-defined forms of hypotension that are clinically significant.
Use this code when documentation clearly indicates hypotension but the specific type is not precisely identified as orthostatic, chronic, or drug-induced. This applies to cases where the physician has diagnosed hypotension but the underlying cause or specific classification remains unspecified beyond a general "other specified" category.
