799.3
ICD-9-CMThis code represents a generalized state of weakness, feebleness, or lack of strength without a more specific underlying cause identified. It indicates a decline in physical function and overall vitality, often seen in elderly or chronically ill individuals.
Use this code when documentation clearly states "debility" or "generalized weakness" and no further diagnostic information is available to specify the etiology. It is often used in situations where the patient's primary problem is a decline in functional status, but a definitive diagnosis for that decline is not yet established or is not the focus of the current encounter.
