    I am having a difficult time trying to decide which icd-10 code to use for ALOC. Does anyone know what code to use?

    Hi ,

    We've -

    R40.4: Transient alteration of awareness

    R40.0: Somnolence (Drowsiness)

    R40.20: Unspecified Coma (Unconsciousness NOS)

    So, I would suggest R40.20 would be appropriate one.

    P.S.- An altered level of consciousness is any measure of arousal other than normal. Level of consciousness (LOC) is a measurement of a person's arousability and responsiveness to stimuli from the environment.

    Somnolence (alternatively "sleepiness" or "drowsiness") is a state of near-sleep, a strong desire for sleep, or sleeping for unusually long periods.

    Unconsciousness is a state which occurs when the ability to maintain an awareness of self and environment is lost. It involves a complete or near-complete lack of responsiveness to people and other environmental stimuli.

    Hope this helps!!!
