Withdrawal codes

  • SMW
  • Cargo


  • Categories
  • This category indicates that the patient has current withdrawal symptoms or syndrome for the indicated substance.
  • While withdrawal USUALLY goes along with chronic abuse/dependence/addiction, there are drugs where one may get withdrawal symptoms after a first use (e.g. methamphetamines)
    • Thus, if (as will often but not universally be the case) a person in withdrawal does have a chronic abuse/dependence/addiction for that substance, you SHOULD also code that.
