Drug withdrawal

This code signifies a physiological and psychological syndrome that occurs upon the abrupt cessation or reduction of a psychoactive substance after prolonged or heavy use. It encompasses the constellation of symptoms experienced as the body adjusts to the absence of the drug.

Apply this code when a patient presents with symptoms directly attributable to the withdrawal from a substance, such as opioids, benzodiazepines, alcohol, or stimulants. Documentation should clearly indicate the substance involved and the manifestation of withdrawal symptoms, such as tremors, nausea, anxiety, or seizures.

• Always code the specific substance dependence or abuse (e.g., 304.x, 305.x) as the primary diagnosis when known, with this code as a secondary diagnosis.
• Do not use this code for drug-induced delirium or psychosis unless withdrawal is the underlying cause.
• Ensure documentation differentiates between withdrawal symptoms and intoxication or overdose.
