Adverse effect of centr-acting/adren-neurn-block agnt, subs

This code signifies a harmful or unintended reaction experienced by a patient due to the therapeutic use of medications that affect the central nervous system or block adrenergic neurons. These adverse effects are occurring during a follow-up visit for the initial adverse event.

Apply this code when a patient presents for ongoing management, monitoring, or treatment of an adverse effect from a centrally-acting or adrenergic-neuron-blocking agent. This includes follow-up appointments for conditions like orthostatic hypotension, sedation, or gastrointestinal issues caused by these drug classes.

• Always sequence this code after the code for the specific manifestation of the adverse effect.
• Ensure the documentation clearly indicates the encounter is for follow-up care of the adverse effect, not the initial presentation.
• Verify the medication involved falls into the "centrally-acting and adrenergic-neuron-blocking agents" category.
