Hypotension due to drugs

This code signifies abnormally low blood pressure that is directly attributable to the administration of a pharmaceutical agent. It represents an adverse effect or side effect of a drug, rather than hypotension from other underlying medical conditions. The patient experiences symptoms such as dizziness, syncope, or weakness due to the drug-induced drop in blood pressure.

Use this code when documentation clearly links the patient's hypotensive state to a specific medication. This often occurs in cases of drug overdose, adverse drug reactions, or therapeutic drug effects where hypotension is a known side effect. Supporting documentation should identify the causative drug and the temporal relationship between its administration and the onset of hypotension.

• Always code the specific drug causing the adverse effect using an external cause code (T36-T50 series) in conjunction with this code.
• Distinguish from hypotension due to other causes (e.g., I95.1 for orthostatic hypotension, I95.81 for postprocedural hypotension).
• Ensure documentation specifies "due to drugs" or similar phrasing to justify this specific etiology.
