Adverse effect of other antihypertensive drugs, sequela

This code signifies a lasting complication or condition resulting from a past adverse reaction to an antihypertensive medication other than those specifically classified elsewhere. It indicates that the initial adverse effect has resolved, but a residual problem or permanent damage persists. This could include chronic organ damage, neurological deficits, or other long-term health issues directly attributable to the drug's adverse effect.

Apply this code when documenting a patient's current condition that is a permanent or long-term sequela of an adverse effect from an antihypertensive drug not otherwise specified. This is used after the acute phase of the adverse reaction has passed, and the patient is now being treated for the chronic consequences. Examples include persistent renal impairment following drug-induced acute kidney injury, or chronic neuropathy after a toxic reaction.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past adverse effect of an antihypertensive drug.
• Do not use this code for acute adverse effects; use the appropriate acute adverse effect code (e.g., T46.5X5A) for those scenarios.
