Underdosing of beta-adrenoreceptor antagonists, sequela

This code signifies a long-term consequence or complication arising from the insufficient administration or intake of beta-blocker medications. These sequelae are persistent conditions that develop after the initial underdosing event has passed. Examples include chronic cardiac arrhythmias or uncontrolled hypertension directly attributable to the past inadequate beta-blocker therapy.

Use this code when documenting a patient presenting with a chronic condition or permanent damage that is a direct result of a previous, prolonged period of underdosing beta-adrenoreceptor antagonists. This applies when the underdosing itself is no longer an active issue, but its lasting effects are being treated. It is appropriate for conditions like persistent angina or heart failure exacerbated by historical insufficient beta-blocker management.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past underdosing event of beta-blockers.
• Do not use for acute underdosing or when the underdosing is still ongoing; use an acute underdosing code for those scenarios.
