Underdosing of ganglionic blocking drugs, subs encntr

This code indicates a patient is experiencing adverse effects or complications due to taking less than the prescribed or recommended dose of a ganglionic blocking drug. This underdosing is causing a current health problem that requires medical attention.

Use this code when a patient presents for follow-up care, monitoring, or treatment of conditions directly resulting from insufficient intake of ganglionic blocking agents. This applies to situations where the underdosing is an ongoing issue or has led to persistent symptoms.

• Always use in conjunction with a code(s) for the specific manifestation(s) of the underdosing.
• Confirm the encounter is "subsequent" (e.g., follow-up, routine care during recovery) and not the initial treatment for the underdosing.
• Distinguish from poisoning (overdosing or wrong substance) or adverse effects from correct dosage.
