Underdosing of other laxatives, subsequent encounter

This code indicates that a patient is experiencing adverse effects or complications due to not taking enough of an "other" type of laxative. This underdosing is occurring during a subsequent encounter for the same condition, meaning the patient is returning for follow-up care related to the initial underdosing event.

Use this code when a patient presents for ongoing management of symptoms (e.g., persistent constipation, bowel obstruction risk) directly attributable to insufficient intake of a non-stimulant, non-saline, non-bulk-forming, or non-emollient laxative. This applies to follow-up visits after the initial underdosing was identified and treatment or monitoring was initiated.

• Requires a seventh character "D" for subsequent encounter, indicating ongoing care.
• Always sequence this code after the code for the specific adverse effect or condition resulting from the underdosing.
• Ensure documentation clearly specifies "underdosing" and the type of laxative, if known, to differentiate from non-compliance or therapeutic failure.
