Underdosing of antacids and anti-gstrc-sec drugs, subs

This code signifies a patient's underdosing of non-specific antacids or other medications that reduce gastric acid secretion, occurring during a follow-up visit for the underdosing event. It indicates that the patient did not take enough of the prescribed medication, leading to a recurrence or persistence of symptoms related to gastric acidity.

Use this code when documenting a patient presenting for a follow-up appointment after an initial underdosing of medications like antacids, H2 blockers, or proton pump inhibitors (other than those specifically classified elsewhere). This applies when the underdosing has resulted in ongoing or worsening gastrointestinal symptoms.

• Always use in conjunction with a code for the specific adverse effect or condition resulting from the underdosing.
• Ensure documentation clearly states "underdosing" and specifies the type of medication (e.g., antacid, anti-gastric-secretion drug).
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
