Underdosing of loop diuretics, subsequent encounter

This code signifies that a patient has received an insufficient amount of a loop diuretic, such as furosemide or bumetanide, during a subsequent encounter for the underdosing event. This underdosing can lead to inadequate fluid removal and worsening of conditions like edema or hypertension.

Use this code when a patient is seen for follow-up care related to a previously identified underdosing of a loop diuretic. This includes situations where the patient is experiencing ongoing symptoms due to insufficient diuretic therapy, or when adjustments are being made to their medication regimen after an underdosing incident.

• Ensure documentation clearly states the underdosing of a loop diuretic and that this is a follow-up visit.
• Always code the specific condition being treated by the loop diuretic (e.g., congestive heart failure, edema) as a primary or secondary diagnosis.
• Verify that the encounter type is "subsequent" as indicated by the 7th character "D".
