Underdosing of angiotens-convert-enzyme inhibitors, subs

This code indicates that a patient is experiencing an adverse health effect or complication due to receiving an insufficient amount of an angiotensin-converting-enzyme (ACE) inhibitor. This underdosing is not a new issue but rather a problem being addressed during a follow-up visit. The patient's condition is likely not improving or is worsening because the prescribed ACE inhibitor dosage is inadequate or was not taken as directed.

Use this code when documenting a patient's follow-up visit where the primary concern is the ongoing negative impact of an insufficient ACE inhibitor dosage. This could include scenarios where a patient is non-compliant with their medication regimen, the prescribed dose is found to be too low for their condition, or there's a documented error in medication administration leading to underdosing.

• Always ensure documentation clearly specifies "underdosing" and identifies the drug class as an ACE inhibitor.
• The "D" seventh character signifies a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Consider if an additional code for the specific adverse effect or condition being treated (e.g., uncontrolled hypertension) is also warranted.
