Underdosing of hemostatic drugs, subsequent encounter

This code indicates that a patient experienced an adverse effect or complication due to receiving an insufficient amount of a hemostatic drug during a previous encounter. Hemostatic drugs are medications used to promote blood clotting and stop bleeding. Underdosing means the prescribed or administered dose was less than what was therapeutically required.

Use this code when documenting a patient's follow-up visit for issues directly related to an inadequate dose of a hemostatic agent. This could include continued bleeding, re-bleeding, or other complications arising from the drug's insufficient effect. It is appropriate for situations where the underdosing occurred in the past and the patient is now presenting for ongoing management.

• Always sequence this code after the primary diagnosis describing the condition being treated with the hemostatic drug.
• Ensure documentation clearly links the patient's current symptoms or condition to the previously inadequate hemostatic drug dosage.
• The "D" seventh character signifies a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase of the underdosing.
