Underdosing of unsp systemic anti-infect/parasit, subs

This code signifies that a patient is experiencing an adverse effect due to receiving an insufficient amount of an unspecified systemic anti-infective or antiparasitic medication. This underdosing is causing a current problem or complication that requires medical attention.

Apply this code when documenting a patient encounter for a condition resulting from the underdosing of an anti-infective or antiparasitic medication, and the specific drug is not known or not documented. This is for subsequent encounters where the initial treatment of the underdosing or its effects is ongoing.

• Always sequence this code after the code for the specific adverse effect or complication caused by the underdosing.
• Ensure documentation clearly indicates "underdosing" and that the encounter is for ongoing care related to this issue.
• Avoid using this code if the specific anti-infective or antiparasitic agent is known; instead, use the more specific underdosing code for that drug.
