Undrdose of antimalari/drugs acting on bld protzoa, sequela

This code signifies a patient's current health condition or complication that is a direct result of insufficient or inadequate administration of antimalarial medications or drugs targeting other blood protozoa. This underdosing could be due to various reasons, leading to a persistent or recurring parasitic infection or related sequelae.

Use this code when documenting a long-term effect or consequence directly attributable to a past instance of underdosing of antimalarial or antiprotozoal drugs. This applies to conditions like chronic malaria, persistent babesiosis, or other protozoal infections that have become difficult to treat due to suboptimal past drug regimens. It should be used as a secondary diagnosis to describe the etiology of the current condition.

• Always assign a primary diagnosis code for the specific condition or disease being treated.
• This "S" (sequela) seventh character indicates that the underdosing event itself is in the past, but its effects are still present.
• Do not use this code for acute underdosing events; instead, use the appropriate acute underdosing code without the "S" seventh character.
