Underdosing of other antiprotozoal drugs, sequela

This code signifies a long-term or residual effect resulting from a patient not receiving an adequate dose of an antiprotozoal medication other than those specifically classified elsewhere (e.g., antimalarials, other antiprotozoals). These sequelae are the lasting consequences of insufficient treatment for a protozoal infection. The original underdosing event is no longer active, but its impact persists.

Apply this code when documenting a chronic condition or permanent damage directly attributable to a past instance of underdosing of an antiprotozoal drug. This would include situations where the protozoal infection recurred or worsened due to inadequate treatment, leading to ongoing health issues. It is used when the underdosing itself is no longer occurring, but its lasting effects are being treated or monitored.

• Always sequence this sequela code after the code for the specific condition or disease caused by the underdosing.
• Ensure documentation clearly links the current condition to a past underdosing event of an antiprotozoal drug.
• Do not use this code for acute underdosing; it is specifically for the long-term effects.
