Underdosing of unsp fibrinolysis-affecting drugs, sequela

This code signifies a long-term consequence or complication arising from the patient receiving an insufficient dose of an unidentifiable medication that influences fibrinolysis. This underdosing event, which occurred in the past, has led to a current health problem or condition. The specific drug involved is not documented.

Apply this code when a patient presents with a chronic condition or permanent damage directly attributed to a past instance of underdosing of an unspecified fibrinolysis-affecting drug. This is appropriate for conditions like persistent thrombotic events or other sequelae where the original underdosing is no longer an active treatment issue but its effects remain.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past underdosing event of a fibrinolysis-affecting drug.
• If the specific drug is known, a more precise code from the T45.6 category should be used instead.
