Underdosing of enzymes, initial encounter

This code signifies a patient experiencing adverse effects due to receiving an insufficient amount of prescribed enzymes. This underdosing can lead to a worsening of the underlying condition for which the enzymes were prescribed, as the body is not receiving adequate enzymatic support.

This code is appropriate for documenting the initial presentation of symptoms or complications directly attributable to a patient not receiving enough of their prescribed enzyme medication. Examples include pancreatic enzyme replacement therapy (PERT) underdosing in cystic fibrosis patients leading to malabsorption, or underdosing of enzyme replacement therapy for lysosomal storage disorders.

• Ensure documentation clearly links the patient's current symptoms or condition to the underdosing of enzymes.
• This "initial encounter" seventh character is used while the patient is receiving active treatment for the underdosing.
• Consider an additional code for the specific adverse effect or complication resulting from the enzyme underdosing.
