Underdosing of digestants, sequela

This code signifies a long-term consequence or complication arising from the patient's insufficient intake or administration of medications designed to aid digestion. These digestants typically include enzymes or other agents that facilitate the breakdown of food. The sequela indicates that the acute underdosing event has passed, but its lasting effects are still present and being treated.

Apply this code when documenting conditions such as chronic malabsorption, malnutrition, or persistent gastrointestinal distress that are directly attributed to a past, inadequate dosing of digestant medications. This is appropriate for follow-up encounters where the patient is being managed for these residual effects.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., K90.0 for celiac disease with malabsorption).
• Ensure documentation clearly links the current condition to a prior underdosing event of digestants.
• Do not use this code for active underdosing; refer to the acute underdosing codes for current situations.
