Underdosing of other hormone antagonists, sequela

This code signifies a patient's long-term health problems or conditions that have arisen as a direct consequence of not receiving enough of a prescribed hormone antagonist medication. These sequelae are persistent and manifest after the acute phase of underdosing has passed.

Apply this code when documenting chronic conditions or lasting adverse effects that are directly attributable to a historical underdosing of a hormone antagonist. This is appropriate for situations where the underdosing event itself is no longer active, but its lasting impact on the patient's health is being treated or monitored.

• 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 hormone antagonist.
• Do not use for acute underdosing events or for adverse effects from correctly administered medication.
