Underdosing of mineralocorticoids and their antag, subs

This code signifies a patient's adverse reaction or complication due to receiving an insufficient amount of mineralocorticoids or their antagonists, occurring during a follow-up visit for the initial underdosing event. It indicates that the patient is still experiencing effects or receiving ongoing care related to the inadequate dosage of these specific medications.

Apply this code when documenting a patient encounter where the underdosing of mineralocorticoids (e.g., fludrocortisone) or their antagonists (e.g., spironolactone, eplerenone) is being managed, monitored, or treated after the initial presentation. This includes situations where the patient is returning for adjustments to their medication regimen, assessment of persistent symptoms, or management of ongoing complications directly attributable to the previous underdosing.

• Ensure documentation clearly links the current encounter to the prior underdosing event.
• This "D" seventh character indicates subsequent care, not the initial presentation of the underdosing.
• Always code the specific manifestation of the underdosing (e.g., electrolyte imbalance, hypotension) as a primary or secondary diagnosis.
