Underdosing of antigonadtr/antiestr/antiandrg, NEC, subs

This code indicates that a patient is experiencing an adverse outcome or complication due to taking less than the prescribed dose of medications that block the effects of hormones like gonadotropins, estrogens, or androgens. This underdosing is not due to a poisoning or overdose, but rather an insufficient therapeutic level.

Use this code for follow-up visits where the patient's condition is being managed or monitored after an initial underdosing event of these specific hormone-blocking agents. This applies when the underdosing is causing ongoing symptoms or requiring continued medical attention.

• Requires an additional code for the specific adverse effect or condition resulting from the underdosing.
• Ensure the documentation clearly states "underdosing" and specifies the type of medication (antigonadotrophin, antiestrogen, or antiandrogen).
• The "D" seventh character signifies a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
