Underdosing of other estrogens and progestogens, init encntr

This code signifies a patient experiencing adverse effects or complications due to receiving an insufficient amount of other specified estrogen or progestogen medications. This underdosing can lead to a recurrence of the condition the medication was intended to treat or a lack of therapeutic effect.

Apply this code when documentation clearly indicates that a patient's current symptoms or condition are a direct result of not receiving the prescribed or therapeutically adequate dose of an estrogen or progestogen other than those specifically classified elsewhere. This is appropriate for the initial phase of treatment for the underdosing event.

• Always sequence this T-code as a secondary diagnosis, following the code for the specific condition being treated by the underdosed medication.
• Ensure the documentation specifies "underdosing" and not simply a lack of efficacy or non-compliance without adverse effects.
• Verify that the encounter is the initial one for the underdosing event, as indicated by the "A" seventh character.
