Underdosing of oth hormones and synthetic substitutes, init

This code signifies a patient's condition resulting from taking an insufficient amount of a prescribed hormone or synthetic substitute, excluding adrenal cortical steroids, insulin, or estrogen/progestins. The underdosing leads to adverse effects or a worsening of the underlying condition the medication was intended to treat.

Apply this code when a patient presents with symptoms or complications directly attributable to not taking enough of their prescribed hormone therapy (e.g., thyroid hormone, growth hormone, testosterone) or other synthetic substitutes. This includes situations where the patient intentionally or unintentionally took less than the recommended dose, or if the prescribed dose was inadequate.

• Always assign an additional code for the specific adverse effect or manifestation of the underdosing.
• Ensure documentation clearly states the underdosing as the cause of the patient's current presentation.
• Verify that the encounter is the initial one for this specific underdosing episode.
