Adverse effect of anterior pituitary hormones, init encntr

This code signifies an undesirable or harmful reaction experienced by a patient due to the therapeutic use of hormones produced by the anterior pituitary gland. These hormones include growth hormone, prolactin, TSH, ACTH, FSH, and LH, and adverse effects can range from mild to severe.

Apply this code when a patient presents with symptoms directly attributable to an adverse reaction from a prescribed anterior pituitary hormone. This includes situations like allergic reactions, unexpected side effects, or toxicity from these medications, and it is the first time the patient is being seen for this specific adverse event.

• Always sequence this code first when it represents the primary reason for the encounter.
• Requires an additional code to identify the specific anterior pituitary hormone involved (e.g., from T38.0-T38.7).
• Ensure documentation clearly links the adverse effect to the therapeutic use of the anterior pituitary hormone, distinguishing it from poisoning or underdosing.
