Poisoning by anterior pituitary hormones

This code signifies an adverse reaction or overdose specifically due to hormones produced by the anterior pituitary gland. This includes conditions arising from the toxic effects of growth hormone, prolactin, thyroid-stimulating hormone (TSH), adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), or luteinizing hormone (LH) when administered exogenously.

Use this code when a patient presents with symptoms of toxicity or poisoning directly attributable to the therapeutic or non-therapeutic use of anterior pituitary hormones. Documentation should clearly state the specific anterior pituitary hormone involved, the intent (e.g., accidental, intentional self-harm, therapeutic misadventure), and the resulting adverse effects.

• Always code the specific manifestation of the poisoning first, followed by this code to identify the substance.
• Distinguish carefully between adverse effects of properly administered hormones (which would use E-codes for adverse effects) and true poisoning/overdose.
• Ensure documentation specifies "anterior pituitary hormones" to differentiate from posterior pituitary hormones or other endocrine agents.
