Postprocedural hypopituitarism

This code signifies a deficiency of one or more pituitary hormones that develops as a direct consequence of a medical procedure. This typically involves damage to the pituitary gland or its stalk, leading to impaired hormone production and subsequent endocrine dysfunction.

Apply this code when documentation explicitly links hypopituitarism to a prior surgical intervention (e.g., hypophysectomy, craniotomy near the sella turcica) or radiation therapy affecting the pituitary. The medical record must clearly state the cause-and-effect relationship between the procedure and the onset of pituitary insufficiency.

• Always sequence this code after the code for the underlying condition or reason for the original procedure, if applicable.
• Do not confuse with spontaneous or congenital hypopituitarism (E23.0), which is not procedure-related.
• Ensure documentation specifies the type of procedure that led to the hypopituitarism for accurate code assignment.
