Hypopituitarism

For severe panhypopituitarism with secondary adrenal insufficiency / myxedema-equivalent presentation (e.g., post-pituitary-apoplexy, post-traumatic, Sheehan syndrome), rate by analogy to DC 7903 (hypothyroidism manifesting as myxedema) — 100% continues for six months beyond date of crisis stabilization per § 4.119 Note (1) framework; thereafter rate residual effects under the appropriate body system DCs (eye, digestive, mental disorders, adrenal insufficiency DC 7911, diabetes insipidus DC 7909).

No dedicated diagnostic code under § 4.119 for hypopituitarism as a single entity; rate by analogy under § 4.119 (DC 7999). Each affected pituitary hormone axis is evaluated separately under the appropriate code: secondary hypothyroidism (DC 7903); secondary adrenal insufficiency (DC 7911); diabetes insipidus from posterior-pituitary involvement (DC 7909); secondary hypogonadism (DC 7999 by analogy); growth hormone deficiency (DC 7999 by analogy). Mass effect from an underlying tumor — visual-field deficits under § 4.79 (eye), cranial neuropathies under § 4.124a — is rated separately. The combined rating is determined under the combined ratings table at § 4.25.
