What This Code Means

Excessive hormone production by the pituitary gland where the specific hormone involved is not identified or documented.

Coding Tips

• •This is a default code used when pituitary hyperfunction is documented but the specific hormone excess is unclear
• •Query the provider for clarification on which pituitary hormone is elevated to allow for more specific coding

Clinical Significance

Unspecified hyperfunction of the pituitary gland indicates documented pituitary hormone excess without identification of the specific hormone involved. This code suggests incomplete diagnostic workup or insufficient documentation and should prompt clinical clarification.

Documentation Requirements

• ✓Query the provider to identify which pituitary hormone is elevated.
• ✓Document available lab results, imaging findings, clinical symptoms suggesting specific hormone excess, and rationale if workup is still pending.
