Fourth degree hemorrhoids

This code represents the most severe form of hemorrhoidal disease, characterized by prolapsed internal hemorrhoids that cannot be manually reduced and remain permanently outside the anus. These often involve significant discomfort, bleeding, and potential complications like thrombosis or ulceration.

Use this code when documentation clearly indicates permanently prolapsed internal hemorrhoids that are irreducible. This diagnosis is typically made upon physical examination revealing the constant protrusion of hemorrhoidal tissue.

• Ensure documentation specifies "irreducible" or "permanently prolapsed" to differentiate from lesser degrees.
• Do not confuse with external hemorrhoids, which are coded differently.
• Consider sequencing this code as a primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity.
