Unspecified thrombosed hemorrhoids

This code signifies the presence of hemorrhoids that have developed a blood clot (thrombosis) within them, but without further specification regarding their location (internal or external) or degree of prolapse. It indicates an acute, painful condition resulting from obstructed blood flow within the hemorrhoidal veins.

This code is appropriate when documentation clearly states "thrombosed hemorrhoids" without additional details that would allow for a more specific ICD-9-CM code. It is used when the physician's notes confirm the presence of a thrombosed hemorrhoid but do not differentiate between internal or external, or specify complications like ulceration or gangrene.

• Avoid using this code if the documentation specifies whether the thrombosed hemorrhoid is internal (e.g., 455.0, 455.2, 455.4) or external (e.g., 455.5, 455.6).
• Do not use this code if the documentation indicates complications such as ulceration, gangrene, or prolapse with strangulation, as more specific codes exist.
• Ensure the documentation supports the "thrombosed" aspect; simple hemorrhoids without thrombosis would be coded differently.
