Internal thrombosed hemorrhoids

This code describes a condition where an internal hemorrhoid has developed a blood clot within it, leading to acute pain and swelling. Internal hemorrhoids originate above the dentate line and are typically covered by mucosa. The thrombosis signifies an acute complication of pre-existing internal hemorrhoidal disease.

Use this code when documentation clearly indicates an internal hemorrhoid that has become thrombosed. This often presents with sudden onset of severe perianal pain, a palpable tender lump, and sometimes bleeding. Physician notes should explicitly state "internal thrombosed hemorrhoid" or describe the clinical findings consistent with this diagnosis.

• Differentiate from external thrombosed hemorrhoids, which are coded differently.
• Ensure the documentation specifies "internal" to avoid confusion with other types of thrombosed hemorrhoids.
• Consider sequencing with other hemorrhoid codes if multiple types or complications are present, prioritizing the most acute or severe condition.
