K61: Abscess of anal and rectal regions
The ICD-10 code K61 refers to a group of conditions that involve an abscess, or a pocket of pus, in the anal and rectal regions. Abscesses are often caused by blocked glands or small tears in the tissue that result in infection. This infection generates pus and inflammation, leading to discomfort, pain, redness, and swelling in the affected area. Common symptoms include pain when sitting or moving, fever, and constipation. Occasionally, an abscess can cause the skin to 'point' or bulge where pus is trying to come out. These abscesses can develop rapidly and may require immediate medical care. If untreated, these abscesses may lead to more serious complications such as a full body infection or the infection spreading to surrounding tissue.
