T80-T88: Complications of surgical and medical care, not elsewhere classified

The group of conditions categorized as "Complications of surgical and medical care, not elsewhere classified" consists of a broad range of health issues that can occur during or after medical intervention. These complications may arise from various medical procedures, surgeries, or treatments and are not associated with other specified conditions. For instance, a patient might have an unexpected reaction to anesthesia, an infection following a surgical procedure, accidental cuts or punctures during medical care, or a post-operative blood clot. Symptoms can fluctuate greatly depending on the type and severity of the complication, but common ones may include redness, swelling, fever, pain, or changes in the body function related to the treatment area. The progression of these complications can be swift or slow, and multiple body systems may be affected. Not all complications are preventable, and they can occur even with high-quality medical care.
