CPT® Code 49566

Deleted

A recurrent incisional or ventral hernia repair involves the surgical correction of a hernia that has reappeared at the site of a previous abdominal incision. An incisional hernia, also known as a ventral hernia, occurs when the abdominal wall does not heal properly after surgery, leading to a separation of tissues at the incision site. This separation allows abdominal organs to protrude through the weakened area, creating a bulge. The complexity of repairing a recurrent hernia can vary significantly based on the size of the defect and the degree of scarring and tissue damage from the initial surgical repair. In cases where the hernia is reducible, meaning the contents can be pushed back into the abdomen, a different code (CPT® 49565) is used. However, for recurrent hernias that are incarcerated or strangulated, CPT® code 49566 is applicable. An incarcerated hernia is one where the contents cannot be returned to their normal position, while a strangulated hernia indicates that the blood supply to the herniated tissue is compromised, necessitating urgent surgical intervention. The surgical procedure typically involves excising the old scar, dissecting the hernia sac, and repairing the abdominal wall, which may include techniques such as suturing or the use of mesh for larger defects.
