The correct CPT® coding for the hernia repair in this case is 49501, 15778.
Explanation for each option:
49496: This code is for laparoscopic repair of an inguinal hernia, which does not match the description of the procedure performed. The procedure described was an open repair, not laparoscopic.
49496, 15778: As mentioned, 49496 is for laparoscopic repair, which is incorrect for this case. However, 15778 is for implantation of mesh or other prosthesis for hernia repair, which is relevant but not sufficient alone.
49495: This code is for open repair of an initial inguinal hernia in patients age 5 years or older, which could be relevant, but it does not specify the complexity of the repair involving a strangulated hernia.
49501, 15778: 49501 is the correct code for open repair of a recurrent inguinal hernia, which is more appropriate given the complexity described (strangulated hernia). Additionally, 15778 is for the use of mesh, which was used in the procedure.
In summary, the correct coding for the procedure described, which involved open repair of a strangulated inguinal hernia with mesh implantation, is 49501, 15778.
