What is the icd 9 code for a ileostomy reversal?

The ICD-9 code for ileostomy reversal is 45.73, which specifically refers to "Closure of ileostomy." This code is used when documenting the surgical procedure of reversing an ileostomy, restoring the normal function of the digestive tract. It's important to note that ICD-9 has been largely replaced by ICD-10, so it's advisable to verify the current coding standards for accurate billing and documentation.
