Which code for Gartner’s duct cyst procedure?

Author and Disclosure Information


Q What CPT code should I use for marsupialization of Gartner’s duct cyst?

A If the cyst was excised, code 57135 (excision of vaginal cyst or tumor), is appropriate.

But if it was a marsupialization procedure in which the cyst was drained first and then the walls of the cyst were sewn in place to form a pouch, then the procedure should be coded using the unlisted code, 58999 (unlisted procedure, female genital system [nonobstetrical]).

The Gartner’s duct is usually located in the lateral wall of the vagina, so the code to report marsupialization of a Bartholin gland cyst, 56440, would not apply.

Be sure to let the payer know that the procedure is very similar to the 2 codes 56440 (Bartholin’s) and 57135 (excision). Code 56440 has 4.89 RVUs, while 57135 has 5.25 RVUs.
