Ob-Gyn Coding Alert

You have reason to rejoice -- here's why.

Endometriosis is a benign condition in which tissue that looks like endometrial tissue grows in abnormal places in the abdomen. Here's how you report these conditions now:

• 617.0, Endometriosis of the uterus
• 617.1, Endometriosis of the ovary
• 617.2, Endometriosis of the fallopian tube
• 617.3, Endometriosis of pelvic peritoneum
• 617.4, Endometriosis of rectovaginal septum and vagina
• 617.5, Endometriosis of intestine
• 617.8, Endometriosis of other specified sites
• 617.9, Endometriosis site unspecified

Keep in mind: When you use 617.8, you're specifying the endometriosis of the bladder, umbilicus, or vulva.

In 2013, you will find a direct one-to-one correlation between each of these codes. The new code series are:

• N80.0, Endometriosis of uterus
• N80.1, Endometriosis of ovary
• N80.2, Endometriosis of fallopian tube
• N80.3, Endometriosis of pelvic peritoneum
• N80.4, Endometriosis of rectovaginal septum and vagina
• N80.5, Endometriosis of intestine
• N80.8, Other endometriosis
• N80.9, Endometriosis, unspecified

The provider should document where the endometriosis occurs. If the provider documents "Adenomyosis," then you should report N80.0.

Coding Tips: When you look at the N80 series in your manual, you'll see this category is the first listing under "Noninflammatory disorders of female genital tract (N80-N98)."

Underneath N80.0, you'll see an Excludes1 note that says you cannot report N80.0 and stromal endometriosis (D39.0) together on the same claim.
