Ob-Gyn Coding Alert

Your 620 codes become N83 ones in 2013.

An ovarian cyst consists of a fluid filled closed sac or cavity in the ovary. The cyst is usually lined by epithelium. They can be normal, abnormal, non-neoplastic, or neoplastic tissues.

Here's how you report these codes right now:

• 620.0 -- Follicular cyst of ovary
• 620.1 -- Corpus luteum cyst or hematoma
• 620.2 -- Other and unspecified ovarian cyst.

When your diagnosis coding system changes in 2013, you'll report ovarian cysts like this:

• N83.0 -- Follicular cyst of ovary
• N83.1 -- Corpus luteum cyst
• N83.20 -- Unspecified ovarian cysts
• N83.29 -- Other ovarian cysts

ICD-10-CM Change: For a follicular cyst of ovary and the corpus luteum cyst, you have a direct one-to-one match. However, your other and unspecified ovarian cyst code expands into two different options.

Documentation: The provider may document many different terms to describe ovarian cyst. Underneath N83.0, you'll see terms "cyst of graafian follicle" and "hemorrhagic follicular cyst (of ovary)." Underneath N83.1, you'll see the term "hemorrhagic corpus luteum cyst." Finally, underneath N83.29, you'll find the terms "retention cyst of ovary" and "simple cyst of ovary."

Coding tips: You'll find these codes under the N83 category, entitled "Noninflammatory disorders of ovary, fallopian tube and broad ligament." Underneath this title, an Excludes 2 note says it's not likely that you'll report hydrosalpinx codes (N70.1-) in addition to the N83 category codes. However, you can still report these codes together, should your physician document both conditions.

Underneath the N83.2- codes, you'll see an Excludes1 note saying you should never report N83.20 and N83.29 with developmental ovarian cyst (Q50.1), neoplastic ovarian cyst (D27-), polycystic ovarian syndrome (E28.2), or Stein-Leventhal syndrome (E28.2). An Excludes1 note means you will never report these conditions together.
