Gynecology-related diagnostic codes
Laterality
If there are 2 organs in the genitourinary system, the chances are good that there is now a right and a left designation code in ICD-10. Documentation should be clear, of course, and if the condition exists on both the right and the left side (even if only one side is being treated actively), list both codes, as there is no bilateral designation in the codes (TABLE 3). And while there is a code for “unspecified side,” providers normally do know which side, so use of this code should be avoided, if possible.
Vaginal septum
The right and left designations extend to the congenital codes for vaginal septum, but they go one step further. The American Congress of Obstetricians and Gynecologists (ACOG) requested that the codes for longitudinal vaginal septum be expanded to differentiate a nonobstructing vaginal septum from an obstructing vaginal septum, in addition to adding laterality to these codes (TABLE 3).2
Mastitis
There are now 2 new codes for inflammation of the breast; one describes mastitis without abscess, while the other code includes an abscess of the breast and nipple (TABLE 4). Once again, documentation will lead to the most specific code to describe the findings.
Childhood and prepubertal concerns
The single code for hypertrophy of the vulva has been expanded to include asymmetric labium majus enlargement. This code was requested by ACOG because this is a known clinical diagnosis and the currently available vulvar codes are inadequate for capturing this condition. The vulvar enlargement appears to be in response to hormonal surges during prepuberty and early puberty. Adult hypertrophy, either congenital or acquired from childbirth or as a late result of an old injury, would be reported by the “other specified” code (TABLE 5).
The causes of prepubertal bleeding vary and include the presence of a foreign object, tumors, or fluctuations in hormones, but prepubertal bleeding differs from the bleeding associated with normal menstruation. For that reason, ACOG requested a code that better captures the nature of the condition before a thorough work-up has pinpointed the cause (TABLE 5). Once the cause of the bleeding is known, a more specific diagnosis would then be reported (eg, D28.1, Benign neoplasm of vagina, or T19.2XXA, Foreign body in vulva and vagina, initial encounter).
Dypareunia
Additional documentation for dyspareunia will now be required to ensure that the most specific code is reported. In this case, the clinician should identify whether the pain is superficial or deep to better report on female pelvic floor dysfunction and to support the different treatments based on the location of the pain (TABLE 6). Deep dyspareunia would be felt in the mid or upper vagina.
