Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to N77: its own notes plus those printed at block N70-N77 and Chapter 14. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

From Block N70-N77 Inflammatory diseases of female pelvic organs applies to 39 codes
  • inflammatory diseases of female pelvic organs complicating:
  • abortion or ectopic or molar pregnancy (O00-O07, O08.0)
  • pregnancy, childbirth and the puerperium (O23.-, O75.3, O85, O86.-)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 14 (N00-N99) Diseases of the genitourinary system applies to 838 codes
  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)

  • neoplasms (C00-D49)
  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)

Questions About N77Overview

Is N77 a billable code?

No. This is a category header that groups the codes for vulvovaginal ulceration and inflammation in diseases classified elsewhere, and headers cannot be submitted on claims. Claims for vulvovaginal ulceration and inflammation in diseases classified elsewhere need a more specific code from this category, such as N77.0 and N77.1.

Can N77 be reported with O08.0?

Not as a rule. The Excludes1 note at block N70-N77, which applies to N77, lists "abortion or ectopic or molar pregnancy (O00-O07, O08.0)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
