Billable code

Isthmocele

The ICD-10 code for isthmocele is N85.A.

Clinical notes

Code also

Two codes may be needed to fully describe a condition, but unlike Code First/Use Additional Code, the sequencing order is not mandated by convention.

  • any associated conditions such as:
  • abnormal uterine and vaginal bleeding, unspecified (N93.9)
  • female infertility of uterine origin (N97.2)
  • pelvic and perineal pain (R10.2-)

Excludes1 (not coded here)

An Excludes1 note is a pure exclusion: the excluded condition and this code should never be reported together, because the two conditions cannot occur at the same time (e.g. a congenital form vs. an acquired form of the same disease).

  • maternal care for cesarean scar defect (isthmocele) (O34.22)
