About coding cervix patent
The ICD-10-CM code for cervix patent is N88.3 (Incompetence of cervix uteri).
Within N88 (other noninflammatory disorders of cervix uteri), N88.3 is specifically for incompetence of cervix uteri. Related codes cover leukoplakia of cervix uteri (N88.0), old laceration of cervix uteri (N88.1), stricture and stenosis of cervix uteri (N88.2), hypertrophic elongation of cervix uteri (N88.4), other specified noninflammatory disorders of cervix uteri (N88.8) and noninflammatory disorder of cervix uteri, unspecified (N88.9).
Don't report N88.3 together with the conditions in its Excludes1 note: cervical incompetence complicating pregnancy (O34.3-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for N88.3)
- cervical incompetence complicating pregnancy (O34.3-)
