About coding chronic endometritis
The ICD-10-CM code for chronic endometritis is N71.1 (Chronic inflammatory disease of uterus).
Within N71 (inflammatory disease of uterus, except cervix), N71.1 is specifically for chronic inflammatory disease of uterus. Related codes cover acute inflammatory disease of uterus (N71.0) and inflammatory disease of uterus, unspecified (N71.9).
Use an additional code (B95-B97), to identify infectious agent.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
