ICD-10 code for endometritis
From the official ICD-10-CM alphabetic index entry “Endometritis (decidual) (nonspecific) (purulent) (senile) (atrophic) (suppurative)”. Page updated September 29, 2026.
About coding endometritis
The ICD-10-CM code for endometritis is N71.9 (Inflammatory disease of uterus, unspecified). The official index lists 13 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on N71.9.
Within N71, choose N71.9 (Inflammatory disease of uterus, unspecified) only when documentation doesn't support a more specific option: acute inflammatory disease of uterus (N71.0) and chronic inflammatory disease of uterus (N71.1).
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.
