About coding parametritis
The ICD-10-CM code for parametritis is N73.2 (Unspecified parametritis and pelvic cellulitis). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on N73.2.
Within N73, choose N73.2 (Unspecified parametritis and pelvic cellulitis) only when documentation doesn't support a more specific option: acute parametritis and pelvic cellulitis (N73.0), chronic parametritis and pelvic cellulitis (N73.1), female acute pelvic peritonitis (N73.3), female chronic pelvic peritonitis (N73.4), female pelvic peritonitis, unspecified (N73.5), female pelvic peritoneal adhesions (postinfective) (N73.6), other specified female pelvic inflammatory diseases (N73.8) and female pelvic inflammatory disease, unspecified (N73.9).
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.
