What This Code Means
N71 is the ICD-10-CM diagnosis code for inflammatory disease of uterus, except cervix. N71 sits in the ICD-10-CM chapter for diseases of the genitourinary system (n00-n99), within the section covering inflammatory diseases of female pelvic organs (n70-n77).
Header codes like N71 cannot be reported on claims directly; they organize child codes that share clinical context. Coders should select the billable child code that matches the documented presentation and then verify its current source-backed HCC mapping. Do not infer a child code or risk adjustment value from the header alone.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for N71 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Includes
- endo (myo) metritis
- metritis
- myometritis
- pyometra
- uterine abscess
