What This Code Means
N86 is the ICD-10-CM diagnosis code for erosion and ectropion of cervix uteri. Damage or turning outward of the cervical tissue, often causing irritation, bleeding, or discharge. N86 sits in the ICD-10-CM chapter for diseases of the genitourinary system (n00-n99), within the section covering noninflammatory disorders of female genital tract (n80-n98).
N86 is a billable ICD-10-CM code, but no current CMS-HCC V28 community payment mapping is shown, and none under the ESRD, Part D RxHCC, or HHS-HCC models. Do not assign risk adjustment value from this page when no source-backed mapping is shown; verify the applicable model and payment year.
Document whether this is erosion (loss of surface tissue) or ectropion (eversion of tissue) as they may have different etiologies.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for N86 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Document whether this is erosion (loss of surface tissue) or ectropion (eversion of tissue) as they may have different etiologies
- •Note any associated symptoms such as postcoital bleeding or abnormal discharge for complete clinical documentation
