Code Description

ICD-10 N71.9 is a billable code used to indicate a diagnosis of inflammatory disease of uterus, unspecified.

Key Diagnostic Point:

Inflammatory disease of the uterus encompasses a range of conditions affecting the female reproductive system, primarily involving the uterus, fallopian tubes, and ovaries. This code is used when the specific type of inflammatory disease is not specified. Common conditions associated with this code include salpingitis (inflammation of the fallopian tubes), oophoritis (inflammation of the ovaries), pelvic inflammatory disease (PID), endometritis (inflammation of the endometrium), and cervicitis (inflammation of the cervix). Symptoms may include pelvic pain, abnormal vaginal discharge, fever, and dyspareunia. Diagnosis typically involves a combination of clinical evaluation, imaging studies, and laboratory tests. Treatment often includes antibiotics to address the underlying infection, and in some cases, surgical intervention may be necessary. Accurate coding is crucial for appropriate treatment and reimbursement, as well as for tracking the incidence of these conditions in the population.

  • Potential for multiple concurrent diagnoses

Audit Risk Factors

  • Insufficient documentation of symptoms and diagnosis
  • Failure to specify the type of inflammatory disease
  • Inconsistent coding of concurrent conditions
  • Lack of clarity in treatment plans

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for greater specificity in coding inflammatory diseases, but it also requires coders to be more diligent in documenting the specifics of each case to avoid ambiguity.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for greater specificity in coding inflammatory diseases, but it also requires coders to be more diligent in documenting the specifics of each case to avoid ambiguity.
