Code Description

ICD-10 B71.0 is a billable code used to indicate a diagnosis of diphtheria due to corynebacterium diphtheriae.

Key Diagnostic Point:

Diphtheria is an acute bacterial infection caused by the bacterium Corynebacterium diphtheriae. It primarily affects the mucous membranes of the throat and nose, leading to symptoms such as sore throat, fever, and the formation of a thick gray or white coating in the throat. This coating can obstruct breathing and swallowing. Diphtheria is transmitted through respiratory droplets or contact with contaminated surfaces. The disease can lead to serious complications, including myocarditis and neuropathy, if not treated promptly. Vaccination with the diphtheria toxoid is the primary preventive measure, and treatment typically involves the administration of diphtheria antitoxin and antibiotics such as penicillin or erythromycin. Early diagnosis and intervention are crucial to prevent severe outcomes.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires knowledge of specific bacterial infections and their coding.
  • Differentiation from other respiratory infections can be challenging.
  • Documentation must specify the causative organism.
  • Potential for complications requires careful coding.

Audit Risk Factors

  • Inadequate documentation of the causative organism.
  • Failure to document vaccination status.
  • Misclassification of diphtheria as a non-specific respiratory infection.
  • Omission of complications in the coding.
