Coding Tips

• •Use this unspecified code only when the documentation does not indicate whether the infection is in the urethra, prostate, or other urogenital sites; if location is documented, use the more specific subcategories (A59.01, A59.02, A59.03)
• •Verify if the patient is male or female and review documentation for any site-specific symptoms, as this may allow for a more specific code assignment
