A27.89

What This Code Means

This code represents uncommon or atypical forms of leptospirosis, a bacterial infection transmitted through contact with infected animal urine, typically from rodents or other wildlife. It is used when the leptospirosis does not fit into the more common clinical presentations like Weil's disease or aseptic meningitis.

Coding Tips

• •Use this code only after excluding the more specific leptospirosis subtypes (A27.0 through A27.81), as it is a residual category for other manifestations
• •Ensure documentation clearly describes the atypical presentation or organ system involved, as this helps justify the use of the 'other forms' code rather than a more specific subtype
