ICD-10-CM Code For Other Spirochetal Infections: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group A69 includes infections caused by spirochetes other than those classified under Lyme disease, such as erythema chronicum migrans equivalents and other specified spirochetal diseases, covering localized and systemic presentations. These ICD-10-CM diagnosis codes are used to document clinical encounters for spirochetal infections, capturing disease severity, organ involvement, or clinical complexity relevant to this group. Accurate coding within the ICD-10-CM A69 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

ICD-10-CM A69: Other Spirochetal Infections Overview

The diagnoses in this group represent infections caused by non-lyme spirochetal organisms affecting multiple body systems, commonly presenting with dermatologic, neurologic, or systemic signs. These conditions target infectious disease processes and may involve skin, nervous system, or other organs depending on the pathogen and stage. Accurate coding matters for appropriate clinical documentation and reimbursement because it communicates disease specificity and severity to payers and supports correct claim adjudication.

When to Use

Use a code from this group when a patient has a documented diagnosis of a non-lyme spirochetal infection or a specified clinical syndrome attributed to a spirochete. Assign the code that best reflects the specific organism, site of involvement, and documented clinical manifestations to ensure accurate recordkeeping and billing.

Typical Clinical Scenarios

An adult presents to the emergency department with a several-day history of high fever, severe headache, myalgias, and a diffuse maculopapular rash after recent exposure to wooded areas and tick bite; blood cultures and serology are pending but the clinician documents suspected acute leptospiral infection with systemic involvement, prompting empiric therapy and inpatient monitoring. A diagnosis from this spirochetal group is assigned for the acute systemic zoonotic infection while confirmatory testing is awaited. Typical codes: A69.0, A69.9
A middle-aged patient in outpatient infectious disease follow-up has persistent, intermittent migratory arthralgias, low-grade fever, and fatigue for months after a treated erythema migrans–like illness; evaluation raises concern for chronic manifestations or late sequelae of a spirochetal infection requiring ongoing symptomatic management and specialist assessment. A code from this group is used to capture the chronic/post-infectious spirochetal disease process. Typical codes: A69.21, A69.22
A hospitalized patient with poorly controlled diabetes develops a localized suppurative skin and soft tissue infection at a puncture wound that cultures positive for spirochetes, complicated by cellulitis and requiring surgical debridement; the spirochetal infection is recorded as a comorbidity contributing to the acute complication and treatment plan. A code from this group is applied to document the identified spirochetal pathogen as the cause of the complicated soft tissue infection. Typical codes: A69.23, A69.8
