ICD-10-CM Code W54.0XXA is a billable diagnosis code used to report the initial medical encounter for injuries caused by a dog bite. Healthcare providers assign this code when a patient receives active treatment after being bitten by a dog, including emergency care, physician evaluation, wound management, or surgical treatment.
The code is recognized for medical billing, insurance reimbursement, clinical documentation, and healthcare reporting across hospitals, urgent care centers, emergency departments, and physician practices.
