Bitten by a cat? You better rush to your nearest clinic. During the encounter, the doctor will append the code W55.01XA to show a cat bite on the claim.
However, only mentioning the cause of the injury may not be enough to fulfill the health insurance guidelines. The healthcare provider must also mention the specific injury.
Why Is It Necessary? According to the submission rules, the actual injury must be reported first. It clarifies to the insurance company whether it was a laceration requiring stitches, a contusion causing swelling, or a sprain requiring bracing.
ICD-10 Code for Cat Bite Injury
When a patient visits a clinic or hospital after a cat bite, the doctor indicates the initial encounter using W55.01XA. Although this ICD-10 code used for cat bite specifies the exact cause of injury, however, it doesn’t clarify the type of injury suffered after the bite.
Let’s make it simple for you. Suppose the cat bit the patient on the right hand and they’re suffering from an infected puncture, healthcare specialists will append S61.451A with W55.01XA. This specific ICD-10 code stands for open bite of the right hand, initial encounter after the cat bite as an external cause.
This way, ‘Bitten by a Cat’ – which is not a valid diagnosis can be turned into a valid diagnosis. Only mentioning W55.01XA will not suffice to describe the severity or the exact injury caused, and hence, it will remain an invalid diagnosis.
“Bitten by A Cat” Is A Valid ICD-10 Diagnosis Code or Not
Writing only the code W55.01XA on the claim only specifies the external injury cause and doesn’t constitute a complete ICD-10 diagnosis. Why are we emphasizing it? Because coders require a complete picture of the injury and just by mentioning the ICD-Code for a cat bite, there isn’t any specificity needed for a full medical diagnosis.
They cannot assign a principal diagnosis as it may result in complications in the claims, leading to denials and loss of revenue. Moreover, the medical documentation will not be trustworthy, and the doctor cannot devise the proper action to treat the patient.
W55.01XA: Is It an External Cause or A Fully Diagnostic Code?
W55.01XA is considered an external cause code only. Present in chapter 20 of the tenth revision of the International Classification of Diseases, these codes only show the cause of the injury. They only describe the context. However, they do not precisely state the type or severity of the wound/injury.
Simply saying, W55.01XA does clarify that the wound or injury resulted from a cat bite. However, it doesn’t explain the condition of the injury, like a fracture or a laceration.
Converting W55.01XA into A Valid Diagnostic Code
Now, you know that “W55.01XA Bitten by a cat bite” isn’t a valid diagnostic code. It is just an external cause. And to make it complete or valid, it must be appended with a code describing the nature and severity of the injury.
When a cat bites a patient, and they suffer a fracture of the left tibia, the medical coder will report S82.202A in the claim form. In the medical world, S82.202A describes a “fracture of left tibia, initial encounter.” Attaching W55.01XA with S82.202A means your claim clearly pictures the cause of the injury and the exact injury.
Adherence to Coding Guidelines
This is the most essential part of claim creation and documenting the correct condition for medical and reimbursement purposes. Healthcare providers or medical coders must be aware of how to use the external cause, i.e., W55.01XA, in conjunction with the diagnostic code, i.e., S82.202A to explain the condition of the patient.
The same goes for combining S91.331A as an external cause code along with W55.01XA to show the cat bite resulted in a puncture wound. Only this way can you describe the injury thoroughly, which not only leads to accurate medical diagnosis and treatment but also proper reimbursement against claims.
Applying Cat Bite ICD-10 Codes for Multiple Areas
When a person visits your practice or clinic after a cat bite, the healthcare provider, medical biller, or anyone responsible for claim creation and documentation must use a precise ICD-10 code that perfectly describes the area affected, i.e., the location where the cat bit and the wound is created.
This way, you’re ensuring accurate diagnosis, which will automatically lead to claim approval without any obstacles. Every specific code describes the exact body part and nature of the injury caused. Hence, the correct code usage means flawless documentation and the right treatment procedure.
Let’s take you through some specific location codes – that are used with cat bite ICD-10 codes – serving as external cause codes.
S61.451A: ICD-10 Code for Cat Bite on Right Hand
This code is normally used to describe a bite wound injury on the patient’s right hand. For correct diagnosis and treatment planning, the injury type is specified as open bite.
S61.452A: ICD-10 Code for Cat Bite on Left Hand
S61.452A is used to document an open bite injury on the patient’s left hand. Using this code helps healthcare providers to identify and classify the type and severity of the injury.
S51.851A: ICD-10 Code Representing Cat Bite on Right Forearm
If the patient suffers from a cat bite injury on the right forearm, medical coders use S51.851A to report the exact patient encounter. It helps to specify a bite injury.
S51.852A: ICD-10 Code Showing Cat Bite On Left Forearm
If the patient suffers from an open bite on the left forearm, the healthcare providers will use S51.852A to document the encounter. This helps specialists gain correct info about the type and location of injury.

The Need for Accurate Documentation
Proper and quick diagnosis and the right treatment for cat bites emphasize the fact that documentation should be carefully carried out, and it must be free from errors. However, like any other field, documentation in the healthcare industry is vulnerable to mistakes.
These coding or other errors in documentation can lead to serious treatment debacles and reimbursement issues. The ability to identify and rectify these errors comes with a lot of advantages.

External Cause Codes Only

Wrong Injury Location Code
Not specifying the correct location or the injured body part means wrong claims creation. Insurance companies are very strict when it comes to denying claims with incorrect coding.
Excluding Specific Injury Codes
Not paying attention to detail or failing to include precise codes that describe the type and nature of injury can be costly. Ensure you include correct injury codes representing lacerations, swelling, and fractures. Otherwise, your claims will be disapproved.
Not Updating Codes
Another reason for claim denials and inaccurate diagnoses is not updating codes according to the updated ICD-10 revisions. Using old and incorrect codes will lead to rejections and compliance issues.
If you pay close attention to details and are acquainted with the updated codes and usage guidelines, you can avoid serious mistakes.
An error-free billing cycle is paramount for your practice’s performance and productivity. Apart from correct billing and collecting the full amount against services, errors-free documentation also ensures that the patient receives high-quality, focused, and correct treatment as early as possible.
