Summers are a pleasant time to enjoy and engage in fun-filled activities outdoors. However, the rise in temperatures brings with it certain inconveniences like sunburn, dehydration, and uninvited guests like mosquitoes and ticks.
A recent report by the New York Times tells us that in recent years, bug bites from mosquitoes, ticks, and fleas have increased drastically in the United States. In this blog, we will talk about ICD-10 Codes for Tick Removal.
Ticks are tiny, pesky, blood-sucking parasites known to carry Lyme Disease. Unlike mosquitoes and other bugs, parents and adults don’t try to handle tick bites on their own. It requires a professional to remove it to ensure no part of the tick remains attached to the skin.
The treatment involves:
- Tick extraction
- Tick bite treatment
- Removal of tick
- Extraction of foreign body – tick
- Insect bite treatment
ICD-10 Codes for Tick Removal
Pediatric coders see a rise in tick bites and tick-borne illnesses in the summertime. There are specific ICD-10 codes to classify this procedure for billing, statistical, and record-keeping purposes. It is crucial to use accurate ICD-10 codes for treating tick bites.
The correct code usage indicates the bite, complications like Lyme disease, and whether the tick removal process was easy, complex, or complicated. It is important to use the exact ICD-10 code for every encounter to ensure correct claim creation and full payment reimbursement.
To simplify things for you, we’ve listed standard tick removal ICD-10 codes for multiple situations in the next section.

A69.21: Meningitis due to Lyme disease
Symptomatic Codes (prior to Lyme disease diagnosis)
R21: Rash and nonspecific skin eruption
R50.9: Fever, unspecified
An Overview of Tick Bite Coding
When coding for tick bites, healthcare providers, medical billers, and coders need to be extremely careful. Some inexperienced coders think that doing so just involves mentioning a simple code. In reality, it is much more complicated than it seems.
Coding for tick bites necessitates two diagnosis codes for correct charge capture, contrary to other insect bites. Initially, you must pick a specific code to report the injury and its location. This is done to show the exact location of the tick bite in medical records, i.e., arm, leg, or any other body part.
To follow it up, use a second code from the external cause chapter to mention how the injury happened. Assigning the second code helps to add context, such as showing the cause of the injury, i.e., tick bite.
Tick Removal Billing Using Appropriate ICD-10 Codes
The claim creation of tick removal is based on the complexity of the removal/treatment process. Here’s a detailed guide on how to do it using ICD-10 codes.
Nature of The Removal
When the doctor or healthcare provider uses a simple tool like tweezers to remove the tick, the scenario requires using an Evaluation and Management (E/M) code, 99212. If the doctor deems an incision or any complicated procedure is necessary, the person coding the incident must use 10120 and 10121.
The situations these codes represent are: Incision and removal of a foreign body, subcutaneous tissue, simple and complicated, respectively.
Using Precise Diagnosis Codes
Medical billing coders must be very careful when selecting the diagnosis codes to represent the explicit location and to indicate the cause. A tiny mistake can lead to claim denial and withholding of payment from the payor.
It is essential to start by mentioning the code for the location of the injury or bite. For instance, S00.06XA indicates a bite on the head scalp. Then, use an external cause code to show the reason, like W57.XXXA for being bitten by a nonvenomous insect.
Adding Accurate Details for A Correct Bill
Now, this is the tricky part which confuses many providers and billers. They miss crucial details and forget to mention and use the correct ICD-10 codes for each item like specific procedure, location and time spent and other intricacies.
Accurate details in medical records demand close attention to detail. For a bill to get through and pass without any objections, it is pertinent to include thorough documentation of the procedure used, time taken for treatment, symptoms, and complications to support the ICD-10 codes.
Billable ICD-10 Code for Tick Bite
W57.XXXA is the billable code for a tick bite in the 10th revision of the International Classification of Diseases. In the medical world, this 7-digit numeral is used to represent the initial encounter with the nonvenomous bite or sting by an insect or any other nonvenomous arthropod.
It is important to note that if the initial encounter is subsequent or for a sequela, the coder will use:
- W57.XXXD for a subsequent encounter
- W57.XXXS for sequela
Sequela is a medical condition that represents a previous illness, injury, or medical intervention.
Is It Right to Submit W57.XXXA in The Start?
Nope, that would be wrong and could lead to consequences like insurance claims denial. Many coders and healthcare providers do the same by placing the external cause code, i.e., W57.XXXA in the start.
Although this billable code represents a bite or sting by a venomous insect (like a tick), submitting it in the first position would be a grave mistake. W57.XXXA, being an external cause code, specifically informs about the context of the injury, like how it occurred.
Also, these are supplementary codes and only inform regarding the external circumstances of the injury instead of detailing the complete injury. ICD-10 guidelines also decree that an external cause code shouldn’t be the primary code on a bill.
So, to show a tick bite on a claim form, the primary code will be used to indicate the nature and location of the injury. For correct billing, it is crucial to place the ‘S’ code at the start to address the condition from the tick bite.
Common Examples for Billing ICD-10 Codes for Tick Removal
In this section, we’re going to discuss some of the common billing scenarios for tick removal to make it easy for you to understand.
1. Simple Tick Removal
The situation involves a patient visiting a facility for an uncomplicated procedure. The healthcare provider will simply extract the tick using tweezers. The entire process is short-lived and takes around 10-15 minutes. They’ll use 99212 for a simple outpatient visit with no complications.
The patient could be suffering from mild fever, headache, and skin rash in the area. The provider will locate a dark spot on the affected area to perform the procedure. Also, tick removal with tweezers doesn’t require any code.
Coding and Billing for Simple Tick Removal
The documentation will be like this – a patient visits with a tick on the scalp. After examining it, the provider removes it using tweezers. They’ll mention (E/M) code 99212 for a simple visit. The diagnosis codes used will be S00.06XA and W57.XXXA to indicate nonvenomous insect bite.
2. Complicated Removal
The scenario involves a patient visiting a medical facility for a complicated procedure for tick removal. The tick’s head is inside the patient’s skin and may require around 40 minutes to complete the procedure. They’ll use 99213 for a detailed E/M service.
For accurate payment, the provider will record and mention the exact time for the procedure. In case the procedure doesn’t involve testing, provider will only charge for the tick removal just like the first scenario.
Coding and Billing for Tick Removal (complicated)
The documentation will be like this – a patient visits with a tick deeply embedded in the scalp. Removal of the tick requires more time and effort. They’ll mention (E/M) code 99212 for a detailed visit. The diagnosis codes used will be S00.06XA and W57.XXXA to indicate nonvenomous insect bite.
3. Tick Removal with Incision
This is the most complicated scenario, as the tick is deeply embedded in the patient’s skin and requires an incision to detach it from the skin.
In the bill, they’ll mention 10120 (simple) or 10121 (complicated) codes pointing towards incision to remove a foreign body. The medical specialist will use the # 11 blade to make an incision for tick removal.
Coding and Billing for Tick Removal Using an Incision
The documentation will be like this – a patient visits with a deeply embedded tick. An incision is required to remove the foreign body.
The mentioned procedure codes will be 10120 or 10121 for simple or complicated incisions and foreign body removal. The diagnosis codes used will be S00.06XA and W57.XXXA to indicate nonvenomous insect bite.
Guidelines for Tick Removal Billing and Coding
If you are a healthcare provider, in-house staff working for a healthcare facility, or someone employed in a third-party medical billing company, below are some fantastic tips to practice while coding for tick removal services.
Following these helpful tips will guarantee compliant billing and swift revenue collection.
1. Always Use Two Codes
While coding for tick bites, the providers, billing staff, or third-party RCM providers should always use two codes. One is to specify the injury, such as the affected area of the body, and the other for external cause, i.e., the tick itself.
For instance, if a patient visits your facility after a tick bite on the scalp, the correct way to code the procedure and treatment will be by using S00.06XA for the tick bite and W57.XXXA to indicate nonvenomous insect bite.
2. Ensure Proper Documentation
Always remember to document the exact details and time spent during the procedure. Include complete information like the tick removal method, complications, and symptoms faced by the patient. For instance, if you removed the tick from a child’s body and it took 15 minutes to complete the process, document all details and record time to justify billing an E/M code 99212.
3. Stay Current with Updates
Remember that coding implementation and rules can change. To ensure compliance and accuracy, it is necessary for healthcare providers to stay updated with the latest coding updates and guidelines from sources like AAPC and CMS.
For instance, if CMS brings in a new code for tick-related ailments or makes changes to them, you need to be aware of the changes.
4. Differentiate Between Removals
When selecting between simple and complicated tick removal methods, you need to differentiate the codes as well. For instance, removing a tick using a tweezer only requires an E/M code. On the contrary, if the situation is complicated and requires an incision, the provider will use 10120 for simple procedures and 10121 for complex processes.
5. Consider Lyme Disease Diagnosis
If a patient visiting your practice or facility is suffering from Lyme disease symptoms like rashes, fever, headache or fatigue, ensure that you include the code for Lyme disease (A69.2). Before diagnosis and confirmation, you may mention codes only for symptoms like R50.9 for fever and R21 for rash.
6. Mention Accurate External Cause Code
When coding for tick bites, providers need to use the correct external cause code – W57.XXXA. This ICD-10 code indicates the cause of injury and is essential for billing. For example, if a patient reports a tick bite, you must include the injury location and external cause.
7. Code for Specific Locations
If a patient is suffering from more than one tick bites on different body parts, the provider should assign different codes for every location. For instance, if a patient has tick bites on the scalp, on the left thigh, or on the neck, the codes to use here are S00.06XA, S70.362A, and S00.469A, respectively.
8. Avoid Upcoding
Healthcare providers must not upcode for treatment procedures not provided. This malpractice can lead to penalties. For instance, if a patient visits your facility after removing the tick at home, avoid coding for a tick removal procedure. Instead, use an E/M code to refer to their visit.
Only bill for the evaluation if they’ve come for a follow-up after removing the tick at home.
9. Understand ICD-10 Classification for Insect Bites
The tenth revision of the International Classification of Diseases, Clinical Modification, has various chapters representing different diseases and conditions. The 19th chapter classifies insect bites like injury caused, poisoning, and other consequences of external causes.
Therefore, providers are advised to use the accurate code starting with an ‘S’ to refer to the injury location and the W57 code representing the external cause. Here’s an example to make it easy for you. If a person has a tick bite on their neck, the bill must have S10.16XA to specify the location and W57.XXXA for an external cause.
10. Keep Your Staff Updated
Now, this is one of the most significant aspects of billing, documentation and getting reimbursed. This is why it is important for healthcare providers to educate their billing team regarding accurate documentation and coding for tick removal and other conditions like insect bites, etc.
Industry experts suggest continuous training to stay updated with the coding guidelines and conducting sessions on ICD-10-CM codes for correct documentation and coding for record keeping and reimbursements.
ICD-10 Coding Structure for Insect-Related Injuries
Now you’re aware of the complexities involved in coding for tick removal, how to document and create accurate bills for tick removal treatment, which is the billable code, and much more.
Let’s move on to the ICD-10 codes required to document insect bites on different body parts ranging from thorax to arms and head to abdomen. Going through this section will give you a clear picture of how to code for insect bites and maintain error-free records.
Thorax
There are different ICD-10 codes for thorax depending on the location of the bite, i.e., front or back wall of the thorax. These codes allow the provider to specify the exact location of the bite, like the front or back wall of the thorax, which enhances the accuracy.
Codes for the Front Wall of Thorax
S20.361: Represents a nonvenomous insect bite of the right front wall
S20.362: Represents a nonvenomous insect bite of the left front wall
