While reviewing a patient’s chart after treating them for tick bite, you have to enter the ICD-10 codes, but you take a pause to decide. This is where most medical professionals face difficulties. Was the tick venomous or non-venomous. Where exactly does the bite exist? Every single one of those parameters requires a different code which increases the complexity. Getting any one of these things wrong can lead to denial of your claims.
This is why getting it done by professionals is important. In this blog we will learn about all the codes related to ICD 10 tick bite. When everything is in place you will be able to select the accurate tick bite ICD 10 code. This will ensure a smooth billing process and proper documentation every time.
How Is a Tick Bite Coded?
While coding for tick bite, it is not as easy as simply selecting a straightforward code. Unlike other insect bites, coding for a tick bite needs two separate diagnosis codes to accurately record the event.
First you need to select a code from the injury chapter that describes the injury and its location. This makes sure that the medical record precisely reflects the accurate site of the tick bite, for e.g.: arms, legs or any other part of the body.
However, this is not it!
You also need to assign a second code from the external cause chapter that transcripts how the injury occurred. This code gives context indicating that a tick bite has caused the injury.
What is the Billable ICD 10 Code for Tick Bite?
The billable ICD-10 code for a tick bite is W57.XXXA. This code represents “bitten or stung non-venomous insects or other non-venomous arthropods, initial encounter.”
If the encounter is subsequent or for a sequela, you must use
- W57.XXXD for a subsequent encounter
- W57.XXXS for sequela
Can you Submit W57.XXXA in the First Position?
A common error made by many healthcare providers is to place the external cause code W57.XXXA in the first position. While W57.XXXA accurately describes being bitten or stung by a non-venomous insect. It should never be submitted in the first position.
External cause codes like W57.XXXA are used to provide additional context about the injury; majorly about how it happened. However, these codes are supplementary. They describe the external circumstances of the injury but do not represent the injury itself. That is why tick bite ICD-10 code mandates that an external cause code cannot be the primary code on the claim form.
To accurately represent a tick bite, your primary code should be described with the injury’s specific nature and location. The “S” code must be placed in the first position on your claim form. This directly addresses the injury or condition resulting from the tick bite. It is essential for accurate billing and documentation.
ICD 10 Code Tree for Insect Bite
Let's take a look into these ICD-10 codes used to document insect bites on any part of the body. We will go through the specific codes that describes the location of the bite, from upper arm to the lower legs. This ensures that you have a clear understanding about how to accurately code for these encounters.
Thorax
While documenting insect bites on the Thorax, the ICD-10 code for tick bites provides specific codes depending on whether the bite is located on the front or back wall of the Thorax.
Front Wall of Thorax
If you need to code for the front wall of Thorax, the ICD 10 code for tick bites can be categorized based on their exact location:
- S20.361: Insect bite (nonvenomous) of the right front wall of the Thorax
- S20.362: Insect bite (nonvenomous) of the left front wall of the Thorax
- S20.363: Insect bite (nonvenomous) of the bilateral front wall of the Thorax
- S20.364: Insect bite (nonvenomous) of the middle front wall of the Thorax
- S20.369: Insect bite (nonvenomous) f the unspecified front wall of the Thorax
These codes help you to specify the precise location of the tick bite on the front wall of thorax which improves the accuracy of your records.
Back Wall of Thorax
For tick bites on the back wall of the Thorax, the codes vary on the basis of location just like the front wall of Thorax
- S20.461: Insect bite (nonvenomous) of the right back wall of the Thorax
- S20.462: Insect bite (nonvenomous) of the left back wall of the Thorax
- S20.469: Insect bite (nonvenomous) of the unspecified back wall of the Thorax
These codes make sure that you can precisely record the area of insect bite on the back wall of the thorax. Whether it is on the right, left, or any unspecified location of the Thorax.
Head
Now let’s learn about documenting insect bites that occur on the head, specifically to the scalp. The ICD-10 code S00.06 describes nonvenomous insect bite in this area. Determining by the type of encounter, here are some specific codes that you should use.
- S00.06XA: Insect bite (nonvenomous) of scalp, initial encounter
- S00.06XD: Insect bite (nonvenomous) of scalp, subsequent encounter
- S00.06XS: Insect bite (nonvenomous) of scalp, sequela
Nose
While documenting an insect bite on the nose, the correct ICD-10 code is S00.36. The code is used to signify nonvenomous insect bites specifically located on the nose. The codes are then specified on the basis of the type of encounter:
- S00.36XA: Insect bite (nonvenomous) of nose, initial encounter
- S00.36XD: Insect bite (nonvenomous) of nose, subsequent encounter
- S00.36XS: Insect bite (nonvenomous) of nose, sequela
Ear
When you are documenting a nonvenomous insect bite on the ear, the ICD code for tick bite is S00.46. This code ensures that the location and nature of injury are accurately reflected in the patient’s medical records.
For different stages of care related to an insect bite on the ear, the codes are modified as follows:
- S00.46XA: This code is used when a patient comes for the initial encounter
- S00.46XD: This code is used for subsequent visits, reflecting ongoing treatment
- S00.46XS: this code is used while documenting a sequela that indicates any lingering effects
Neck
There are specific ICD-10 code for tick bites that reflect a specific affected area. S10.16 is designated for nonvenomous insect bites on the throat. This makes sure that the injury is accurately categorized depending on the location.
Here's how you can use the code in different clinical scenarios:
- S10.16XA: This code is used for the initial medical encounter which documents the first
- S10.16XD: This code is used for taking follow-ups if the patient returns for further treatment
- S10.16XS: This code is used when you are dealing with sequela, which indicates any ongoing issues or complications arising from initial insect bite.
Abdomen, Lower Back, Pelvis, and External Genitals
While documenting nonvenomous tick bites in these areas the ICD 10 codes S30.86 and its subcategories are used. It provides detailed options based on the specific location of the bite. Let's understand the codes in detail:
- S30.860: This code is used for insect bites on the lower back and pelvis that captures the injury in these specific locations
- S30.861: This ICD 10 tick bite code is used if the injury is located on the abdominal wall
- S30.862: This tick bite ICD 10 code is used if the insect bites on the private parts of male
- S30.863: This code specifies that the injury is on the scrotum and testes which ensures that a specific external male genital area is documented.
- S30.864: If the insect bites on the female private parts such as the vagina or vulva, this code is used
- S30.865: When the insect bite is on any unspecified external genitals of male, this code is used.
- S30.866: This tick bite ICD 10 code is used to specify injury on unspecified external genitals of female patients.
- S30.867: For insect bites on the anus, this code is used to define specificity
Shoulders & Arms
There are various tick bite ICD 10 codes specified for shoulders or upper arms. The wide range of options specify the exact location of this bite. This makes sure that every detail is captured. It mentions every detail whether the bite is on the right or left upper arm.
For tick bites on the shoulder, the coding option includes:
- S40.261: This code is used if the insect bite is on the right shoulder
- S40.262: this code signifies bite on the left shoulder
- S40.263: This code specifies that the bite is on the shoulder, but it is not further specified
When the bite is on the upper arm, the coding options allows for more detailed documentation:
- S40.861: This code is used for insect bites on the upper right arm
- S40.862: This code specifies tick bite on the left upper arm
- S40.869: This code is used if the upper arm is unspecified
