A rash similar to the rash of Lyme disease has been described in humans following bites of the lone star tick, Amblyomma americanum. The rash may be accompanied by fatigue, fever, headache, muscle and joint pains. This condition has been named southern tick-associated rash illness (STARI). The cause of STARI is not known. STARI or Lyme?

In the ICD-10 Index, erythema migrans is linked to A26. 0 for cutaneous erysipeloid which seems to be another specific type of bacterial infection.
The first code should be an S code that describes the location of the bite, such as S70. 362A “Insect bite (nonvenomous), left thigh, initial encounter.”
ICD-10 code A69. 2 for Lyme disease is a medical classification as listed by WHO under the range - Certain infectious and parasitic diseases .
What Causes Erythema Migrans? Erythema Migrans is often the first sign of Lyme disease. Lyme disease is caused by the bacteria Borrelia burgdorferi. The bacteria are transmitted to humans through infected deer ticks.
ICD-9 Code Transition: 780.79 Code R53. 83 is the diagnosis code used for Other Fatigue. It is a condition marked by drowsiness and an unusual lack of energy and mental alertness. It can be caused by many things, including illness, injury, or drugs.

919.4 - Insect bite, nonvenomous, of other, multiple, and unspecified sites, without mention of infection | ICD-10-CM.
Although most cases of Lyme disease can be cured with a 2- to 4-week course of oral antibiotics, patients can sometimes have symptoms of pain, fatigue, or difficulty thinking that lasts for more than 6 months after they finish treatment. This condition is called Post-Treatment Lyme Disease Syndrome (PTLDS).
50 – Pain in Unspecified Joint.
If Lyme Disease Antibody Screen is ≥0.90, then Lyme Disease Antibodies (IgG, IgM), Immunoblot will be performed at an additional charge (CPT code(s): 86617 x2).
This tick was first proposed as a possible vector of disease in 1984, and the illnesses associated with the tick called "Lyme-like disease", but it was not recognized to be distinct from Lyme disease until the late 1990s.
It is spread by tick bites and it was hypothesized that the illness was caused by the bacteria Borrelia lonestari. However, there is insufficient evidence to declare this Borrelia strain as a causative agent.
Symptoms. "Bull's-eye" STARI rash. Diagnosis is based on a circular "bull's-eye" rash at the site of infection called erythema chronicum migrans, which is very similar to that seen in Lyme disease. However, the symptoms of STARI are mild, and resemble influenza, with fatigue, muscle pains, and headache. Fever is sometimes seen, but is not ...
It is not to be confused with STAR 1. Lone star ticks can be carriers of southern tick-associated rash illness. Southern tick-associated rash illness ( STARI) is an emerging infectious disease related to Lyme disease that occurs in southeastern and south-central United States.

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code A93.8:
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code (s). The following references for the code A93.8 are found in the index:
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
Viruses are very tiny germs. They are made of genetic material inside of a protein coating. Viruses cause familiar infectious diseases such as the common cold, flu and warts. They also cause severe illnesses such as HIV/AIDS, Ebola, and COVID-19.
The external cause code for the bite cannot be used as a primary diagnosis, and Z11.8 is not correct because the patient is not asymptomatic and this encounter would not meet the definition of a screening.
However you have to go by what best represents what the provider is documenting. Also, I'd just add that a tick is an arthropod and not an insect, so an insect bite code it is technically not correct - if the provider is documenting treating a tick bite, I would use the 'other superficial bite' codes for this.
