Candidiasis, often called a yeast infection, is caused by the Candida fungus. Because Candida thrives in warm, moist places, it’s a common cause of infections in the groin area.
When a healthcare professional diagnoses a patient, they use ICD-10-CM codes for billing and record-keeping. Using the right ICD-10 code for candidiasis of groin, among other conditions, is important for proper reimbursement.
This article will focus on the correct ICD-10-CM codes for candidiasis of the groin.
Understanding Candidiasis of the Groin
Causes and Risk Factors
Candidiasis of the groin is most often caused by an overgrowth of Candida albicans, a type of yeast. This yeast is normally present on our skin and inside our bodies, but sometimes, it can multiply and grow out of control, similar to other viruses like HPV.
Several factors can increase your risk of developing candidiasis in the groin area, including:
- Diabetes
- Obesity
- Antibiotic use
- A weakened immune system
- Poor hygiene
- Wearing tight clothing
Symptoms and Diagnosis
The most common symptoms of candidiasis in the groin include:
- Itching
- Redness
- Burning
- Rash
- Small pustules
Doctors usually diagnose candidiasis with a physical exam. They may also take a small skin scraping to look at under a microscope. This can help them confirm the presence of Candida yeast.
ICD-10-CM Code B37.2: Candidiasis of Skin and Nail
ICD-10-CM code B37.2 applies to candidiasis impacting the skin and nails. This includes conditions like candidal onychia (candidiasis of the nail) and candidal paronychia (candidiasis around the nail).
It’s important to choose the correct code because some conditions are specifically excluded from B37.2. The ICD-10-CM uses “Type 2 excludes” notes to show that the excluded condition isn’t actually part of B37.2, but a patient could have both conditions at the same time. For instance, candidiasis of the groin might require a separate code in addition to B37.2, depending on the specific diagnosis.
B37.2 became effective on October 1, 2024.
ICD-10-CM Code B37.49: Other Urogenital Candidiasis
Depending on the specifics of the case, B37.49, a billable ICD-10-CM code for “Other urogenital candidiasis,” might be applicable to candidiasis of the groin.
Urogenital refers to the urinary and genital organs. Candidiasis of the groin could fall under this category, particularly if the infection extends to nearby areas of the urinary or genital systems, where understanding the difference between male and female discharge is crucial for accurate diagnosis. The 2025 edition of code B37.49 went into effect on October 1, 2024.
It’s critical to pinpoint the precise anatomical location when selecting the correct ICD-10 code to ensure accurate billing and record-keeping.
Distinguishing Between B37.2 and B37.49 when Coding for Groin Candidiasis
Choosing the right ICD-10 code for candidiasis of the groin hinges on precise documentation. Your doctor’s notes are key! If the infection is only on the skin of the groin, B37.2 might be right. But, if the infection has spread to the urogenital area, B37.49 could be more accurate.
Sometimes, you might even need multiple codes to fully describe what’s going on with the patient.
Frequently Asked Questions
What is the ICD-10 code for L08.9?
ICD-10 code L08.9 represents “Other specified local infections of the skin and subcutaneous tissue.” It’s a fairly general code, so for candidiasis of the groin, a more specific code would be preferable, if available.
What is the ICD-10 code for left groin fungal infection?
If the fungal infection in the left groin is specifically candidiasis, the code B37.2 would apply. If it’s a different type of fungal infection, such as tinea cruris, the ICD-10 code would be B35.6.
What is candidiasis in the pubic area?
Candidiasis in the pubic area is a fungal infection caused by Candida yeast. It can cause itching, redness, and a burning sensation. It’s more common in areas with folds of skin, like the groin, due to the warm, moist environment.
What is the ICD-10 code for Candidiasis in the groin?
The ICD-10 code for candidiasis (a yeast infection) in the groin is B37.2 (Candidiasis of skin and nails).
What is the difference between tinea and candidiasis in the groin?
Tinea cruris (“jock itch”) is a fungal infection caused by dermatophytes, while candidiasis is caused by Candida yeast. While both can cause similar symptoms like itching and redness in the groin area, they are different types of fungi and may require different treatments. A healthcare provider can determine the specific cause and recommend the appropriate antifungal medication.
Wrapping Up
Using the right ICD-10 code matters. It ensures a proper diagnosis, and it’s essential for healthcare providers to get paid correctly. So, it’s really important to use the most accurate code.
For candidiasis of the groin, the codes you’ll likely need are B37.2 and B37.49, depending on the specific situation.
Good documentation and a solid understanding of the coding guidelines are key to making sure everything’s done right.
