What ICD-10 Codes Are Used for Onychomycosis?
Onychomycosis, or fungal nail infection, has several associated ICD-10 codes. Here are the common onychomycosis ICD codes:
- B35.1 - Tinea Unguium: This fungal infection affects one or more nails, commonly known as onychomycosis.
- L60.1 - Onycholysis: Although not specifically onychomycosis, this condition involves the separation of the nail from the nail bed, often a complication of fungal infections.
- L60.3 - Nail Dystrophy: This disorder leads to abnormal nail formation, often due to persistent fungal infections.
- L60.4 - Beau's Lines: Horizontal depressions in the nails can be due to onychomycosis.
- L60.5 - Yellow nail syndrome: This condition involves nail thickening and yellow to yellow-green discoloration and can sometimes involve fungal infection.
Which Onychomycosis ICD Codes Are Billable?
Before we delve into the specific codes, it's worth noting that a billable code is detailed enough to specify a medical diagnosis.
- B35.1 - Yes, this is billable and is used to specify a diagnosis for Tinea Unguium or Onychomycosis.
- L60.1 - Yes, this billable code represents Onycholysis which may be a complication of onychomycosis.
- L60.3 - Yes, Nail Dystrophy is billable, often coded when onychomycosis causes abnormal nail formation.
- L60.4 - Yes, Beau's Lines are billable, even when caused by a persistent case of onychomycosis.
- L60.5 - Yes, Yellow Nail Syndrome is billable and sometimes involves a fungal infection.
Clinical Information
Onychomycosis is a common fungal infection of the nails that usually makes the nail thickened, discolored, and brittle. It can be a source of significant discomfort and distress because it may interfere with daily activities. Detailed insights about Onychomycosis include:
- Dermatophytes primarily cause it, but yeasts and molds can also be culprits.
- The infection can spread from a fungal skin infection, such as an athlete's foot.
- Older adults, individuals with diabetes, and those with a weakened immune system are at higher risk.
- Treatment typically includes antifungal medications, but some cases may require nail removal.
- Prevention strategies include good foot hygiene, keeping the feet dry, and avoiding sharing nail clippers or shoes.
Synonyms Include:
- Tinea Unguium
- Fungal Nail Infection
- Nail Fungus
- Dermatophytic Onychomycosis
- Dystrophic Nails
Commonly asked questions
Yes, the fungus causing onychomycosis can spread to other body areas, especially if left untreated. It's common to spread to the skin, causing conditions like athlete's foot.
The duration of treatment can vary depending on the severity of the infection. It usually takes several weeks to months of antifungal therapy for the disease to resolve completely.
Yes, recurrence is quite familiar with onychomycosis, even after successful treatment. Regular foot care and preventive measures can help reduce the chances of recurrence.
