- Gender Disparity: Studies show that men are more likely to be affected than women, with a ratio of 2:1.
Symptoms of Onychomycosis
Individuals with onychomycosis may experience a range of symptoms, including:
- Discoloration: The nail might look yellow, brown, or white.
- Thickening: The nail often becomes thickened, making it difficult to trim.
- Brittleness: Nails may become brittle and prone to breaking or flaking.
- Distorted Shape: The shape of the nail may become irregular.
Impact on Quality of Life
Onychomycosis can lead to physical discomfort, reduced mobility, and psychological distress. The embarrassment associated with visible nail infections may discourage individuals from participating in social activities, affecting their overall well-being.

The ICD-10 coding system is designed to categorize diseases and health conditions systematically. For onychomycosis, the most relevant codes are as follows:
Primary Code for Onychomycosis
- B35.1: This code specifically covers dermatophytic onychia and related fungal infections. It is the go-to code for documenting cases of nail fungus.
Breakdown of ICD-10 Codes by Body Regions
To facilitate better understanding and usage, the following table categorizes ICD-10 codes based on the affected body regions.
| Body Region | ICD-10 Code | Description |
|---|---|---|
| Onychomycosis of Feet | B35.1 | Onychomycosis due to dermatophyte |
| B35.3 | Tinea pedis (athlete’s foot) | |
| L03.03 | Cellulitis of toe caused by fungal infections | |
| Onychomycosis of Hands | B35.1 | Onychomycosis caused by dermatophytes |
| B35.2 | Tinea manuum (fungal infection of the hands) | |
| L03.01 | Cellulitis of the finger caused by fungal infections | |
| Skin Infections Related | B35.9 | Dermatophytosis, unspecified |
| B35.4 | Tinea corporis (ringworm of the body) | |
| B35.6 | Tinea cruris (jock itch) | |
| Scalp and Other Infections | B35.0 | Tinea capitis (scalp ringworm) |
| B36.0 | Tinea versicolor (yeast infection) |
Detailed Explanation of Key Codes
Onychomycosis of Feet (Toenails)
B35.1: Used for cases of fungal nail infections primarily caused by dermatophytes. This code is applicable when diagnosing onychomycosis in one or both feet.
B35.3: Tinea pedis, commonly known as athlete’s foot, is included in this category. This condition often coexists with onychomycosis, requiring dual coding.
L03.03: This code is used to document cellulitis of the toe, which can arise as a secondary complication of untreated onychomycosis.
Onychomycosis of Hands (Fingernails)
While less common, fingernail infections also require specific coding:
B35.1: This code is applicable for fingernail fungal infections caused by dermatophytes.
B35.2: Tinea manuum applies to fungal infections affecting the skin of the hands, which may be seen alongside nail infections.
L03.01: Used for cases of cellulitis of the finger resulting from fungal infections.
Skin Fungal Infections Related to Onychomycosis
Skin infections often accompany nail infections, necessitating additional codes:
B35.9: This code is used when the specific site of the dermatophytosis is not documented.
B35.4: Tinea corporis, or ringworm of the body, may be associated with nail fungal infections.
B35.6: Tinea cruris, often referred to as jock itch, is another condition linked to onychomycosis.
Scalp and Other Specific Fungal Infections
Fungal infections can extend to the scalp and other areas:
B35.0: Tinea capitis primarily affects the scalp and hair, and is important to document in patients with broader dermatophyte concerns.
B36.0: Tinea versicolor is included here, marked by skin pigmentation changes due to yeast infections.
Comorbid Conditions and Multiple Nail Infections
When fungal infections coexist with other medical conditions, specific codes must be utilized:
E11.620: This code is for patients with type 2 diabetes mellitus who also have diabetic dermatitis, which can complicate fungal infections.
B35.1: This code can also be used for documenting onychomycosis of multiple toenails in patients with diabetes, emphasizing the importance of detailed coding.
