Additional Information

Onychomycosis  is a chronic superficial fungal infection of nail unit. Onychomycosis can infect both fingernails and toenails with toenails being more prevalent. The most frequent cause of onychomycosis is Trichophyton rubrum, but other dermatophytes, including Trichophyton mentagrophytes and Epidermophyton floccosum, can also cause it. The dermatophytes are identified in 90% of the toenail and 50% of fingernail onychomycosis. Candida albicans cases account for 2% of onychomycosis, especially in fingernails. Nondermatophytic mold onychomycosis is cultured primarily from toenails. Examples of these saprophytic molds include Fusarium, Aspergillus, Acremonium, Scytalidium, and Scopulariopsis brevicaulis, accounting for about 8% of nail infections.

Statement on Medical Necessity
All ordered tests should be medically necessary for the diagnosis or detection of disease, illness, impairment, symptom, syndrome, or disorder and the results should be used in the medical management and treatment decisions for the patient. Solaris requires ICD-10 codes with each order for lab testing and both the tests ordered and the diagnosis should be documented in the provider’s medical record for the patient. The United States Department of Health and Human Services, Office of Inspector General, takes the position that a provider who orders medically unnecessary tests may be subject to civil penalties.

Panels and Profiles
Solaris offers Providers the convenience of ordering test combinations in a group at times with the flexibility to choose appropriate test(s) for individual patients. Providers should only order those tests that he or she believes are medically necessary for each patient, and a lesser inclusive profile or individual tests should be ordered if not all tests in the test combination/profile are medically necessary. All tests offered in a test combination/profile may be ordered separately as individual tests. Solaris encourages clients to contact their Solaris representative if the testing configurations shown do not meet individual needs for any reason, or if some other combination of procedures is needed.
