Diabetic Pedicure with Two Abnormal Toenails and a Toe Fissure
A 58-year-old new client books a deluxe pedicure with callus removal, gel polish, and a hot-stone add-on. His intake form lists type 2 diabetes with an A1c of 8.9% last month, numbness in both feet, and a stubbed toe he "didn't notice" until he saw blood. He takes metformin and warfarin. On examination: the right great toenail is thickened and yellow-brown with subungual debris and no pain; the left great toenail shows a dark green-black discoloration along the lateral edge with the plate lifting from the bed; between the toes of the left foot there is a 1 cm shallow fissure with macerated white skin. Both heels are callused, pedal pulses are weak, and the skin is warm and dry with no other open areas. Your license permits beautifying and shaping nails; diagnosing and treating disease is outside it.
1. Which parts of the requested service will you perform today and which will you refuse? Give the reason for each refusal.

Refuse the deluxe package as booked. Each component has its own problem.
- Callus removal with a blade or credò: refused. Neuropathy plus weak pulses plus an A1c of 8.9% means a nick can become an ulcer before he feels it, and poor perfusion impairs healing. The warfarin makes bleeding harder to stop on top of that. Callus on a neuropathic foot is a medical management issue.
- Hot-stone add-on: refused. He cannot reliably sense heat, so a stone hot enough to help is hot enough to burn without feedback. Thermal injury on a neuropathic foot is a known route to a serious wound.
- Gel polish: refused on both great toenails - it seals a diseased nail and traps moisture under a lifted plate. On unaffected nails it could be considered, but given the overall picture I would decline it for today.
- Soaking: the toe fissure is a break in the skin; prolonged soaking macerates it further and gives organisms an entry point.
What is defensible today: a dry service only - light filing and shaping of the unaffected nails with single-use files, gentle cleansing with minimal water, and thorough drying. Nothing sharp, nothing hot, nothing sealed.
2. Explain what you suspect about each of the two great toenails and what you are and are not allowed to do about them.

Right great toenail - thickened, yellow-brown, subungual debris: the pattern is consistent with a fungal nail infection. You cannot diagnose it; you can only describe what you see and send him for diagnosis. Do not drill, do not thin the plate to "reach" the debris, do not apply polish, do not apply any over-the-counter treatment as if prescribing. Thinning a diabetic nail with reduced sensation is exactly how a plate gets injured unnoticed.
Left great toenail - dark green-black along the lateral edge with onycholysis: the color and the lifted plate point toward a bacterial colonization under the nail rather than pigment. Whatever the cause, an onycholytic nail is a reservoir, and polish would trap it.
The line you hold on both: shape and beautify the nail plate - that is your scope. Identify, diagnose, and treat disease - that is not. Describe in the record, refer, and do not name a condition to the client as a conclusion. Say "this needs a podiatrist to look at it" rather than "this is fungus."
If he asks you to "just file it down and cover it," the answer is no, and the reason is the same one that governs the callus: he cannot feel what is being done to that foot.
3. Set out the referral, the aftercare advice, and the documentation for this visit.

Referral: send him to a podiatrist or his physician for both great toenails and for the toe fissure, and state that his calluses should be managed medically given the neuropathy and A1c. Ask him to obtain clearance before any water-based pedicure or polish. Offer to write the findings on a card so he can hand it over.
Aftercare advice:
- Dry carefully between the toes after washing and keep the fissure covered as directed by his provider.
- Inspect both feet daily, including the soles and between the toes, using a mirror - he cannot rely on sensation to warn him.
- Never use a blade, corn plaster, or medicated pad on his own feet.
- Well-fitting shoes and no walking barefoot.
Documentation:
- The A1c, the medications (metformin, warfarin), the reported numbness and the unnoticed injury.
- A description of each finding, in observational language, with location.
- Each service refused and the reason, plus the services actually performed and the tools used.
- The referral given, and his signed acknowledgment that services were declined for medical reasons and that he was referred.
- A note to require provider clearance before his next appointment.
What protects him and you is the record showing you recognized the limits of a nail license on a high-risk foot.
