Custom Claude Project: Build Your Dental Assistant Writing Assistant

What This Builds

Instead of re-explaining who you are and what you need every time you open Claude, you'll have a permanent "Dental Assistant Writing Assistant" that already knows your practice, your common procedures, your preferred tone, and your output format. Every conversation starts from the same foundation — no setup, no repeated context. Writing insurance narratives, patient letters, post-op instructions, and appeal letters becomes a 90-second task.

Prerequisites

• Comfortable using Claude for basic writing tasks (Level 3)
• Claude Pro subscription ($20/month — required for Projects feature)
• Your practice information (name, phone, address, common procedures)
• Time needed: 60–90 minutes to build; 90 seconds per use
• Cost: $20/month (Claude Pro)

The Concept

A Claude Project is like hiring a new coworker who has already read your office manual, knows your procedures, and knows exactly how you like things written. You set it up once — loading it with context about your practice, your procedures, and your preferences. Then every conversation you start in that Project already has that knowledge. Ask for a crown narrative, and it already knows your practice name, your preferred clinical tone, and your formatting preferences. No re-explaining. Ever.

Build It Step by Step

Part 1: Create the Project

1. Log into claude.ai → click Projects in the left sidebar (you'll see this only with a Pro account)
2. Click New Project
3. Name it: "Dental Assistant Writing Assistant"
4. Click Create Project

What you should see: A project workspace with a chat interface and a "Project Instructions" panel on the right side.

Part 2: Write Your System Instructions

Click Project Instructions → paste the following, replacing bracketed items with your actual practice info:

You are a dental assistant writing assistant for [PRACTICE NAME], a private dental practice.

ABOUT THIS PRACTICE:
- Practice name: [PRACTICE NAME]
- Dentist: [DR. NAME]
- Address: [ADDRESS]
- Phone: [PHONE NUMBER]
- PMS software: [DENTRIX / EAGLESOFT / OPEN DENTAL]
- Common procedures: crowns (D2740/D2750), implants (D6010), extractions (D7140/D7210),
  root canals (D3330), SRP (D4341/D4342), composites (D2391-D2394), bridges (D6240)

WRITING TASKS I NEED:
1. Insurance claim narratives (3-5 sentences, clinical language, CDT codes)
2. Prior authorization letters (1 page, clinical necessity focus)
3. Insurance appeal letters (professional, assertive, addresses denial reason directly)
4. Post-op instructions (patient-friendly, 8th grade reading level, bullet points)
5. Procedure explanations for patients (plain language, reassuring, 4-5 sentences)
6. Patient communication letters (recall, incomplete treatment, post-op follow-up)
7. Specialist referral letters (professional, includes clinical summary and request)

OUTPUT RULES:
- Use [BRACKETS] for any information I need to fill in (tooth number, patient name, specific findings)
- For clinical documents: professional clinical dental language
- For patient-facing documents: 8th grade reading level, warm tone, no jargon
- No disclaimers, no "I recommend consulting a professional" — just clean, usable output
- Keep narratives under 5 sentences unless I ask for more
- Always include CDT codes when relevant

HIPAA NOTE: I will never enter real patient names or identifying information.
All requests use hypothetical clinical scenarios or procedure codes only.

Click Save Instructions.

Part 3: Upload Reference Documents (Optional but Powerful)

Claude Projects let you upload files that every conversation can reference. Consider uploading:

1. Your CDT Code Reference — A list of your 15 most common CDT codes with descriptions. You can ask Claude to generate this first ("List the 15 most common CDT codes for general dentistry with their descriptions in a table"), copy the output, save as a text file, and upload.

2. Your Common Insurance Payers — A text file listing the 3-5 insurance carriers you submit to most, and any payer-specific notes (e.g., "Delta Dental prefers concise narratives under 4 sentences").

To upload: In the Project workspace, look for a paperclip or "Add content" button → upload your text or PDF files.

Part 4: Test and Refine

Start a new conversation in your Project. Test these requests and evaluate the output quality:

1. "Write a narrative for a crown D2740 on a posterior tooth. Clinical: cracked tooth, deep decay, failing restoration."
2. "Write post-op instructions for extraction. Friendly, bullet points."
3. "Write an appeal for D4341 denied for frequency limitation."

For each output, ask yourself: Is it immediately usable? Does it sound like it came from your practice? If not, update the Project Instructions with the specific change needed.

Real Example: Full Insurance Documentation Session

Setup: You configured the Project for [PRACTICE NAME] with Dr. Rodriguez. You have 6 claims to work through on a Friday afternoon.

Input (into your Project): "I need 3 narratives: D2740 crown tooth #14 (cracked tooth syndrome, large failing restoration), D6010 implant tooth #30 (extracted after failed RCT), D4341 SRP maxillary right (pockets 5-7mm, generalized bleeding, bone loss on X-ray)."

Output you get: Three separate, labeled narratives, each 3-5 sentences, each with [TOOTH NUMBER] or other placeholders filled in from what you gave it — ready to copy into your claim software.

Time saved: 45+ minutes → under 5 minutes.

What to Do When It Breaks

• "Project Instructions" button is missing → You may be on the free tier. Claude Projects requires Pro ($20/month).
• Outputs don't match your preferred tone → Update the Project Instructions "WRITING TASKS" or "OUTPUT RULES" section with more specific guidance. Be explicit: "Narratives should always start with the chief complaint, then the clinical finding, then the rationale."
• CDT codes are wrong or unfamiliar → Specify the full CDT code and description in your prompt. Claude knows CDT codes but may need the specific version you use.
• Claude forgets previous outputs within a session → It shouldn't in a Project, but if it does, reference the previous output explicitly: "Using the same tone as the crown narrative above, write..."

Variations

• Simpler version: Use Custom Instructions in the free ChatGPT tier instead — less powerful but free. You lose the file uploads and the persistent project structure but get most of the benefit.
• Extended version: Add a "Template Library" document to the Project with your 10 best narrative examples. Claude can match the style of your examples when generating new ones.

What to Do Next

• This week: Build the Project and run your first 5 real narratives through it
• This month: Refine the instructions based on where the outputs fall short; add your CDT reference file
• Advanced: Add payer-specific instructions to get narratives calibrated for Delta Dental, MetLife, or your primary carriers
