Bookkeeping for Dental Practices: Insurance, Labs & Equipment

The Financial Complexity of Dental Practices

Running a dental practice means managing a business that combines healthcare delivery with significant capital investment, complex revenue streams, and demanding compliance requirements. Your bookkeeping needs to handle health fund claims, patient gap payments, lab fees, equipment depreciation, and staffing costs - all while giving you clear visibility over practice profitability.

Revenue Streams in Dentistry

Dental practice revenue comes from multiple sources that need to be tracked separately.

Patient Fees

Patient fees can be broken down into:

• Health fund claims - The portion paid by the patient's private health insurer. These are processed through HICAPS or a similar claiming terminal and deposited into your bank account (usually within a few business days).
• Gap payments - The difference between your fee and the health fund rebate, paid by the patient at the time of service.
• Full-fee patients - Patients without health insurance who pay the full fee.

Track each of these separately. Knowing your payer mix (what percentage of revenue comes from health funds versus gap payments versus full-fee patients) helps you understand your revenue sensitivity.

Medicare Claims

Some dental services are covered under the Child Dental Benefits Schedule (CDBS) or other Medicare programs. These payments come from Services Australia and follow a different claiming and payment timeline. Track Medicare revenue separately from private health fund revenue.

Procedure-Based Revenue Tracking

Consider tracking revenue by procedure type:

• General dentistry (check-ups, fillings, cleans)
• Orthodontics
• Prosthodontics (crowns, bridges, dentures)
• Endodontics (root canals)
• Oral surgery (extractions, implants)
• Cosmetic dentistry (veneers, whitening)

This level of detail shows you which services drive the most revenue and margin, helping you make informed decisions about which areas to invest in or market.

Lab Fees: A Major Cost Centre

Dental lab fees for crowns, bridges, dentures, and other prosthetics represent a significant expense. Managing lab costs requires careful bookkeeping.

Track lab fees per patient and per job. When you send a job to the lab, record:

• The patient name and procedure
• The lab used
• The quoted cost
• The actual invoice amount
• The date sent and date returned

Match lab invoices to patient revenue. This lets you calculate the margin on prosthetic work. If you charge $1,800 for a crown and the lab fee is $400, your margin before chair time and materials is $1,400.

Reconcile lab statements monthly. Labs typically send monthly statements. Match every line item to your records and query any discrepancies promptly.

Equipment and Depreciation

Dental equipment represents a major capital investment:

• Dental chairs and units - $30,000 to $80,000 each
• X-ray equipment - $10,000 to $100,000+ depending on the type
• Sterilisation equipment - $5,000 to $20,000
• Compressors and suction units - $5,000 to $15,000
• Handpieces - $1,000 to $3,000 each (you will need many)
• IT systems and practice management software - Variable

Record each major item as an asset and depreciate over its effective life. The ATO provides effective life estimates for medical and dental equipment. Common effective lives include:

• Dental chairs: 10 years
• X-ray units: 10 years
• Sterilisation equipment: 7 years
• Compressors: 10 years
• Computers: 4 years

Check the current instant asset write-off threshold. Eligible items can be fully deducted in the year of purchase, which can provide substantial tax savings for practices investing in new equipment.

Staffing and Payroll

Dental practices employ a range of staff:

• Dental assistants - Under the Health Professionals and Support Services Award
• Dental hygienists and therapists - May be employees or contractors
• Reception and administration staff - Under the relevant clerical award
• Practice managers - Often on individual contracts
• Associate dentists - May be employees or contractors (this is a critical distinction)

Associate Dentist Arrangements

Associate dentists often work under a service agreement where they receive a percentage of the fees they generate (commonly 40-45%). The bookkeeping treatment depends on whether they are an employee or contractor:

Employee associate - You pay them through payroll, withhold PAYG, pay super, and provide leave entitlements.

Contractor associate - They invoice you for their services. No PAYG withholding or super (in most cases). They are responsible for their own tax and insurance.

The ATO scrutinises these arrangements, so ensure the engagement genuinely reflects a contractor relationship if that is the structure you use.

Consumables and Supplies

Dental consumables (gloves, masks, composite resin, impression materials, anaesthetic, bonding agents) are a significant ongoing cost. Track consumable purchases in a dedicated expense account.

Consider doing quarterly stock counts of high-value consumables. This helps you identify waste, theft, or ordering inefficiencies.

Insurance

Dental practices need several types of insurance:

• Professional indemnity - Covers claims of negligence or malpractice
• Public liability - Covers injury to patients or visitors on your premises
• Workers compensation - Mandatory for all employees
• Equipment insurance - Covers damage to or theft of expensive dental equipment
• Business interruption - Covers lost income if the practice cannot operate
• Cyber insurance - Increasingly important given the sensitive patient data you hold

Record each insurance policy as a separate expense. Annual premiums should be spread over 12 months using prepayment accounting for accurate monthly reporting.

GST Considerations

Most dental services are GST-free because they are health services provided by registered practitioners. However:

• Cosmetic dental services that are not clinically necessary are subject to GST
• Retail product sales (toothbrushes, whitening kits, mouthguards sold over the counter) are subject to GST
• Lab fees you pay may include GST depending on the lab's registration status
• Equipment purchases and consumables include GST that you can claim as input tax credits

Keep your GST categories clean. Mixing up GST-free and taxable items on your BAS will cause problems. An automated categorisation tool like SortBooks helps ensure each transaction is coded correctly.

Key Financial Metrics for Dental Practices

Monitor these numbers regularly:

• Revenue per chair per day - Are your chairs being utilised efficiently?
• Lab costs as a percentage of prosthetic revenue - Should be around 15-25%
• Consumable costs as a percentage of revenue - Typically 5-8%
• Staff costs as a percentage of revenue - Typically 25-35%
• Net profit margin - After all expenses, what percentage of revenue is profit?

Setting Up Your Practice Bookkeeping

1. Use practice management software (Dental4Windows, EXACT, Dentally) integrated with your accounting platform
2. Track revenue by payer type and procedure category
3. Record lab fees per patient and reconcile monthly
4. Set up asset registers and depreciation schedules for equipment
5. Run payroll correctly for all staff types
6. Reconcile health fund deposits against claims
7. Review practice financials monthly with your accountant or bookkeeper

A well-managed dental practice is a profitable dental practice. Keep your books as clean as your instruments and you will always have a clear picture of your financial health.
