Dental procedures require precise coding for insurance claims, and CPT Code G0105 plays a crucial role in billing for specific dental services, particularly amalgam fillings. Amalgam fillings, made from a mixture of metals, have been a staple in dentistry for over a century due to their durability and cost-effectiveness. However, with evolving dental technologies and patient preferences, understanding the cost, billing process, and alternatives to amalgam fillings is essential for both dental professionals and patients.
This article provides an in-depth exploration of CPT Code G0105, the cost factors of amalgam fillings, insurance considerations, and how they compare to modern alternatives like composite resin. Whether you’re a dentist, billing specialist, or patient, this guide will help you navigate the financial and clinical aspects of amalgam restorations.
CPT Code G0105
2. Understanding CPT Code G0105
Definition and Purpose
CPT Code G0105 is a Healthcare Common Procedure Coding System (HCPCS) code used primarily in Medicare billing for:
*”G0105 – Prostate cancer screening; digital rectal examination and/or collection of specimen(s) for laboratory test(s).”*
Wait—does this relate to dental fillings? No, there seems to be confusion here. G0105 is not a dental code. The correct dental codes for amalgam fillings fall under the Current Procedural Terminology (CPT) codes, such as:
-
D2140 – Amalgam, one surface
-
D2150 – Amalgam, two surfaces
-
D2160 – Amalgam, three surfaces
-
D2161 – Amalgam, four or more surfaces
However, if you’re looking for Medicare-covered preventive dental services, the correct code might be G0127 (periodontal scaling in Medicare patients).
Why the confusion? Many dental offices mistakenly use G0105 when they mean D2000-D2999 (restorative codes). Always verify codes with the American Dental Association (ADA) or CMS guidelines.
When Is G0105 Actually Used?
-
Prostate cancer screenings under Medicare
-
Not applicable for dental procedures
For amalgam fillings, dentists should use ADA CDT codes (D2000-D2999 series).
3. Amalgam Fillings: An Overview
What Are Amalgam Fillings?
Amalgam fillings, also called “silver fillings,” are a mixture of:
-
Mercury (50%)
-
Silver, tin, copper (50%)
They have been used since the 1800s due to their:
✔ Durability (last 10-15 years)
✔ Cost-effectiveness (cheaper than composite)
✔ Strength (ideal for molars)
Safety Concerns
Despite their long history, concerns about mercury toxicity have led to debates. However, the FDA and ADA confirm that amalgam is safe for most patients, except:
-
Pregnant women
-
Children under 6
-
People with kidney disorders
4. Cost of Amalgam Fillings
Factors Influencing Cost
| Factor | Impact on Cost |

| Dentist’s location | Urban areas cost more |
| Insurance coverage | PPO vs. Medicaid differences |
| Material choice | Amalgam vs. composite |
Average Pricing in the U.S.

5. Comparing Amalgam vs. Composite Fillings
| Feature | Amalgam | Composite |
|---|---|---|
| Cost | $50-$150 | $90-$250 |
| Durability | 10-15 years | 5-10 years |
| Aesthetics | Silver, noticeable | Tooth-colored |
10. Conclusion
Understanding dental billing codes (like D2140-D2161 for amalgam fillings) is crucial for accurate insurance claims. Amalgam fillings remain a cost-effective, durable option, though composite alternatives are growing in popularity. Patients should weigh cost, longevity, and aesthetics when choosing fillings.
