Diagnostic (D0100-D0999)

D0120: Periodic oral evaluation – established patient

A periodic oral evaluation for established patients is an examination to see if the patient’s dental and medical health have changed since the last examination. When necessary, it also includes x-ray, periodontal and oral cancer evaluations.

D0140: Limited oral evaluation – problem focused

A limited oral evaluation is one that only looks at a certain issue or condition relating to oral health. A patient who requires this type of evaluation typically has a dental emergency, such as trauma or a severe infection. Common problems can include chipped or broken teeth, dental trauma, etc.

D0150: Comprehensive oral evaluation – new or established patient

When a general dentist evaluates the patient, they perform a comprehensive oral evaluation on new patients or existing patients who haven’t been seen in a while to get a baseline assessment of the patient’s overall oral health of the teeth, gums, jaw, etc.

D0180: Comprehensive periodontal evaluation – new or established patient

Comprehensive periodontal evaluation refers to the evaluation of periodontal problems, probing and charting, evaluation and recording of new or established patients’ dental and medical histories, and general health assessments.

D0210: Intraoral – complete series of radiographic images

“Intraoral” refers to a complete and extensive radiographic examination of the entire mouth. It typically consists of 14 to 22 posterior bitewing images taken from the periapical and wing areas of the teeth to display the crowns and roots of all teeth and the alveolar bone.

D0220: Intraoral – periapical first radiographic image

Dental disorders like tooth decay, abscesses, and periodontal (gum) disease can all be diagnosed more easily with the use of intraoral periapical images, which reveal the roots of teeth in addition to their crowns.

D0251: Extra-oral posterior dental radiographic image

Extraoral radiographs are used to look into areas that intraoral films cannot reach or to check the cervical spine, skull, and face, including the maxilla and mandible, for diseases, injuries, or anomalies. Standardized extraoral radiographs can be used to monitor the evolution of a patient’s care.

D0274: Bitewings- four radiographic images

Bitewing radiographimages offer high-resolution images of both sides of the mouth, focusing on the back of the jaw from the canines rearward, and are often obtained in a four-film series.

D0330: Panoramic radiographic image

A two-dimensional (2-D) dental x-ray examination produces a panoramic radiographic image by taking a single image of the entire mouth, including the teeth, upper and lower jaws, surrounding structures, and tissues.

Preventive (D1000-D1999)

D1110: Prophylaxis – adult

Prophylaxis, commonly known as an “prophy”, is a preventative dental procedure typically dental hygienists carry it out during an adult’s preventative visit to clear the mouth of dental plaque, tartar / calculus, and stain.

D1120: Prophylaxis – child

During dental prophylaxis, the hygienist delicately removes calculus, tartar, and/or stain from the teeth of children, and then the teeth are then polished. This procedure is typically recommended once every six month for optimal oral health.

D1206: Topical application of fluoride varnish

When applied with a brushing, fluoride varnish offers additional protection against tooth decay. The pale yellow gel swiftly settles when fluoride varnish is put on kids’ teeth with a gentle brush. The varnish hardens quickly and smells and tastes like fruit.

D1351: Sealant – per tooth

The chewing surfaces of the rear teeth can be coated with dental sealants, which are thin coatings that can prevent cavities for a very long time. Sealants shield the chewing surfaces from cavities by establishing a barrier between them and food and microorganisms.

Restorative (D2000-D2999)

D2330-D2394: Tooth colored filling – Resin-based composite

Composite resins, sometimes known as tooth-colored fillings, offer good durability and resistance to fracture for small- to medium-sized fillings that must bear moderate pressure from the ongoing stress of chewing. They can be applied to either the front or back teeth.

D2740: Crown – porcelain/ceramic substrate

The most realistic appearance is achieved with porcelain or ceramic crowns when used on front and back teeth to restore a tooth damaged by decay or trauma. In terms of size, color, and shape, they complement the teeth around them. They don’t utilize any metal because they are biocompatible.

D2950: Core buildup, including any pins when required

Core buildup, including any pins, refers to the augmentation of the anatomical crown during the placement of a restorative crown. When the tooth’s strength and retention are insufficient for the crown treatment, a substance is inserted in the tooth’s preparation for a crown.

Endodontics (D3000-D3999)

D3310-D3330: Endodontic therapy

Endodontic therapy entails various procedures, including removing pulpal tissue, contouring and filling the root canals, obturation of the root canal area, and inserting a long-lasting dental restoration.

D3346-D3348: Retreatment of previous root canal therapy

Remedial treatment if the primary root canal therapy gets reinfected. The tooth’s root canal filling materials are taken out, and the canals are then re-cleaned, shaped, and sealed to remove any remnants or infection from the initial root canal.

Periodontics (D4000-D4999)

D4341: Periodontal scaling and root planing – four or more teeth per quadrant

Patients with periodontitis often need scaling and root planing, which is used when four or more teeth are comprimised. If not treated, the teeth will become loose and eventually fall out. So, scaling and root planing is used to remove build-up and smoothing the teeth above and below the gumline.

D4342: Periodontal scaling and root planing – one to three teeth per quadrant

According to each quadrant, periodontal scaling and root planing involve instrumenting the teeth’s crown and root surfaces to remove plaque and calculus. It is prescribed for those who have periodontal disease and has a therapeutic, not preventative, purpose.

D4910: Periodontal maintenance

A dental procedure that entails cleaning plaque and tartar from below and above the gum line, all the way down the length of each tooth to the point where the root, gum, and bone converge. Often antibacterial medications are used, and rough parts of the roots may need to be softened if necessary.

D4355: Full mouth debridement to enable comprehensive evaluation and diagnosis

Full mouth debridement is treats significant plaque accumulation. This procedure is required when extensive plaque and calculus make it difficult to adequately reach tooth surfaces or periodontal areas, inhibiting the dentist from thoroughly examining the patient’s teeth and gums.

Prosthodontics (D5000-D5899)

D5110: Complete denture – maxillary

To replace all teeth missing on one’s upper jaw teeth, a maxillary denture is used. Also called false teeth, dentures are frequently made of acrylic resin and designed to closely resemble the actual gums and teeth which are seated on the top jaw and help restore normal function and esthetics.

D5120: Complete denture – mandibular

To replace all teeth missing on one’s lower jaw teeth, a mandibular denture is used. Also called false teeth, dentures are frequently made of acrylic resin and designed to closely resemble the actual gums and teeth which are seated on the bottom jaw and help restore normal function and esthetics.

D5130: Immediate denture, maxillary

The immediate maxillary denture is a dental prosthesis designed to replace the missing teeth and associated maxillae / upper jaw components. It is placed right after the extraction of the last remaining tooth.

D5140: Immediate denture, mandibular

The immediate mandibular denture is a dental prosthesis designed to replace the missing teeth and associated mandibular / lower jaw components. It is placed right after the extraction of the last remaining tooth.

D5211: Maxillary partial denture – resin base (including any conventional clasps, rests, and teeth)

The only areas of the tooth arch supported by the acrylic resin removable partial denture are the edentulous areas and, in the case of the maxilla, the hard palate. The acrylic resin removable partial denture offers three advantages over other forms of partial dentures.

D5213: Maxillary partial denture – cast metal framework with resin denture bases (including any conventional clasps; rests and teeth)

A cast metal framework with artificial teeth set in acrylic resin is known as a partial cast denture, a detachable partial denture. Cast Partial Denture is stronger, more resilient, and more durable than a typical acrylic denture.

D5214: Mandibular partial denture – cast metal framework with resin denture bases (including any conventional clasps; rests and teeth)

One of the most popular solutions for a mandibular partial denture is one with a cast metal framework and resin denture bases. It has a strong, incredibly thin metal base that supports a row of acrylic teeth. Metal clasps secure the denture to natural teeth, similar to partial acrylic dentures.

D5863: Overdenture, complete maxillary

For the edentulous maxilla, an implant overdenture offers a stabilized removable option that boosts patient happiness and quality of life. In some studies, a palateless design supported by four to six implants and a large anteroposterior span has been successfully used.

D5864: Overdenture, partial maxillary

Removable partial dentures, called partial maxillary overdentures, are frequently used to replace various teeth in the upper jaw. Additionally, they can make it easier for the wearer to speak and eat, and can maintain the position of your mouth’s remaining teeth, which could change with time.

D5865: Overdenture, complete, mandibular

A detachable denture covers the retained teeth, tooth roots, or dental implants in the mandibular complete overdenture procedure.

D5866: Overdenture, partial mandibular

Multiple teeth in the lower jaw are routinely replaced by removable partial dentures, also known as partial mandibular overdentures. They can also make it simpler for the wearer to speak and chew. Additionally, partial dentures help keep the remaining teeth in your mouth from shifting over time.

Implant Services (D6000-D6199)

D6010: Surgical placement of implant body: endosteal implant

A dental implant are inserted into the jawbone to act as an artificial root system for holding a replacement tooth, bridge, or denture. When a tooth is lost, dental implants are frequently inserted and are the most often used dental implants and are typically comprised of titanium.

D6059: Abutment supported porcelain fused to metal crown (high noble metal)

An abutment installed on the implant body provides support and stability for an abutment-supported or retainer crown. The three separate parts are the implant body, abutment, and crown, or retainer crown. The separate crown is then attached to the abutment, first positioned on the implant body.

Prosthodontics, fixed (D6200-D6999)

D6240: Pontic – porcelain fused to high noble metal

The pontic refers to an artificial tooth connected to a dental bridge using a single prosthetic. It looks like a natural tooth since an attachment supports it. The technique creates an artificial tooth with remarkable compression and tensile strength, covering the underlying metal.

D6750: Implant Crown – porcelain fused to high noble metal

An implant crown made of high noble metal and porcelain symbolizes a hybrid construction in which porcelain is fused as a covering over a metal substructure that houses the tooth. These crowns can offer both beautiful looks and durability.

Oral & Maxillofacial Surgery (D7000-D7999)

D7111: Extraction, coronal remnants deciduous tooth

Removing baby teeth that are loose and about to come out but haven’t because they are causing pain or can’t fall out on their own are extracted from a baby’s deciduous tooth as “coronal remnants.” It also goes by the name of pediatric extractions.

D7250: Surgical removal of residual tooth roots (cutting procedure)

A surgical root extraction removes dental roots stuck in the bone beneath the gum line after basic tooth extraction. Patients with tooth damage or injuries may also be eligible for the operation, particularly if dental x-rays showed that the dental root had been divided up or cut in some places.

D7140: Extraction, erupted tooth or exposed root (elevation and/or forceps removal)

A dental operation known as “erupted tooth extraction” especially refers to removing an erupted or visible tooth. An “open” extraction is another name for a surgical extraction. The strength of the crown and the tooth root’s curve affect the extraction type performed.

D7120: Surgical removal of erupted tooth requiring removal of bone and/or sectioning of d, and including elevation of mucoperiosteal flap if indicated

Surgical extraction is the removal of a tooth that presents clinically with a condition that does not safely or adequately allow access using a non-surgical approach. Surgical extractions require an incision, elevation, and bone removal when indicated.

D7220-D7240: Removal of impacted tooth

The four permanent adult teeth, known as wisdom teeth, are situated at the top and bottom back corners of your mouth. Impacted tooth extraction is a surgical operation to remove one or more of these teeth if it is impacted or causing you pain, infection, or other dental issues.

Orthodontics (D8000-D8999)

D8080: Comprehensive orthodontic treatment of the adolescent dentition

The goal of optimum alignment of all the teeth and jaws in good form and function is attained through comprehensive orthodontic treatment, either with metal brackets or invisible aligners. This treatment is often started in teens but is also used on adults and seniors.

Adjunctive General Services (D9000-D9999)

D9110: Palliative (emergency) treatment of dental pain – minor procedure

Because treatment is, by definition, symptomatic relief without a cure, it is typically administered in an emergency for dental pain. Before going to the dentist to fix the issue, you might need palliative treatment to relieve the pain.

D9230: Inhalation of nitrous oxide/anxiolysis, analgesia

Nitrous oxide is a gas with a slight, sweet fragrance and is virtually colorless and odorless. It is a potent analgesic and anxiety-relieving substance with little to no effect on the respiratory system and depresses the central nervous system.

D9910: Application of desensitizing medicament

Desensitizing medications seal the tiny pores of exposed root surfaces in patients more sensitive than mildly sensitive. Dentists apply desensitized medicaments to seal the tooth’s dentin layer, which causes sensitivity and discomfort.

D9940: Occlusal guard, by report

Bruxism causes teeth to clench and grind, and occlusal guards are built of hard or semi-rigid/soft materials to prevent this from happening. They could be made by a third-party laboratory or in the dentist’s office.


Invisalign is a form of dental treatment that uses clear, plastic aligners. A 3D scan of the patient’s mouth is customized for each patient’s aligners. After that, specially designed aligners are created to gradually shift the teeth into the desired position.
