Does Colorado Medicaid cover deep cleanings and gum treatment?

Routine cleaning and periodontal treatment are not interchangeable

A routine cleaning is preventive care for a mouth that does not require active periodontal treatment. Scaling and root planing treats qualifying periodontal disease below the gumline, while full-mouth debridement can be used in specific circumstances when deposits prevent a complete evaluation. Periodontal maintenance follows active periodontal treatment when clinically appropriate.

Only a dental professional can diagnose the condition and choose the appropriate service. Bleeding gums or bad breath alone cannot establish which treatment or billing code is needed, and a benefit page cannot diagnose gum disease.

Adult periodontal services in the July 2026 summary

For adults, covered periodontal services generally count toward the $3,000 July–June annual limit that began July 1, 2026. A frequency listing does not guarantee that the clinical criteria are met or that the entire treatment plan is payable.

• Comprehensive periodontal exam: once every three years.
• Full-mouth debridement: once every three years.
• Periodontal maintenance: two per year.
• Scaling or root planing: once every three years per quadrant.
• Periodontal surgery: listed when the program's periodontal clinical criteria are met.

Children's periodontal care and EPSDT

The standard children's summary lists periodontal services for members age 0 through 20, with age and frequency qualifications on some services. It currently lists full-mouth debridement for ages 13–20, periodontal maintenance, scaling or root planing, and surgery that meets clinical criteria.

For a member under 21, EPSDT requires a case-specific medical-necessity review of Medicaid-coverable care. When treatment beyond a standard frequency is medically necessary, the provider should submit the records required for that review rather than promise an exception.

What the dentist may need to document

DentaQuest's Colorado provider resources place periodontal care under clinical criteria in the Office Reference Manual.

The provider determines which records are clinically appropriate and submits any required authorization. Members should ask whether the request is approved, partially approved, denied, or pending before non-emergency treatment begins.

• A current periodontal evaluation and diagnosis
• Tooth and gum measurements or charting when required
• Relevant X-rays or other diagnostic records
• The quadrants or teeth to be treated
• Prior periodontal treatment and maintenance history
• A narrative or other support when the standard record does not fully explain medical necessity
• Prior authorization when the current code and program require it

Questions before treatment—and symptoms that need prompt care

1. 1

   What is the diagnosis?

   Ask the dentist to explain whether the recommendation is routine cleaning, debridement, scaling and root planing, maintenance, surgery, or another service.

2. 2

   Which areas and codes are involved?

   Periodontal benefits can apply by mouth, quadrant, tooth, visit, or time period.

3. 3

   Has coverage been verified?

   Ask about active eligibility, frequency, the adult or CAC annual limit, and prior authorization.

4. 4

   What follow-up is recommended?

   Periodontal maintenance and home care are different parts of a plan; follow the treating clinician's individualized instructions.

5. 5

   What changes need urgent help?

   Contact a dental professional promptly for worsening swelling, pus or drainage, severe pain, fever with dental symptoms, or uncontrolled bleeding. Call 911 for trouble breathing or swallowing or rapidly spreading swelling.
