Humana Dental reduced its PPO reimbursement rate for adult prophylaxis (D1110) by 6.1% effective January 1, 2026 — one of the largest single-code rate cuts from any major carrier this year. For a practice billing 30 adult cleanings per week, that's approximately $3,200 in lost annual revenue from a single line item.
The D1110 Rate Cut: What Happened
Humana Dental PPO updated its fee schedule effective January 1, 2026, with D1110 (adult prophylaxis) taking the largest percentage hit. The change reflects Humana's broader strategy of bringing high-volume preventive procedure reimbursements closer to their internal benchmarks — a pattern several major carriers have followed since 2023.
Humana Dental PPO reduced D1110 reimbursement by 6.1% effective January 1, 2026. At 30 adult cleanings per week, this represents approximately $3,200 in annual revenue reduction — before factoring in any impact on D0120 (periodic oral evaluation) if billed on the same date of service.
The reduction follows a pattern Humana established in 2024, when it made similar adjustments to preventive procedure reimbursements in several southeastern markets. In 2026, the adjustment was applied more broadly across Humana's PPO network.

| D0120 | Periodic Oral Evaluation | $38.20 | $37.04 | ▼ −3.0% |
| D2750 | Crown — Porcelain Fused to Metal | $892.00 | $892.00 | No change |
| D4341 | Periodontal Scaling (per quad) | $212.40 | $214.52 | ▲ +1.0% |

Why Humana Targets High-Volume Preventive Codes
Humana's fee schedule strategy for its PPO network has increasingly focused on high-volume, low-complexity preventive procedures — D1110 and D1120 — as cost-control levers. Because these codes are billed at extremely high frequency across the network, even a modest percentage reduction produces significant aggregate savings for the carrier while imposing meaningful revenue loss on individual practices.
The mathematics work against practices that are heavily dependent on Humana PPO patients for their preventive visit revenue. A solo practitioner seeing 30 Humana patients weekly for adult cleanings loses $4.48 per appointment — which compounds to $3,200 annually before considering any D0120 co-reduction on the same visits.
Humana's Renegotiation Window
Humana typically opens its fee schedule renegotiation window for in-network providers in Q3 of each year, with new rates taking effect January 1 of the following year. The 2026 rate changes would have been negotiable during the Q3 2025 window — which most practices didn't know was open.
For 2027 rates, the renegotiation window opens approximately July through September 2026. Practices that want to contest the D1110 reduction or request a fee review for high-volume codes should contact their Humana provider relations representative in Q2 2026 to understand the process and prepare the necessary documentation.
How to Respond to the D1110 Rate Cut
Option 1: Request a Fee Review
Contact Humana provider relations and request a fee schedule review. Come prepared with your volume data — number of D1110 procedures billed quarterly to Humana patients, your UCR fee for D1110, and the fee schedule data from your other major carriers for the same code. Humana has historically been willing to negotiate with practices that demonstrate significant network participation volume.
Option 2: Analyze Network Participation ROI
If Humana patients represent a small percentage of your total patient base, the 6.1% D1110 reduction may be the trigger to evaluate whether continued Humana PPO participation makes financial sense. Calculate your total annual Humana reimbursement against the write-off percentage you're accepting across all codes — not just D1110.
Option 3: Adjust Scheduling Strategy
If dropping Humana participation isn't viable, consider whether your hygiene scheduling can shift Humana patients toward D4341 (periodontal scaling) or other codes where the carrier maintained or improved reimbursement. This requires legitimate clinical justification but is appropriate where patient conditions support it.
