The Ensuring Lasting Smiles Act adds parallel federal requirements to the Public Health Service Act, ERISA, and the Internal Revenue Code that force group health plans, employer-sponsored plans, and health insurance issuers to cover outpatient and inpatient items and services tied to diagnosis and treatment of congenital anomalies or birth defects that primarily affect the appearance or function of the eyes, ears, teeth, mouth, or jaw. The coverage mandate explicitly includes reconstructive surgery, treatment of complications, and adjunctive dental/orthodontic/prosthodontic support from birth until the medical or surgical treatment is complete, while excluding cosmetic surgery that is not medically determined to address such a defect.
The law conditions financial requirements on a parity standard—cost-sharing for these services cannot be more restrictive than the predominant cost-sharing applied to substantially all other medical and surgical benefits in the plan or coverage—and requires plans and issuers to notify enrollees about the benefit beginning January 1, 2026. The bill also orders HHS to study network adequacy and changes in out-of-pocket and procedure costs, with a report due to Congress by December 31, 2027.
For compliance officers and benefits managers, the act creates new mandatory benefits, forces benefit-design coordination with dental carve-outs, and raises near-term questions about provider networks and premium impacts.
At a Glance
What It Does
The bill adds section 2799A–11 to the PHSA and parallel provisions to ERISA and the Internal Revenue Code, requiring coverage of outpatient and inpatient diagnosis and treatment for congenital anomalies primarily affecting eyes, ears, teeth, mouth, or jaw. It specifies covered services—reconstructive procedures, complications, adjunctive dental/orthodontic/prosthodontic support from birth until treatment completion—and limits exclusions to cosmetic procedures not medically related to a defect.
Who It Affects
Applies to health insurance issuers offering individual and group market coverage and to employer-sponsored group health plans (including ERISA plans) and tax-qualified group plans. It directly affects pediatric and craniofacial surgeons, orthodontists, prosthodontists, dental specialists, plan sponsors, and benefits administrators.
Why It Matters
The act closes a common gap where dental and orthodontic components of congenital-care pathways were carved out of medical coverage and left families exposed to high out-of-pocket costs. It forces plans to redesign benefits, reassess provider networks for rare specialty care, and prepare for potential utilization and premium effects.

What This Bill Actually Does
The Ensuring Lasting Smiles Act creates a federal coverage floor for treatment of congenital anomalies that primarily impact facial structures—explicitly listing eyes, ears, teeth, mouth, and jaw. It requires insurers and group plans to pay for both inpatient and outpatient items and services that a treating physician determines are medically necessary to restore function or approximate a normal appearance.
That language covers classic reconstructive surgery, follow-up care for complications, and diagnostic services tied to the underlying congenital condition.
A distinctive feature is the statutory call-out of adjunctive dental, orthodontic, and prosthodontic support from birth through the completion of the surgical or medical treatment pathway. The statute says these dental-related services must be covered "notwithstanding any exclusions, limitations, or restrictions" that would normally prevent dental coverage for conditions caused by other injuries or illnesses.
At the same time, the bill draws a boundary: services purely cosmetic and not provided because of a medical determination of a congenital anomaly remain excluded.Financially, the law does not ban cost-sharing—coinsurance, copays, and deductibles are still allowed—but it sets a parity floor: cost-sharing for covered congenital-care services may not be more restrictive than the plan’s predominant cost-sharing for substantially all other medical and surgical benefits. The text also defers the medical-necessity determination to the treating physician as defined in the Social Security Act, which anchors clinical decisions to the treating clinician’s judgment rather than a plan’s internal rulebook.Operationally, the bill forces a set of immediate actions by plans and issuers: update benefit documents and summary plan descriptions (the bill requires notice to participants starting January 1, 2026), review provider networks for craniofacial teams and pediatric dental specialists, and coordinate benefits where medical and dental plans are separate.
HHS must study network adequacy and the financial impact of the new coverage requirements and report back to Congress by December 31, 2027—meaning the statutory coverage obligations will be in force well before the government issues findings about access and cost effects.
The Five Things You Need to Know
The bill adds PHSA section 2799A–11, ERISA section 726, and IRC section 9826 to require coverage for congenital anomalies primarily affecting eyes, ears, teeth, mouth, or jaw.
It explicitly requires coverage of adjunctive dental, orthodontic, or prosthodontic support from birth until the medical or surgical treatment of the defect is complete, even if plans normally exclude those dental services.
Cost-sharing for these covered services may not be more restrictive than the "predominant" cost-sharing applied to substantially all other medical and surgical benefits in the plan or coverage.
Plans and issuers must provide notice about the required coverage to participants and beneficiaries beginning January 1, 2026, subject to regulations from the Secretary.
HHS must study network adequacy for providers of these services and assess changes in patient out-of-pocket costs and overall procedure costs, with a report due to Congress by December 31, 2027.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Designates the bill as the "Ensuring Lasting Smiles Act." This is procedural but identifies the statute by name for regulatory references and guidance documents that agencies will later issue.
Mandatory coverage standard for individual and group market issuers
Adds a new consumer-protection style requirement in title XXVII of the PHSA that binds health insurance issuers offering individual and group market coverage. It sets an affirmative coverage obligation for diagnosis and treatment of covered congenital anomalies, lists allowed cost-sharing restrictions (subject to the parity floor), defines the scope of covered services (reconstructive, complications, adjunctive dental/orthodontic/prosthodontic support), and provides a narrow exclusion for cosmetic procedures not tied to a medical determination. Plans subject to PHSA will need to alter policy forms and issuer networks to reflect the new benefit.
Coverage obligation for employer-sponsored group health plans
Inserts a parallel coverage mandate into ERISA’s plan rules so that employer-sponsored group health plans must meet the same coverage standard. Because ERISA governs self-funded employer plans, this provision extends the mandate beyond fully insured plans and reduces the risk of coverage gaps where employers had relied on plan carve-outs. Plan administrators will face fiduciary and compliance tasks—revising plan documents, claims protocols, and possibly negotiating adjustments with vendors that manage dental carve-outs.
Tax-code alignment for qualified group health plans
Adds the same substantive requirement to the Internal Revenue Code’s rules for tax-qualified group health plans, which harmonizes tax treatment with the coverage mandate. The insertion ensures that benefits provided to satisfy this mandate will be recognized for tax purposes, closing a potential mismatch where a plan might be required to cover services but face adverse tax treatment for doing so. Employers and plan sponsors should review cafeteria-plan and premium-contribution mechanics in light of the new tax-code language.
HHS study and report on network adequacy and cost impacts
Directs the Secretary of Health and Human Services to study provider networks that supply diagnosis and treatment for the specified congenital anomalies and to assess changes in patient out-of-pocket costs and overall procedure costs attributable to the coverage requirements. The report must be submitted to Congress by December 31, 2027. The study is the bill’s built-in monitoring mechanism, but it comes after the effective date—so findings will be retrospective rather than shaping immediate rollout.
Effective date
States that the amendments to PHSA, ERISA, and the Internal Revenue Code apply with respect to plan years beginning on or after January 1, 2026. That creates a firm compliance deadline for plan years and triggers the notice requirement that the statute requires plans to begin providing as of that date.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Children born with cleft lip, cleft palate, craniofacial microsomia, or related facial congenital anomalies — they and their families will gain guaranteed coverage for reconstructive surgery, orthodontics, prosthodontics, and associated follow-up care that were often out-of-pocket.
- Adults living with untreated or partially treated congenital craniofacial conditions — the statute covers treatment later in life when a treating physician deems it medically necessary, improving access beyond the newborn period.
- Craniofacial surgeons, pediatric plastic surgeons, orthodontists, and prosthodontists — clearer coverage rules reduce reimbursement uncertainty and may increase referrals for multidisciplinary care.
- Families and caregivers — by forcing coverage of dental and orthodontic components tied to congenital defects, the bill reduces a frequent source of catastrophic out-of-pocket spending for long treatment pathways.
Who Bears the Cost
- Health insurance issuers offering group and individual coverage — they face expanded benefit liabilities, higher utilization for multidisciplinary care, and associated administrative costs to update products and networks.
- Self-funded employer plan sponsors and administrators (ERISA plans) — these employers will need to cover benefits previously excluded by carve-outs or dental-only contracts, and they may see increased claims volatility and premium equivalents.
- Standalone dental insurers and dental carve-out vendors — the statute disrupts typical medical-dental boundaries by requiring medical plans to cover dental/orthodontic/prosthodontic care tied to congenital defects, creating coordination and contractual friction.
- Regulatory agencies (HHS, DOL, IRS) — agencies must write regulations, issue guidance, and complete the mandated study and report, imposing administrative and enforcement workload without additional funding in the bill text.
Key Issues
The Core Tension
The bill pits two legitimate goals: guaranteeing comprehensive, multidisciplinary care from birth (including dental and orthodontic components that historically have been excluded) versus containing plan costs and preserving payers’ ability to set evidence-based limits. Ensuring access to complex, often lifelong treatment pathways may raise premiums and administrative burdens; tightening coverage or rigid benefit limits protects affordability but can leave patients with clinically necessary dental and reconstructive needs uninsured. The statute chooses access through mandatory coverage, but it delegates many hard choices—how to measure cost-sharing parity, how to allocate responsibility between medical and dental plans, and how to address limited specialist supply—to regulators, plans, and later litigation.
The bill creates a broad, clinician-centered coverage mandate but leaves several implementation knobs intentionally vague. First, the standard that cost-sharing be "no more restrictive than the predominant cost-sharing" applied to substantially all other medical and surgical benefits requires plans to identify and calculate what constitutes the "predominant" cost-sharing structure across a plan’s myriad benefits—an exercise that will need regulatory clarification and consistent actuarial rules.
Second, the statute entrusts medical necessity to the treating physician as defined by SSA section 1861(r). That deference favors clinicians but may trigger a surge in disputes where payers apply utilization management or second-opinion rules; the bill does not prescribe an appeal timeline or a single adjudicative standard.
A second set of tensions concerns medical–dental carve-outs and network supply. Many employer plans channel dental services through standalone carriers; the statute requires coverage of dental and orthodontic services when tied to the congenital condition "notwithstanding" exclusions, but it does not specify how cost responsibility is allocated across medical and dental contracts.
Absent contractual renegotiation, plans and vendors will face coordination and payment disputes. Meanwhile, craniofacial teams and pediatric dental specialists are geographically concentrated; the HHS study requirement recognizes network adequacy concerns, but the effective date precedes the study.
That gap could force short-term reliance on out-of-network providers, potentially resulting in balance billing and provider reimbursement conflicts.
