6.3 Workers' Comp Claims Adjusting & Return-to-Work

Key Takeaways

  • Upon receiving Form 30C, adjusters must pay or file Form 43 within 28 calendar days under C.G.S. § 31-294c; failure to respond creates a conclusive presumption of compensability.
  • Maximum Medical Improvement (MMI) marks the point where no further structural recovery is anticipated, ending TTD and triggering PPD impairment rating evaluations.
  • Form 36 must be filed with the Commission and employee before an insurer can legally discontinue or reduce TTD or TPD indemnity payments.
  • Employers Liability (Coverage B) protects employers against common-law tort claims not covered by statutory Workers' Comp (Coverage A), including third-party over actions and loss of consortium.
  • Medicare Secondary Payer (MSP) compliance mandates Workers' Compensation Medicare Set-Asides (WCMSAs) when settling future medical care for Medicare beneficiaries ($25,000 threshold) or expected beneficiaries ($250,000 threshold).

6.3 Workers' Comp Claims Adjusting & Return-to-Work

Claims adjusting in workers' compensation requires strict compliance with statutory deadlines, medical management protocols, return-to-work (RTW) strategies, and federal regulatory mandates. A single administrative oversight can result in severe financial penalties or complete preclusion of employer defenses.


Statutory Claims Administration & Critical Forms

Connecticut workers' compensation claims are administered through standardized statutory forms issued by the Workers' Compensation Commission:

Form 30C (Employee's Notice of Claim)

  • Filed by the injured employee to provide formal written notice of a claim for compensation.
  • Triggers the employer's and adjuster's statutory duty to respond.

Form 43 (Notice to Controvert / Intention to Contest Liability)

  • The 28-Day Rule (C.G.S. § 31-294c): Upon receiving Form 30C, the insurer/adjuster has 28 calendar days to either:
    1. Pay indemnity and medical benefits without prejudice; OR
    2. File Form 43 contesting liability, specifying the exact legal and factual grounds for denial.
  • Conclusive Presumption of Liability: If the insurer fails to file Form 43 or commence benefit payments within 28 days, the employer is precluded from contesting compensability or raising defenses regarding liability!

Form 36 (Notice of Intention to Discontinue or Reduce Payments)

  • Insurers cannot unilaterally stop or reduce TTD or TPD indemnity payments.
  • The adjuster must file Form 36 accompanied by supporting medical evidence (e.g., physician work release or MMI report).
  • The employee has 15 days to object. Payments must continue until an ALJ reviews the filing at an informal hearing.

Medical Management: MMI, IMEs, and Return-to-Work

Effective claims management relies on objective medical evaluations and structured return-to-work initiatives:

Maximum Medical Improvement (MMI)

  • Definition: MMI is reached when an injured worker's condition has stabilized and no further functional improvement or structural recovery is anticipated despite continued medical care.
  • Significance: Reaching MMI ends Temporary Total Disability (TTD) benefits and triggers evaluation for Permanent Partial Disability (PPD) ratings.

Independent Medical Examinations (IMEs - C.G.S. § 31-294f)

  • Under C.G.S. § 31-294f, the employer/insurer has the statutory right to request an Independent Medical Examination (IME) performed by a physician of their choosing.
  • If an employee unreasonably refuses to submit to an IME, their right to ongoing disability benefits is suspended during the period of refusal.

Return-to-Work (RTW) & Vocational Rehabilitation

  • Employers are strongly encouraged to offer light-duty or modified-duty job placements within the physical restrictions established by the attending physician.
  • If an employer offers suitable light-duty work within restrictions and the employee refuses without good cause, TTD/TPD benefits may be terminated.
  • The State Workers' Compensation Commission Rehabilitation Services provides vocational retraining, job placement, and educational programs for workers unable to return to their former occupation.

Employers Liability Insurance (Coverage B)

A standard Workers' Compensation policy consists of two distinct coverage parts:

  • Coverage A (Statutory Workers' Compensation): Pays mandatory statutory benefits under state law without policy dollar limits.
  • Coverage B (Employers Liability Insurance): Protects the employer against common-law bodily injury lawsuits brought by employees that fall outside statutory workers' compensation.

Four Standard Employers Liability Claim Scenarios:

Claim TypeDescription
Third-Party Over ActionAn injured worker sues an equipment manufacturer (third party). The manufacturer then sues the employer alleging employer negligence contributed to the injury.
Dual Capacity ActionThe employee sues the employer in a non-employer capacity (e.g., employer manufactured a defective product that injured the worker).
Consequential Bodily InjuryA spouse or family member suffers physical illness or mental breakdown as a direct consequence of the employee's severe injury.
Loss of Services / ConsortiumA spouse sues the employer for loss of marital fellowship and services resulting from a workplace injury.

Standard Limits: Employers Liability policies carry standard split limits of $100,000 Bodily Injury by Accident (per accident) / $500,000 Bodily Injury by Disease (policy limit) / $100,000 Bodily Injury by Disease (per employee).


Federal Compliance: Medicare Secondary Payer (MSP) & WCMSAs

When settling workers' compensation claims that include future medical care, adjusters must strictly comply with the federal Medicare Secondary Payer (MSP) statute (42 U.S.C. § 1395y).

Under MSP laws, Medicare is a secondary payer to workers' compensation. Settling parties cannot shift future medical expenses onto Medicare. To protect Medicare's interests, parties establish a Workers' Compensation Medicare Set-Aside (WCMSA) arrangement.

CMS Review Thresholds for WCMSAs:

  • Threshold 1: The claimant is currently a Medicare beneficiary, and the total gross settlement amount exceeds $25,000.
  • Threshold 2: The claimant has a reasonable expectation of Medicare enrollment within 30 months of settlement (e.g., 62+ years old or applied for Social Security Disability), and the total gross settlement exceeds $250,000.

Funds allocated to a WCMSA must be used exclusively for injury-related medical care that would otherwise be covered by Medicare until the set-aside funds are fully exhausted.
