Get Ready for Colorado’s New Workers’ Compensation eBilling Requirements

Starting January 1, 2026, Colorado’s Division of Workers’ Compensation is mandating electronic billing for workers’ compensation medical services. Under CCR § 1101-3, Rule 16-8-1, both providers and payers have new responsibilities to ensure a faster, more secure, and more efficient billing process, and Jopari Solutions is here to help you every step of the way

What the New Colorado Rule Requires

For Providers:

  • Mandatory Electronic Billing: Providers who submit 25 or more workers’ compensation bills per month must send medical bills electronically using HIPAA-compliant transactions (X12 837 format).
  • No Duplicate Paper Submission: If you submit electronically, you may not also submit a paper copy.
  • Timely Filing Rules Remain: Bills must still be submitted within 120 days of service (no change).
  • Exemptions: Providers submitting fewer than 25 workers’ comp bills per month are exempt but are encouraged to adopt eBilling best practices.

For Payers:

  • Mandatory Acceptance of eBills: All payers (excluding self-insured employers) must accept electronic X12 837 (bill) transactions
  • Acknowledgement Requirements: Payers must send an X12 277CA Acknowledgment transaction within 2 business days of receiving an eBill.
  • Remittance Advice Requirements: Payers must issue an X12 835 Electronic Remittance Advice within 30 days of receiving the eBill or within 5 days of issuing payment.
  • Payment Methods: Payers must offer at least one fee-free payment option to providers and disclose any fees if offering options such as electronic funds transfer and or virtual credit cards.
