Here are some steps you can take when an employer has not filed a claim and you have services to bill.

No claim on file

Follow these steps when an employer has not filed a claim.

Initial visit

  • If assigned, find the injured worker’s claim number via Pinnacol's SelectNet Provider Portal or the customer service team at 303.361.4000 or
  • Determine the injured worker’s (IW) employer name and notify the employer you are treating their IW. Verify the workers’ compensation carrier and when the claim was or will be filed.
  • If no claim number is available, the provider should:
  • Give the IW a completed claim form to submit to the employer,
  • Notify the IW the employer has 10 days to file a claim, and
  • If the employer does not acknowledge a claim within 30 days of services, the IW will be billed.
  • After 30 days, check Pinnacol for a claim number via the provider portal or customer service team. If no claim number is available:
  • Contact the IW to notify them the employer has not filed the claim.
  • The IW can file a claim with the DOWC via WC15 form with the information provided on the claim.

Worker’s Claim for Compensation (WC15)

Form WC15 and instructions can be found on the DOWC website under Forms within "Forms by Number" then, "WC15."

Subsequent visits

Verify the claim number before each visit via the portal or customer service. If no claim number is assigned, continue to bill the IW.

Filing DOWC on behalf of the IW

Providers may file a claim for the IW by completing and submitting a Claim for Compensation form (WC15) as above.

Verifying WC coverage

Visit the DOWC website under Employers, within "Insurance Coverage," then to "Verification of Coverage" or "Self Insurance Permit Listing."

Submitting to the DOWC

Mail or deliver two copies of WC15 to:

The Colorado Division of Workers’ Compensation
Customer Service Unit
633 17th St. Suite 400
Denver, CO 80202-3626
