Workers Compensation Claims

Worker Compensation Forms are claims that are filed for people that are injured on the job or develop an illness that is related to their work.

The following help pages are supported by the current version of CollaborateMD. Please follow the curriculum outline to receive the proper training associated with this section.

Processing and submitting Workers Compensation (Workers Comp) and Property & Casualty (P&C) claims has always presented unique challenges. Many require manual processing and the attachment of supporting documentation, which prevents electronic submission. These challenges result in higher costs to the provider, higher rejections and slower reimbursement. 

Assurance Attachments is the solution for submitting Worker’s Comp and P&C claims and their associated attachments efficiently and effectively. By enabling electronic submission, you can use one solution for these specialty claims and bypass the effort and expense of paper processing. This Change Healthcare Assurance Claim Attachment User Guide should be referenced to enable, configure, process claims, follow up and disable the services included with the Claim Attachment feature. There are two methods to choose from when sending attachments: 

Direct Upload

Documents can be uploaded directly to the ChangeAssurance Attachments website


Documents can also be faxed directly to Change Healthcare. A fax cover sheet is downloaded from the ChangeAssurance website which includes a unique barcode which will auto-associate the document to the chosen bill. Faxed attachments can be viewed on the ChangeAssurance Attachment website once scanned into the Change Healthcare system.
