The safest thing to do is to contact a worker's comp attorney for a FREE consultation. 

If you do insist on completing the forms on your own be sure to do the following; not following a few of these might lead to an investigation of worker's comp fraud.

1.  Report your claim on a timely basis. 

2.  Clearly state the details of  your injury.  If you seem to be fuzzy on details or respond vaguely, there might be questions.

3.  Answer your phone; don't ignore the call and then call back in just a minute.  If this happens once or twice it's okay but if it occurs every time the claimant is called, investigators might think fraud.

4.  Be sure to go to all your medical appts.  Again, there might be reasons for missed appointments; keep in mind though that employees that are truly injured want to get better and back to work asap and rarely miss appts.
