Having a hard time figuring out why your Medicare claim got returned or rejected? Check out CGS's new web page on "Top Claim Submission Errors (Reason Codes) and How to Resolve." Go to www.cgsmedicare.com/hhh/index.html# and select "Education" from the left side menu, and then select "Educational Materials." For example: Error C7080 occurs when a line item date of service (LIDOS) submitted on a home health claim overlaps a date of service on an inpatient claim, explains CGS, which took over as HHH MAC from Cahaba GBA in June. "CGS encourages you to use the date of the first Medicare billable visit in the episode as the date of service you submit with revenue code 027X or 0623 when billing non-routine or surgical dressing/ wound care supplies," the MAC says. Often "this is the LIDOS that overlaps the inpatient stay." Another example: Hospices receive error 32030 because value code G8 is required when revenue code 0655 (respite) or 656 (general inpatient) is billed on a hospice claim. To resolve this error, check that you included value code G8 if you billed respite or general inpatient care. Then make sure you included the CBSA code as well. "The CBSA must identify the location where the respite or general inpatient (GIP) care was provided," CGS explains.
