Claims and Billing Procedures

Claims must be submitted on a CMS-1500 or UB04 form as appropriate. Per Maryland law, claims must be submitted within 180 days from the date of service. MedStar Family Choice claims should be sent to the following address:

MedStar Family Choice
Claims Processing Center
PO Box 2189
Milwaukee, WI 53201
Phone: 1-800-261-3371


  • Providers have 180 days from the date of a payment retraction to submit a clean and corrected claim for processing. Providers do not have to file a claims appeal for an administrative denial issue if they are within their 180 day timely filing period; a new corrected claim should be resubmitted in this situation.
  • It is important to clearly mark a corrected claim with "corrected claim" boldly and written on the claim.
  • For institutional UB04 claims, the first submission of the claim should never have a bill type XX7. (replacement claim).
  • It is critical for UB04 claims to have CPT/HCPCS codes and units documented, as appropriate.
