Coverage Criteria for CMS-1500 Line Reporting
Coverage Criteria — Criteria for processing CMS-1500 claim lines when 'from' and 'to' dates span multiple days
UnitedHealthcare Medicare Advantage follows NUCC and CMS guidance when processing CMS-1500 claim lines that report a 'from' and 'to' date span greater than one day. Claims will be processed only when the reporting meets the rules below.
ALL of the following
- When reporting a range with distinct 'from' and 'to' dates that span more than one day, the number of units (column 24G 'Days or Units') must correspond to the number of days in the date span or be equally divisible by that number of days.
If units do not correspond or are not equally divisible by the number of days, the claim line will not be processed; services must be resubmitted on separate lines with matching dates and units.
- Grouping (reporting a single line with a multi-day 'from'/'to' span) is allowed only when place of service, procedure code, charges, and individual provider are identical for each day in the span.
Grouping is limited to identical services on consecutive days per NUCC guidance.
