How to score it

Assess the patient's ability to move from sitting on the side of the bed to lying flat on the bed, or on their preferred/necessary sleeping surface if they don't sleep in a bed. If the clinician determines bed mobility can't be assessed because the head of the bed must stay elevated for the patient's medical condition, use the appropriate activity-not-attempted code (07/09/10/88) instead of the 6-point scale. See Guidance Manual Ch. 3 GG item-by-item tips for full scoring rubric.

The common error

Assuming the item can't be assessed simply because the patient doesn't use a standard bed — CMS directs the clinician to assess the sit-to-lying transition on whatever surface is the patient's preferred or necessary sleeping surface, not to default to a not-attempted code.
