MDS Coding Tips of the Month
SECTION GG0170 of the MDS – RAI Manual
GG0170A, Roll left and right
GG0170C, Lying to sitting on side of bed
GG0170A Coding Tip
- If the resident does not sleep in a bed, clinicians should assess bed mobility activities using the alternative furniture on which the resident sleeps (for example, a recliner).
GG0170C Coding Tips
- The activity includes resident transitions from lying on their back to sitting on the side of the bed without back support. The residents’ ability to perform each of the tasks within this activity and how much support the residents require to complete the tasks within this activity is assessed.
- For item GG0170C, Lying to sitting on side of bed, clinical judgment should be used to determine what is considered a “lying” position for a particular resident.
- Back support refers to an object or person providing support for the resident’s back.
- If the qualified clinician determines that bed mobility cannot be assessed because of the degree to which the head of the bed must be elevated because of a medical condition, then code the activities GG0170A, Roll left and right, GG0170B, Sit to lying, and GG0170C, Lying to sitting on side of bed, as 88, Not attempted due to medical condition or safety concern.
