Item Rationale
Quick coding
Answer Codes
Use the item-specific response choices below when structured codes apply.
Response format: Numeric entry
1
Yes on physician-prescribed weight-gain regimen
if the resident has experienced a weight gain of 5% or more in the past 30 days or 10% or more in the
last 180 days, and the weight gain was planned and pursuant to a physician’s order. In
cases where a resident has a weight gain of 5% or more in 30 days or 10% or more in 180
days as a result of any physician ordered diet plan, K0310 can be coded as 1.
2
Yes, not on physician-prescribed weight-gain regimen
if the resident has experienced a weight gain of 5% or more in the past 30 days or 10% or more
in the last 180 days, and the weight gain was not planned and prescribed by a physician.

Coding Guidance
Review what the item asks, how to choose the response, and what should be verified before submission.
Steps for Assessment
This item compares the resident’s weight in the current
observation period with their weight at two snapshots in time:
•
At a point closest to 30 days preceding the current
weight.
•
At a point closest to 180 days preceding the current
weight.
The resident’s weight captured closest to these two time points are the only two weights
considered for this item, but the resident’s weight should be monitored on a continual basis and
weight gain assessed and addressed on the care plan as necessary.
For a New Admission
1. Ask the resident, family, or significant other about weight gain over the past 30 and 180 days.
2. Consult the resident’s physician, review transfer documentation, and compare with admission
weight.
3. If the admission weight is more than the previous weight, calculate the percentage of weight
gain.
4. Complete the same process to determine and calculate weight gain comparing the admission
weight to the weight 30 and 180 days ago.
DEFINITIONS
5% WEIGHT GAIN IN 30
DAYS
Start with the resident’s
weight closest to 30 days ago
and multiply it by 1.05 (or
105%). The resulting figure
represents a 5% gain from
the weight 30 days ago. If the
resident’s current weight is
equal to or more than the
resulting figure, the resident
has gained more than 5%
body weight.
10% WEIGHT GAIN IN
180 DAYS
Start with the resident’s
weight closest to 180 days
ago and multiply it by 1.10 (or
110%). The resulting figure
represents a 10% gain from
the weight 180 days ago. If
the resident’s current weight
is equal to or more than the
resulting figure, the resident
has gained more than 10%
body weight.
K0310: Weight Gain (cont.)
For Subsequent Assessments
1. From the medical record, compare the resident’s weight in the current observation period to
their weight in the observation period 30 days ago.
2. If the current weight is more than the weight in the observation period 30 days ago, calculate
the percentage of weight gain.
3. From the medical record, compare the resident’s weight in the current observation period to
their weight in the observation period 180 days ago.
4. If the current weight is more than the weight in the observation period 180 days ago,
calculate the percentage of weight gain.
Weight Comparison
Coding Instructions
Mathematically round weights as described in Section K0200B before completing the weight
gain calculation.
•
Code 0, no or unknown: if the resident has not experienced weight gain of 5% or
more in the past 30 days or 10% or more in the last 180 days or if information about prior
weight is not available.
•
Code 1, yes on physician-prescribed weight-gain regimen: if the resident
has experienced a weight gain of 5% or more in the past 30 days or 10% or more in the
last 180 days, and the weight gain was planned and pursuant to a physician’s order. In
cases where a resident has a weight gain of 5% or more in 30 days or 10% or more in 180
days as a result of any physician ordered diet plan, K0310 can be coded as 1.
•
Code 2, yes, not on physician-prescribed weight-gain regimen: if the
resident has experienced a weight gain of 5% or more in the past 30 days or 10% or more
in the last 180 days, and the weight gain was not planned and prescribed by a physician.
Coding Tips
•
A resident may experience weight variances in between the snapshot time periods.
Although these require follow up at the time, they are not captured on the MDS.
•
In cases in which multiple weights for the resident may exist during the time period being
evaluated, select the weight on the date closest to the appropriate time point.
•
If the resident is gaining a significant amount of weight, the facility should not wait for
the 30- or 180-day timeframe to address the problem. Weight changes of 5% in 1 month,
7.5% in 3 months, or 10% in 6 months should prompt a thorough assessment of the
resident’s nutritional status.
•
To code K0310 as 1, yes, the expressed goal of the weight gain diet must be documented.
