Prevalence of falls (N032.02): the survey measure behind J1800

Any fall coded at J1800 counts, with or without injury, and stays for about a year. How the surveyor-only falls measure works and what counts as a fall.

Most buildings watch falls with major injury, because it’s in Five-Star. CMS also calculates a broader falls measure that counts any fall at all. It isn’t on Care Compare, but it is on the iQIES reports that state surveyors see.

What the measure is, and who sees it

  • CMS ID N032.02, Prevalence of Falls, a long-stay MDS measure.
  • Not on Care Compare, not in Five-Star. It appears on the facility’s iQIES quality measure reports, which are also available to state surveyors.
  • None of the state programs we checked scores it (Ohio, Florida, Texas and New York).
“This measure is a state surveyor measure and is not part of NHQI. As such, it is not reported on Care Compare on Medicare.gov and is only available on the iQIES QM reports.”
MDS 3.0 QM User’s Manual v18.0, Chapter 2, Table 2-32, footnote 34, page 51

What puts a resident in the numerator

One or more assessments in the look-back scan with J1800 = 1: the resident had a fall since admission, entry, reentry or the prior assessment. The injury doesn’t matter here. A fall with no injury counts the same as a fracture.

The only exclusion is a resident whose J1800 is dashed on every assessment in the scan. There is no risk adjustment.

The look-back scan: about a year

Like falls with major injury, this measure reads more than the target assessment. It scans every qualifying assessment (OBRA, PPS 5-Day or OBRA discharge) in the resident’s episode dated up to 275 days before the target. Since J1800 itself covers the time since the prior assessment, the scan reaches back roughly a year.

“These measures trigger if the event or condition of interest occurred any time during a one year period.”
MDS 3.0 QM User’s Manual v18.0, Chapter 1, Section 4, page 9

So a coded fall doesn’t clear on the next assessment. It clears only with time, once the assessment that coded it is more than 275 days older than the resident’s target assessment, or through a modification if the code was wrong.

A worked example. Resident F slips and is caught by an aide in March. The quarterly with a March ARD codes J1800 = 1. Resident F has no more falls. Every target assessment for roughly the next nine months still finds that quarterly in its scan, so Resident F stays in the numerator until a target assessment is dated more than 275 days after it.

What counts as a fall

The RAI Manual’s definition is an unintentional change in position coming to rest on the ground, floor or the next lower surface, such as a bed, chair or bedside mat. It also covers a fall caused by an overwhelming external force, such as being pushed by another resident. A few points trip people up:

  • An intercepted fall is a fall. If the resident would have fallen had they not caught themselves or been caught, code it.
  • Found on the floor means a fall. The RAI Manual assumes a fall occurred when a resident is found on the floor.
  • Falls anywhere count. J1800 includes falls in the hospital or out in the community since the last assessment, not only falls in the building.
  • Balance training in therapy is the exception.
“CMS understands that challenging a resident’s balance and training them to recover from a loss of balance is an intentional therapeutic intervention and does not consider anticipated losses of balance that occur during supervised therapeutic interventions as intercepted falls.”
RAI Manual v1.20.11, Chapter 3, Section J, page J-33

If the resident comes to rest on the floor despite the therapist’s effort to intercept, it is a fall.

New in the October 2026 RAI Manual

Version 1.20.11, effective October 1, 2026, rewrites the J1800 review period. On the first assessment after admission, review the record from the admission date to the ARD. On the first assessment after a reentry, review it from the reentry date (A1600) to the ARD. Otherwise, review all sources for any fall since the last assessment.

Why it’s worth watching

Every fall with major injury is also a fall, so this measure counts every resident the major-injury measure counts, plus residents whose falls caused no major injury. Surveyors can see it. Each J1800 should be backed by the sources the RAI Manual lists: incident reports, fall logs, physician, nursing, therapy and nursing assistant notes, and what the resident and family report.
