An F-tag is the tag number CMS assigns to each federal requirement of participation for long-term care facilities under 42 CFR Part 483. When a surveyor finds a facility out of compliance with a requirement, they cite the matching F-tag as a deficiency. Surveyor guidance is in the State Operations Manual, Appendix PP.

What do scope and severity mean for a deficiency?

Every deficiency is rated on scope (isolated, pattern, or widespread) and severity (from no actual harm with potential for minimal harm, up to immediate jeopardy). The two combine into a letter from A to L, which determines how many points the deficiency adds to the health inspection score.

Nursing Home Deficiencies and F-Tags, Explained

The short version

An F-tag is the number CMS assigns to each federal requirement a nursing home has to meet. When a surveyor finds the facility out of compliance, they cite that F-tag as a deficiency. Each deficiency is scored on scope (how many residents it affected) and severity (how much harm), and that score decides how heavily it counts against the facility’s CMS health inspection rating.

What an F-tag actually is

The federal requirements nursing homes must meet live in the regulations at 42 CFR Part 483. CMS gives each requirement a tag number, written with an “F” prefix, so surveyors and facilities can refer to them consistently. When a survey finds a facility is not meeting a requirement, the surveyor writes a deficiency citing that F-tag. The detailed guidance surveyors follow is published in the CMS State Operations Manual, Appendix PP.

How surveyors find them

Deficiencies come from a few kinds of survey:

The standard recertification survey, an unannounced, comprehensive on-site survey.
Complaint investigations prompted by a specific concern.
Focused infection-control surveys.

After a deficiency is cited, the facility submits a plan of correction, and CMS may conduct revisits to confirm the problem was fixed.

Scope and severity: the A to L grid

Every deficiency gets two ratings. Scope is how far the problem reached: isolated (one or a very limited number of residents), a pattern (more than a limited number), or widespread (pervasive or systemic). Severity is how much harm it caused or risked, from no actual harm up to immediate jeopardy (noncompliance that has caused, or is likely to cause, serious injury, harm, impairment, or death).

The two combine into a single letter, A through L, and CMS assigns points by that letter. Lower-harm findings (A through C) carry zero points; immediate jeopardy carries the most:

	Isolated	Pattern	Widespread
Immediate jeopardy	J50 pts	K100 pts	L150 pts
Actual harm	G20 pts	H35 pts	I45 pts
More than minimal harm	D4 pts	E8 pts	F16 pts
Minimal harm	A0 pts	B0 pts	C0 pts

Base points from CMS Five-Star Technical Users’ Guide, Table 1. Deficiencies cited as “substandard quality of care” in certain care areas carry additional points.

How deficiencies feed the Five-Star rating

Those points roll up into the health inspection rating, which is the backbone of the overall CMS Five-Star rating. CMS totals the points across a facility’s two most recent standard surveys plus three years of complaint and focused infection-control surveys, adds points for revisits, weights recent surveys more heavily, and then ranks facilities within their state. So a single serious, widespread citation can move a rating far more than several minor ones.

Some F-tags you will see often

A few of the requirements behind common citations, with their regulation:

F600Freedom from abuse and neglect§483.12

F689Free of accident hazards / adequate supervision§483.25(d)

F686Treatment and services to prevent or heal pressure ulcers§483.25(b)

F880Infection prevention and control§483.80

F656Develop and implement a comprehensive care plan§483.21(b)

F812Food safety requirements§483.60(i)

What people often miss

Not every deficiency moves the rating. A through C findings (no actual harm, potential for minimal harm) carry zero points.
Recent counts more. The most recent survey is weighted more heavily than older ones, so a fresh serious citation hits harder.
Complaints and infection-control surveys count too, not just the annual standard survey.
The rating is in-state. Facilities are ranked against others in the same state, so deficiency-driven ratings are meant for in-state comparison.
