Original data · every stat sourced
The U.S. home health industry — roughly 11,500 Medicare-certified agencies in a market approaching $177 billion — runs on a documentation clock: care initiated within 48 hours, OASIS data spanning 1,026 fields, and visit notes that must reach QA before billing. Below are the late-visit-note statistics we can stand behind, each with its source.
Last reviewed 2026-09-02. Stats without a verifiable source are omitted by policy.
Numbers from Copper AI's live deployment — not projections, not pilot extrapolations. Where a number is not verified, it is not on this page.
3,000+
Completed, human-verified visit notes delivered into WellSky (Kinnser) at Avatar Home Health, a 500+ census Texas home health agency and on-record reference.

500+
Avatar Home Health (Texas) runs Copper AI in production for skilled-nursing visit documentation — not a pilot sandbox.

Hundreds
Each AI-drafted note passes hundreds of automated compliance checks, then human-in-the-loop verification, before it reaches the agency's QA queue.

Copper AI runs on exactly one EMR today — WellSky (Kinnser) — rather than advertising a long list of integrations that are not in production.

Late visit notes are not one agency's bad habit — they are an industry-wide timeliness problem across every Medicare-certified agency in the U.S.
11,500
Every one of them files OASIS assessments and visit notes on the same regulatory clock — documentation timeliness is an industry-wide problem, not an agency-specific one.

$177B
Documentation is the billing gateway for that entire market: a visit that is not documented is a visit that cannot be billed.

CMS sets the timeliness expectations that make a late note expensive: initiation windows, star-rating measures, assessment scope, and effective dates.
48 hours
Home health patients should be seen within 48 hours of referral (or the physician-ordered start date). Timely initiation is one of the seven measures behind CMS quality of patient care star ratings.

Timely initiation of care plus six OASIS- and claims-derived measures — late, inaccurate documentation drags directly on the score agencies show referral sources.

The field count a home health agency has to manage across the OASIS assessment data specifications — the scale that makes manual, late-night charting so error-prone.
