Somebody reads the OASIS against the visit note. Somebody checks the diagnosis codes, confirms the plan of care lines up, and catches what Medicare will ask about later. Every chart, before it bills.
The open questions are who does that reading, how fast it happens, and what it costs you the month census jumps or that person is out.
"Always playing catch-up even on the basics." That is how one customer described the review. Another described the specialist every agency leans on: "Taking off work is crippling. That person is super specialized and has a wealth of knowledge."
Three ways to get the chart read
In-house. Your own coder or QA reviewer reads every chart, page by page. Usually one person, sometimes a nurse who does other things too. The work stays inside the agency and so does the knowledge.
Outsourced. A coding company reads your charts for a fee per chart. Certified coders, a turnaround promise, a contract. The charts leave the building and come back coded.
Automated. Software does the first read on every chart and hands your team the ones that need a person. Enzo QA checks diagnosis codes, comorbidities, OASIS responses, plan of care alignment and compliance risks before anyone opens the chart, then flags what needs attention with a plain explanation of why. Your coder confirms, adjusts or overrides. Other systems do a version of this.
The differences show up when volume moves
- Who reads the chart first. In-house: Your coder, page by page. Outsourced: A vendor's coder, page by page. Automated: The software, every chart, before anyone opens it.
- Who makes the final call. In-house: Your coder. Outsourced: Their coder, then your sign-off. Automated: Your coder, on the flags.
- Turnaround. In-house: One person's queue. Outsourced: Their contract terms. Automated: Charts do not wait in a queue.
- How the cost behaves. In-house: A salary, flat until you need a second one. Outsourced: Per chart, so it rises with census. Automated: A subscription, flat as volume grows.
- When census grows. In-house: Hire, or the queue grows. Outsourced: The invoice grows. Automated: The same team reviews more charts.
- When the reviewer is out. In-house: The queue stops. Outsourced: Unaffected. Automated: Unaffected.
- Audit trail. In-house: Whatever your process records. Outsourced: Whatever the vendor returns. Automated: Every flag, review and approval documented.
- OASIS and ICD-10 changes. In-house: Your person's training time. Outsourced: The vendor's job. Automated: The system's job, your team confirms.
Which one fits your agency?
Stay in-house if your census is steady, your coder has capacity, and audits have not been a problem. The cost is known and the control is total. The risk is the day that person is out, or the month census jumps.
Outsource if you are short-staffed today, your audit exposure is real, or you need certified coding you do not have in the building. You buy expertise and a turnaround promise. The fee rises with every chart, the coder does not know your clinicians, and your team still reviews what comes back.
Automate if the review is the bottleneck. Charts waiting days. A coder who cannot keep up with census. A QA backlog that grows every time you add a nurse. An outsourcing invoice you have started to notice.
If two of those describe you, price each one in dollars or in days of delay and let the bigger number decide.
Enzo handles the volume. Your team owns the outcome.
Enzo QA reads every chart before submission. What passes keeps moving. What does not reaches your coders and clinical reviewers flagged, with a plain explanation of what needs attention and why. They confirm, adjust or override before it submits.
Every flag, every review and every approval is documented with a full trail. If Medicare questions a chart later, the answer is already there.
Enzo QA is trained on the coding standards that determine your reimbursement, HCC and ICD-10, and on home health documentation specifically. Not general medical coding.
It is also part of an AI native EHR, not a layer bolted onto one. When Enzo Scribe captures the visit, the chart arrives with the clinical detail already in it. Fewer gaps to flag, fewer queries to chase. For agencies not ready to change systems, QA connects directly to the EHR you already run. For agencies outsourcing coding today, it reduces that dependency or ends it. See QA in action.
What a complete chart is worth
$200 or more per patient, per episode. Agencies using Enzo are capturing more of the reimbursements they are owed, based on early customer results.
Seven questions to ask any of the three
- Who reads the chart first, and who makes the final call?
- What is the turnaround when census is 20 percent higher than today?
- What happens the week the reviewer is out?
- How does the cost move when volume moves?
- Where is the record of what was flagged and what was decided?
- How does the option stay current when OASIS or ICD-10 changes?
- Can you show one real chart going through, start to finish, with a mistake in it?
The last question is the evaluation. A clean demo tells you nothing.
Frequently asked questions
What is an OASIS scrubber?
Software that checks an OASIS assessment for item logic conflicts, missing data and responses that do not match the rest of the chart. Automated QA does that and reviews the diagnosis coding and the plan of care against the visit documentation.
Should you outsource OASIS coding or use software?
It depends on where the review breaks today. Outsourcing buys certified coders and a turnaround promise at a per-chart fee. Software reads every chart first and leaves the judgment calls to your team at a fixed cost. Agencies whose bottleneck is volume tend to automate. Agencies whose gap is expertise tend to outsource, at least at first.
Can software replace your coder?
Not the judgment. Automated QA does the first read and flags what needs attention. Your coder confirms, adjusts or overrides. The reading changes. The deciding does not.
Does automated QA work with your current EHR?
Enzo QA connects directly with the system you already run. Agencies that are not ready to change EHRs run it alongside what they have.
What does outsourced coding cost?
Coding companies price per chart and quote by volume, so the number depends on your census. Ask for the per-chart rate and the turnaround commitment together. One without the other is half a quote.
