Honest Taskers, HomeHealth Advantage, and SimiTree lead this year's shortlist of virtual OASIS documentation assistant companies, seven firms ranked on how they get a home health agency's OASIS assessments accurate and submitted on time, from diagnosis coding and item-by-item review to plan of care checks, discharge reviews, and the documentation chasing that has to happen before a chart can be locked. Two things separate these firms: whether a certified coder reviews every chart, and how many days it takes.
Disclosure: Honest Taskers publishes this list and appears at position 1. We're judged on the same five published criteria as every other company here.

How we chose the best virtual OASIS documentation assistant companies
We ranked these firms on five facts, each read at the provider's own website on August 24, 2026. Those facts are what certification the reviewers hold, published turnaround time, published pricing, whether automation does the first pass, and named compliance. Certification comes first because OASIS scoring drives both the payment and the star rating, and the credentials that signal competence here are specific: HCS-D for diagnosis coding, HCS-O and COS-C for OASIS itself. Turnaround matters almost as much, since a chart sitting in review is a claim not submitted. Two firms publish a turnaround figure and only one publishes a price. Blank facts read "not publicly listed" instead of a guess.
Best virtual OASIS documentation assistant companies compared
The table ranks all 7 on the same columns, Honest Taskers first because we publish the list. Facts were read August 24, 2026 and change often, so treat them as a starting point, not a quote.
| Company | What it does | Certification stated | Published pricing | Turnaround / model | Compliance named |
|---|---|---|---|---|---|
| Honest Taskers | Administrative support around the assessment: visit scheduling, chasing missing documentation, submission deadline tracking, ADR follow-up | None claimed for OASIS scoring; pool includes licensed nurses and physicians | $10.00–$12.65/hr | Staffing by the hour | Compliance officer; HIPAA compliance verified by Accountable; BAA when PHI is accessed |
| HomeHealth Advantage | OASIS review and diagnosis coding, chart audit and QA included | All reviewers licensed RNs plus certified home health coders and certified OASIS specialists (HCS-D, COS-C or equivalent), minimum 10 years experience | Coding from $35; OASIS review and coding from $55, volume discounts | 1 to 2 business days, human review | HIPAA Business Associate Agreement required |
| SimiTree | ICD-10 coding, OASIS review, plan of care review, discharge reviews, education; full post-acute RCM alongside | Not publicly listed | Not publicly listed | 48 hours standard; AI-assisted coding suggests codes from documentation | Not publicly listed on the pages read |
| Healthcare Provider Solutions | Home health and hospice coding, OASIS review, billing, clinical and operations compliance consulting | Home health coders hold HCS-D, hospice coders HCS-D and HCS-H (company-stated); named staff RN, HCS-D, COS-C | Not publicly listed | Not publicly listed; 100% US-based support | "HIPAA Compliant & Secure"; CHAP and ACHC certified |

| Axxess | Home health software with OASIS management, alerts for missing items, and an OASIS scrubber | Not applicable; your clinicians complete the assessment | Not publicly listed | Software; 10,000+ organizations on the platform | Not publicly listed on the pages read |
One firm publishes a per-chart price and a turnaround commitment and names the credentials its reviewers hold, which is more transparency than the rest of this category offers combined. Two firms put automation in front of the human review, which is a legitimate model and a sharply different product from a certified coder reading every chart. And one entry is software that argues you should not be outsourcing this at all, which is worth hearing before you sign anything.
1. Honest Taskers
Best for: agencies whose OASIS bottleneck is missing documentation and clinician chasing rather than the scoring itself.
Pricing: $10.00–$12.65/hrLocation: US clients; PH, LatAm, India and Pakistan recruitingModel: Staffing by the hourFirst hire: Two-week working trial
Look closely at where OASIS charts stall and most of it is not clinical judgement. A visit note is missing, a physician order has not come back, the medication list disagrees with the discharge summary, a clinician has three assessments outstanding and nobody is chasing them, and the five-day submission window is closing. Honest Taskers places staff who work inside your electronic health record on exactly that layer: scheduling and confirming assessment visits, chasing outstanding documentation and orders, tracking which charts are approaching their submission deadline, assembling records for additional documentation requests, and keeping the queue visible so your certified reviewers spend their time reviewing rather than hunting. Staff are trained on HIPAA and data privacy under a dedicated compliance officer, work in your time zone, and a Business Associate Agreement is signed before anyone touches protected health information, with HIPAA compliance verified by Accountable. The talent pool includes licensed nurses and physicians. Rates run about $10 to $12.65 an hour by role, background, schedule, and location, with a two-week working trial on the first hire and 99.6% average monthly retention reported. See the multi-purpose virtual medical assistant service for role detail.
Limitation: the firm claims no HCS-D, HCS-O, or COS-C certification, so OASIS scoring and diagnosis coding stay with your certified reviewers or an outsourced coding partner, and this covers the work around the assessment rather than the assessment itself.
2. HomeHealth Advantage
Best for: agencies that want a certified US-based RN reviewing every chart, at a published per-chart price, inside two days.
Pricing: From $35 coding, $55 OASIS plus codingLocation: All reviewers US-basedModel: Per chart, human reviewTurnaround: 1 to 2 business days
HomeHealth Advantage is the most transparent firm in this category by a wide margin, and transparency is worth ranking for when everyone else quotes on request. Coding starts at $35 and OASIS review with coding starts at $55, with volume discounts, so you can calculate the cost of outsourcing before a sales call. Standard turnaround is one to two business days, stated bluntly as "for real". Every reviewer is a licensed RN who is also a certified home health coder and a certified OASIS specialist holding HCS-D, COS-C, or equivalent, with a minimum of ten years of home health nursing and coding experience, and all reviewers are based in the United States. A HIPAA Business Associate Agreement is required. The company states it has never had a claim denial from its coding or OASIS recommendations in over five years, and reports around $300 in additional Medicare revenue per episode.
Limitation: the OASIS review service is home health only, with hospice limited to diagnosis coding, and the site names no SOC 2 or other audited security certification beyond the BAA.
3. SimiTree
Best for: agencies that want coding and OASIS review from a firm that can also take on billing, cost reporting, and recruiting.
Pricing: Not publicly listedLocation: Hamden, ConnecticutModel: AI-assisted coding with reviewTurnaround: 48 hours standard
SimiTree is the scale option, and the breadth is the reason to consider it. Coding and OASIS review sit alongside revenue cycle management, billing, compliance and regulatory risk work, cost reporting, credentialing and contracting, data analysis, and interim leadership recruiting, across home health, hospice, and behavioral health. The review service covers ICD-10 coding, OASIS review, plan of care review, discharge reviews, and customised education, with a stated 98% accuracy rate and a 48-hour standard turnaround. Its coding is AI-assisted, with the technology suggesting codes from the documentation. Company-reported scale figures are 1,200 or more industry experts, 16,000 or more agencies served, and 750 or more active clients.
Limitation: it names no coder certifications at all on the pages we read, which is a notable omission in a credential-driven category, and neither pricing nor any compliance certification is published.
4. Healthcare Provider Solutions
Best for: agencies that want certified coders and an accredited firm, with billing available under the same roof.
Pricing: Not publicly listedLocation: 100% US-based supportModel: Per chart plus consultingExperience: 25 years, 130+ agencies
Healthcare Provider Solutions has been doing this for over 25 years, supports more than 130 agencies, works across 15 or more electronic medical record systems, and states that its support is entirely US-based. It states that home health coders hold HCS-D certification and hospice coders hold both HCS-D and HCS-H, and its named staff carry RN, HCS-D, and COS-C credentials. Home health and hospice coding sit alongside OASIS review, billing for both settings, revenue cycle consulting, managed care contracting and credentialing, clinical and operations compliance, and medical review consulting. It describes itself as HIPAA compliant and secure and holds CHAP and ACHC certification, and it offers a free coding and OASIS review so you can test the work before committing.
Limitation: no pricing, no turnaround figure, and no SOC 2 or equivalent audited certification appear on the site, so the operational commitments have to be extracted in a call.
5. HealthRev Partners
Best for: agencies that want review plus clinician coaching, so the same errors stop recurring.
Pricing: Not publicly listedLocation: United StatesModel: Tiered review scopesExtras: Preceptor programs
HealthRev Partners is the teaching option, and on a team with clinician turnover that changes the economics. It offers graduated scopes, Coding Only, Coding Plus, OASIS Review, OASIS Plus, Plan of Care Review, and Discharge Review, so you buy the depth you need rather than one package. Reviews are performed by dual-certified professionals described as certified RNs and certified coding experts, with live clinician guidance available by telephone conference and an option for the firm to enter data into your electronic health record. It also runs an eight-week new-hire preceptor program and a six-week live OASIS refresher, which is aimed at fixing the source of the errors rather than only correcting them.
Limitation: it publishes no turnaround figure, no accuracy figure, no pricing, and no compliance statement, so every operational commitment needs to come out of the contract discussion.
6. SelectData
Best for: high-volume operators willing to trade certified human review for same-day throughput.
Pricing: Not publicly listedLocation: Not publicly listedModel: Automation-led, reviewer overrideTurnaround: Same-day output
SelectData has rebuilt itself around automation, and the honest way to describe its SmartCare product is as a scoring engine with a human override rather than a coding service. It performs OASIS automation and scoring, ICD-10 coding, and quality assurance aimed at reducing rework, and produces what it calls audit-ready rationale with source citations and reviewer override. It reports better than 80% exact match and better than 93% expert match against human coders, a 3% to 6% reimbursement uplift, and claims SmartCare outperformed human review by 12% to 36%. The commercial argument is throughput: it compresses a three to five day review cycle into same-day output. Its own framing of the problem is useful too, citing 57 or more minutes per OASIS assessment per clinician and two or more full-time equivalents consumed by OASIS completion.
Limitation: it is home health only with no hospice offering, names no coder credentials, pricing, delivery location, or compliance position, and puts automation ahead of certified human review, so verify how override works on your charts.
7. Axxess
Best for: agencies whose OASIS errors come from weak software prompts rather than weak reviewers.
Pricing: Not publicly listedLocation: Not publicly listedModel: Software platformScale: 10,000+ organizations
Axxess is on this list because it makes the argument against everything above it, and that argument deserves a hearing. Its position is that with the right home health software an agency should not have to outsource time-consuming documentation tasks like OASIS and diagnosis code reporting. The platform provides OASIS management with step-by-step instructions and alerts for missing required information, includes updated diagnosis codes with descriptions, and offers an OASIS scrubber that audits assessments for clinical inconsistencies, coding inconsistencies, fatal audits, and CMS warnings before submission. More than 10,000 organizations use the platform, and it runs a module-based certification program for staff and leadership.
Limitation: it is software, so your own clinicians still complete every assessment and act on every scrubber warning, which does not help an agency whose problem is that it has nobody qualified to review.
Should OASIS review go to an assistant, in-house staff, or software?
Outsource the review when you do not have a certified reviewer, which is the situation for most agencies below a certain size. HCS-D and COS-C credentials are not common, a single reviewer creates a single point of failure, and at $35 to $55 a chart the outsourced price is legible in a way a salary is not. Staff the surrounding work either way, because the chasing, scheduling, deadline tracking, and additional documentation request assembly are administrative and they are what delay submission. A medical records specialist earned about $51,140 a year, roughly $24.59 an hour before benefits, according to the U.S. Bureau of Labor Statistics May 2025 wage data for medical records specialists, against roughly $10 to $13 an hour for placed remote staff. Fix it in software when your reviewers are competent but your prompts are not, and the errors are omissions rather than judgement calls. The three are not exclusive, and most agencies end up with software prompts, outsourced certified review, and administrative staff keeping the queue moving. For the administrative scope, see tasks to outsource to a virtual medical assistant.
What are the risks of outsourcing OASIS review to an assistant?
OASIS drives payment and star ratings simultaneously, so an error costs money twice and the agency owns both.
- Who signs the assessment. A reviewer recommends; your clinician remains responsible for the submitted assessment. Confirm the workflow puts a clinician on the final answer.
- Upcoding pressure. Be wary of a firm selling reimbursement uplift as its headline. Ask how it documents that a higher acuity was supported rather than asserted.
- Automation without disclosure. Establish whether a certified human reads every chart or only the ones the engine flags, and get it in writing.
- Turnaround against the submission window. Match the promised turnaround to your own lock and submission deadlines, including weekends.
- Compliance evidence. Only two of these seven name any compliance position at all. Get the Business Associate Agreement before charts move.
How is an OASIS review assistant priced?
Per chart, mostly, and this is the one category on our site where a provider publishes the number. HomeHealth Advantage states coding from $35 and OASIS review with coding from $55, with volume discounts, which gives you an anchor for every other quote. SimiTree, Healthcare Provider Solutions, HealthRev Partners, and SelectData are all quote-only, and Axxess licenses software rather than charging per chart. Honest Taskers publishes $10.00 to $12.65 an hour for administrative staffing, which converts to a per-chart figure once you know how many charts an hour of chasing supports. The useful comparison is total cost per episode: the review fee plus the administrative labor plus the cost of a delayed claim. Ask each provider what happens when a chart needs a second pass, since rework is where per-chart pricing quietly stops being per chart. Rates were checked August 2026 and change often. For staffing rate context, see how much a virtual medical assistant costs in 2026.
What should you look for in an OASIS review assistant?
Certification, turnaround, automation disclosure, and price per chart including rework.
- Named credentials. Ask for HCS-D, HCS-O, or COS-C by name and whether every reviewer holds them. Two firms here answer that unprompted.
- A turnaround number, not an adjective. "Rapid" is not a commitment. One to two business days and 48 hours are.
- How much of the review is automated. Get the human review scope in writing, and more so with automation-led providers.
- Per-chart price including rework. Ask what a second pass costs and who decides one is needed.
- Education included or not. A firm that teaches your clinicians reduces next quarter's error rate, which is worth more than a discount.
How do you hand OASIS review to an assistant?
Start by finding out whether your problem is scoring accuracy or submission delay, because they have different fixes.
- Audit one month of assessments for both error rate and days from visit to submission.
- If accuracy is the issue, take a free or paid trial review from two certified providers on the same charts and compare.
- If delay is the issue, staff the chasing and deadline tracking before changing reviewers.
- Get the Business Associate Agreement and confirm who signs the final assessment.
- Run a bounded pilot, measure error rate, turnaround, and cost per episode, then expand.

Methodology and sources
We read each company's own website on August 24, 2026, recording reviewer certifications, published turnaround, published pricing, whether automation performs the first pass, and named compliance. Wage context is from the U.S. Bureau of Labor Statistics May 2025 Occupational Employment and Wage Statistics for medical records specialists. OASIS submission requirements and the home health payment model are set by the Centers for Medicare and Medicaid Services. Where a company didn't publish a fact, we marked it "not publicly listed"; accuracy, match-rate, and revenue figures are labeled company-reported and were not independently audited.

If the delay is administrative rather than clinical, the fastest improvement is usually deadline tracking and documentation chasing. Our explainer on what a virtual medical assistant is covers the scope a remote hire can own around an assessment, and where the line sits before work requires a coding or OASIS credential.
