Chiropractic EHR software looks simple from the outside: a short visit, a few spinal levels, one of three manipulation codes. The hard part is that Medicare pays for chiropractic care under narrow rules, and the chart has to prove each rule was met on every visit.
This guide is for founders and product leaders building or replacing a chiropractic record system. It covers what Medicare actually covers, how PART findings and the subluxation level shape the note, how the AT modifier decision should work in software, and where chiropractic documentation tends to fail an audit.
What is chiropractic EHR software?
Building a chiropractic record system?
Agnotic designs and builds chiropractic EHRs for clinics and software companies, with exam, note and claim logic shaped by payer documentation rules.
Chiropractic EHR software is a clinical record built for spinal care: it captures the history, the examination findings that show a subluxation, the spinal levels treated and the treatment plan, then turns each visit into a claim. For Medicare patients it must also record whether care is active or maintenance, which decides payment.
A general ambulatory EHR can store a chiropractic note as free text. What it usually cannot do is check that the note contains the specific elements a payer reviewer looks for, or link the level named in the diagnosis to the level manipulated that day.
What does Medicare cover for chiropractors?
Medicare covers one chiropractic service: manual manipulation of the spine to correct a subluxation. Under 42 CFR 410.21(b), Part B pays for a chiropractor's manual manipulation of the spine only when the subluxation has resulted in a neuromusculoskeletal condition for which that treatment is appropriate.
The same regulation says Part B does not pay for X-rays or other diagnostic or therapeutic services furnished or ordered by a chiropractor. That has direct consequences for the software:
- Billable codes: For Medicare, the claim lines that matter are the spinal manipulation codes 98940 (one to two regions), 98941 (three to four regions) and 98942 (five regions).
- Non-covered services: Extremity adjustments, therapies and exams can still be documented and billed to other payers or to the patient, but the system should mark them as not payable by Medicare.
- Advance notices: When the patient will pay for a non-covered service, the workflow should prompt for the right beneficiary notice before the service, not after the denial.
- Payer rules by plan: Commercial and Medicare Advantage plans often add their own visit limits and authorization rules, so the rule set must be configurable per payer.
How should the exam record a subluxation?
The exam should record a subluxation either by imaging or by structured physical findings. Chapter 15, section 240.1.2 of the Medicare Benefit Policy Manual allows both routes and sets clear criteria for each.
For imaging, the manual treats an X-ray as reasonably proximate if it was taken no more than 12 months before or 3 months after the start of a course of treatment, with exceptions for long-standing conditions such as scoliosis. A previous CT or MRI that shows the subluxation is also acceptable evidence.
For physical examination, the manual lists four findings, often remembered as PART, and requires two of them, one of which must be asymmetry or a range of motion abnormality:
- Pain or tenderness: Location, quality and intensity, recorded against a spinal level rather than as a general complaint.
- Asymmetry or misalignment: Identified at a sectional or segmental level.
- Range of motion abnormality: Changes in active, passive or accessory joint movement, increased or decreased.
- Tissue or tone changes: Changes in the skin, fascia, muscle or ligament around the segment.
Software can enforce the two-of-four rule as a structured check. If the clinician records only pain and tissue changes, the note is missing a qualifying finding, and the system should say so before the visit is signed, not leave the gap for a reviewer to find months later.
Why does the subluxation level matter so much?
The subluxation level matters because Medicare requires the chiropractor to state the precise level to support a claim, and the primary diagnosis must be subluxation at that level. A note that says "low back pain" without naming a segment does not support manipulation of the spine.
The manual also asks that symptoms bear a direct relationship to the level cited. A cervical subluxation explains headaches or arm symptoms; it does not explain foot numbness. This is a place where good design helps the clinician rather than slowing them down.
- Level picker: A spine diagram or list of segments from occiput to sacrum and pelvis, so levels are coded consistently instead of typed.
- Diagnosis link: The diagnosis list is filtered to codes that match the selected levels, and the primary diagnosis is set from them.
- Region count: The number of distinct regions treated is calculated from the levels, which then suggests 98940, 98941 or 98942.
- Symptom check: Symptoms entered in the history are tagged to regions, and a mismatch with the treated levels raises a soft warning.
When should the AT modifier be applied?
The AT modifier should be applied only when the visit is active or corrective treatment of an acute or chronic subluxation. CMS requires AT on claims for 98940, 98941 and 98942 to pay them, and treats a claim without AT as maintenance therapy, which Medicare denies.
CMS is equally clear that AT does not prove the service was reasonable and necessary. A contractor can still deny the claim on review if the record does not show active treatment. So the software should not add AT automatically to every Medicare visit, which is a common shortcut. It should derive the modifier from the record.
- Treatment plan present: The plan states the recommended frequency and duration of visits, specific goals and objective measures, as section 240.1.2 asks for at the initial visit.
- Measured progress: Each subsequent visit records a change in condition since the last visit and an evaluation of treatment effectiveness.
- Improvement expected: The clinician confirms that further functional improvement is still expected. When the condition has stabilized, care becomes maintenance.
- Plan review date: When the plan's end date passes, the system asks for a re-examination before AT can be applied again.
When the clinician marks a visit as maintenance, the claim goes out without AT, and the front desk should already hold a signed notice if the patient is paying. The decision belongs to the clinician; the software records it and makes the claim match.
What does a chiropractic visit note need?
A chiropractic visit note needs the history, the exam of the treated area, the treatment given that day and an assessment of change. Most clinics write these as SOAP notes, and the structure maps well onto the Medicare elements.
- Subjective: Chief complaint, changes since the last visit, pain scores and any new symptoms, linked to regions.
- Objective: PART findings by level, range of motion measurements and any outcome questionnaire scores.
- Assessment: Whether the patient is improving, stable or worse, against the goals in the treatment plan.
- Plan: Levels manipulated, technique, other services given, and the next visit or re-examination date.
Speed matters in a chiropractic clinic, where a provider may see many short visits a day. Carry-forward of the previous visit's findings saves time, but it is also the most common source of cloned notes. A safer pattern is to carry forward the structure and the levels, and require the clinician to confirm or change each finding before signing.
Where do chiropractic records fail review?
Chiropractic records fail review when the note does not show why active treatment was needed on that date. The failure points below follow from the Medicare documentation rules above and from how clinic systems generate notes and claims.
- Cloned notes: Identical findings across many visits suggest no change and no active treatment, even when the patient was improving.
- Missing level: The diagnosis names a region, but the note never states the specific segment.
- One PART finding: Pain is documented, but asymmetry or a range of motion abnormality is not.
- Stale imaging: An X-ray used as evidence falls outside the proximity window and no exam findings back it up.
- Blanket AT: The modifier is set by default for every Medicare visit, including maintenance care.
- Expired plan: Visits continue past the plan's end date without a re-examination or new goals.
Each of these can be caught by a rule that runs at sign time. The rules should warn and explain, and the clinician should be able to override with a reason that is stored with the note.
Should a clinic buy or build a chiropractic EHR?
Most single clinics should buy a chiropractic EHR that already handles these rules, and spend their effort on configuration. Building makes sense for a chiropractic group, a multi-specialty practice that adds chiropractic care, or a software company that wants to own the product.
- Group with many sites: A custom system can enforce one documentation standard and report outcomes across clinics.
- Multi-specialty practice: Chiropractic notes can sit beside physical therapy and primary care in one record instead of a separate system.
- Software company: Owning the rule engine, the claim logic and the patient app is the product itself.
- Integration-heavy clinic: Imaging centers, outcome questionnaires, a clearinghouse and a patient portal all need connecting, which off-the-shelf tools may limit.
Whichever route a clinic takes, ask the vendor or the build team to demonstrate the two-of-four check, the level-to-diagnosis link and the AT decision on a real visit, not on a slide.
How Agnotic can help
Agnotic Technologies builds chiropractic record systems for clinic groups and health software companies. We design the exam forms around PART findings and spinal levels, build the rules that check each note before signing, and generate claims whose codes and modifiers follow from what the clinician recorded.
Agnotic also connects the record to the clinic's clearinghouse, imaging providers and patient intake tools, so that documentation, scheduling and billing work from one set of data.
