Acupuncture Medical Billing Services
Acupuncture billing turns on two things settled before a needle goes in: whether the visit is covered, and whether the time is documented the way time-based codes require. The codes run in 15-minute increments of one-on-one personal contact and fork on whether electrical stimulation was applied, and only one initial code is billable per session. Coverage is narrower still. Medicare covers acupuncture only for chronic low back pain, and only within published limits — 12 visits in 90 days, 8 more only for a patient who is demonstrably improving, and no more than 20 treatments a year. Those limits are enforced by claim edits, not judgement: past 12 services in a year the claim needs a KX modifier or the contractor returns it unprocessable, and past 20 it is denied. Commercial plans vary so widely that treating before verifying benefits is how practices end up working for free.
We bill around those two axes. Before the first visit we verify the benefit, the visit cap and any authorization requirement, and give the front desk a covered-visit count and a per-visit patient amount. We code each session to documented one-on-one time and stimulation status, keep a Medicare visit counter per patient, add the KX exception where the documented conditions are met, and stop at 20. Non-covered visits go out on the patient-responsibility path with advance written notice on file rather than as a claim that will deny, and claims are followed to a posted payment, a worked denial or a patient statement.

How is acupuncture billed?
Acupuncture is billed on time-based CPT codes that fork on whether electrical stimulation was applied: one initial code per session, additional units in 15-minute increments of one-on-one personal contact, and units that have to match documented face-to-face time rather than the length of the appointment. Coverage is settled first. Medicare covers acupuncture only for chronic low back pain, and only within published limits: CMS MLN Matters article MM11755 states that “Up to 12 visits in 90 days are covered,” that CMS will “cover an additional 8 sessions for those patients demonstrating an improvement,” and that “No more than 20 acupuncture treatments may be administered annually.” Commercial coverage ranges from generous to none. We verify the benefit before the first visit, code each session to documented time and stimulation status, and keep the Medicare visit count on our side so the cap is managed rather than discovered on a remittance.
- 97810/97811 = acupuncture without e-stim; 97813/97814 = with e-stim
- Time-based: 15-minute increments of one-on-one personal contact
- Only one initial code (97810 or 97813) per session
- Medicare: chronic low back pain only — 12 visits/90 days, 8 more if improving, 20/year cap

Common Billing Friction in Acupuncture
Time-based coding in 15-minute increments
Acupuncture codes are timed: 97810 and 97813 cover the initial 15 minutes of one-on-one personal contact, and 97811 and 97814 each cover an additional 15 minutes. Units must match documented face-to-face time, and re-insertion of needles is required to report an additional timed unit. Billing units that documentation doesn't support is the fastest route to an acupuncture audit.
The electrical-stimulation split (97810/97811 vs 97813/97814)
The code set forks on whether electrical stimulation is applied. 97810/97811 report acupuncture without e-stim; 97813/97814 report acupuncture with e-stim. A session cannot report both an initial without-stim and an initial with-stim code — only one initial code is billable per session — so the distinction has to be documented and coded correctly the first time.
Medicare's chronic-low-back-pain-only coverage
Medicare covers acupuncture only for chronic low back pain — defined by CMS as pain lasting 12 weeks or longer, nonspecific, not associated with surgery and not associated with pregnancy — for dates of service on and after 21 January 2020. The allowance is 12 visits in 90 days, a further 8 sessions only where the patient is demonstrably improving, and 20 treatments a year at the outside, and CMS states treatment must be discontinued if the patient is not improving or is regressing. Acupuncture for any other diagnosis is not a Medicare benefit. Because CMS told its contractors to return claims past 12 services a year as unprocessable when the KX modifier is missing and to deny past 20, the visit counter and the KX exception are billing work with a deadline, not clinical paperwork. The same CMS article lists 20560 and 20561 alongside 97810–97814 as payable under that policy. (CMS MLN Matters MM11755, verified 17 September 2026.)
Commercial coverage variability and benefit verification
Commercial acupuncture coverage ranges from generous visit allowances to no benefit at all, with plan-specific visit caps, diagnosis requirements, and prior-authorization rules. Verifying benefits before the first needle — coverage, visit limits, copay, and any authorization requirement — is what separates a paid acupuncture practice from one absorbing non-covered visits.
Provider-type and supervision rules
Payers differ on which provider types they reimburse for acupuncture and under what supervision, and Medicare's coverage carries its own supervision conditions. Claims that don't match the payer's provider and supervision requirements deny regardless of correct coding.
Acupuncture-Specific Payer Issues We Watch For
Medicare
Issue: Covers acupuncture only for chronic low back pain, for dates of service on and after 21 January 2020, at 12 visits per 90 days, 8 more only where the patient is improving, and 20 per year maximum; all other acupuncture is non-covered.
Our approach: We track the visit count per patient, add the KX modifier past 12 services in the benefit year, stop at 20, and route non-covered acupuncture to patient responsibility with advance written notice rather than into a denial.
Commercial (varies by plan)
Issue: Coverage ranges from generous to none, with plan-specific visit caps, diagnosis rules, and prior-auth requirements.
Our approach: We verify benefits and any authorization requirement before the first visit, so the practice treats with a clear picture of what's payable.
All payers
Issue: Time-based units billed beyond documented one-on-one contact, or an initial code billed for both e-stim and non-e-stim in one session.
Our approach: We code units to documented time and the correct single initial code per session, keeping claims audit-defensible.
What We Handle
Time-based acupuncture coding (97810–97814)
We code each session to documented one-on-one time and the correct e-stim status — initial and additional units for 97810/97811 or 97813/97814 — so units are audit-defensible instead of assumed.
Benefit verification before treatment
Before the first needle we run the plan: active coverage, whether acupuncture is a benefit at all, the visit cap and how it resets, copay and coinsurance, any diagnosis restriction, and whether the plan wants prior authorization or a referral. It comes back to the front desk as a number of covered visits and a per-visit patient amount, and it is re-run at plan year, so the clinic books against a known benefit instead of discovering it on a remittance eight weeks later.
Medicare chronic-low-back-pain compliance
We keep a running Medicare visit count per patient, append the KX modifier once a patient passes 12 services in the benefit year, and stop at 20. Where the diagnosis sits outside the chronic-low-back-pain policy, or treatment continues after the patient has stopped improving, the visit goes out on the non-covered path with advance written notice already on file rather than as a Medicare claim that will deny — which is what makes that balance collectable from the patient instead of a write-off.
Denial management on coverage and units
We work acupuncture denials by the code on the remittance rather than by resubmitting and hoping. CMS publishes the exact pairs its contractors use on this policy — CARC 50 with RARC M64 when the required diagnosis is missing, CARC 4 with RARC N657 when the KX modifier is missing past 12 services, CARC 96 with RARC N640 past 20 — and each one has a different fix: correct and resubmit, add the modifier, or move the balance to the patient. Commercial visit-cap denials get the same treatment against that plan's own benefit language.
A/R follow-up and patient balances
Every claim is followed to a posted payment, a worked denial or a patient balance — nothing sits in limbo. Claims age weekly, unpaid ones get chased at the payer instead of waiting on a second remittance, and non-covered visits move onto a patient statement while the visit is recent enough for the patient to recognise it.

Key Acupuncture CPT Codes
| CPT Code | Description | Medicare Amount CY2026 national, non-facility |
|---|---|---|
| 97810 | Acupuncture, 1+ needles; without electrical stimulation, initial 15 min of personal one-on-one contact | — |
| 97811 | Acupuncture, 1+ needles; without electrical stimulation, each additional 15 min (with re-insertion) | — |
| 97813 | Acupuncture, 1+ needles; with electrical stimulation, initial 15 min of personal one-on-one contact | — |
| 97814 | Acupuncture, 1+ needles; with electrical stimulation, each additional 15 min (with re-insertion) | — |
Amounts are the Medicare national unadjusted non-facility amounts for CY2026, computed from the published CMS relative value file. They are not what a commercial payer pays, and your locality adjustment moves them. A dash means Medicare publishes no amount for that code — because it is non-covered, bundled, or priced outside the fee schedule.
Why General Billing Teams Miss Acupuncture Issues
General billing staff handle dozens of specialties and rarely develop the depth needed for acupuncture coding nuances. Here is what gets missed.
Modifier and bundling errors
Specialty-specific modifier rules and CCI edits are frequently overlooked by teams that do not work exclusively in acupuncture.
Under-coding high-complexity visits
Acupuncture encounters often qualify for higher-level E/M codes, but generalist billers default to mid-level codes to avoid audit risk.
Missed payer-specific rules
Each payer has unique coverage and documentation requirements for acupuncture procedures that general teams rarely memorize.
Slow denial turnaround
Without specialty knowledge, appeal letters lack the clinical specificity needed to overturn acupuncture denials quickly.

Acupuncture Billing Terms
- Electrical stimulation (e-stim)
- Application of a small electrical current to acupuncture needles. It determines the code set: 97813/97814 with e-stim versus 97810/97811 without — the two are billed as separate initial codes and cannot both be initial in one session.
- Time-based coding
- Billing by documented units of time — here, 15-minute increments of one-on-one personal contact. Additional units require both documented time and needle re-insertion, and must match the record.
- KX modifier (Medicare acupuncture)
- The modifier that tells a Medicare contractor the documented coverage conditions are met on an acupuncture claim past the first 12 services in a benefit year. CMS instructed contractors to return such claims as unprocessable when it is missing, so it is a billing-side exception the clinic has to be tracked into, not a clinical one.

Request ReviewWhat CPT codes are used for acupuncture?
Acupuncture uses four time-based CPT codes split by electrical stimulation: 97810 (initial 15 minutes without e-stim), 97811 (each additional 15 minutes without e-stim), 97813 (initial 15 minutes with e-stim), and 97814 (each additional 15 minutes with e-stim). Only one initial code (97810 or 97813) is billed per session, and additional units require documented one-on-one time and needle re-insertion.
Does Medicare cover acupuncture?
Only for chronic low back pain, and only within limits. CMS MLN Matters MM11755 states that Medicare covers acupuncture for chronic low back pain “effective for claims with DOS on and after January 21, 2020,” that “Up to 12 visits in 90 days are covered,” that CMS will “cover an additional 8 sessions for those patients demonstrating an improvement,” and that “No more than 20 acupuncture treatments may be administered annually.” It defines the covered condition as pain lasting 12 weeks or longer, nonspecific, not associated with surgery and not associated with pregnancy, and states that “Treatment must be discontinued if the patient is not improving or is regressing.” Past 12 services in a year the claim needs a KX modifier or the contractor returns it unprocessable. Acupuncture for any other condition is not a Medicare benefit and belongs on the patient-responsibility path, not on a Medicare claim.
Why do acupuncture claims get denied?
The most common reasons are coverage and units: billing a payer that doesn't cover acupuncture or a diagnosis outside its policy, exceeding plan visit limits, billing units beyond documented one-on-one time, or reporting both an e-stim and non-e-stim initial code in one session. Verifying benefits first and coding to documented time prevents most of them.
What is the difference between 97810 and 97813?
97810 reports the initial 15 minutes of acupuncture without electrical stimulation; 97813 reports the initial 15 minutes with electrical stimulation. They are mutually exclusive as initial codes for a session — you bill one or the other based on whether e-stim was applied, not both.
What does an acupuncture billing service actually do, and what stays with the clinic?
We take the revenue cycle; the clinic keeps the chart. Ours: verifying the benefit before the first visit and again at plan year, coding each session to documented one-on-one time and e-stim status, submitting and scrubbing claims, running the Medicare visit counter and the KX exception, posting payments, working denials to a cause rather than a resubmission, chasing aged claims, and statementing patients for non-covered visits. Yours: the treatment, the note and the decision to treat. We do not write your documentation — but we tell you, per denial, which line of it the payer could not find, because on time-based codes the note is the claim.
Is this worth it for a one- or two-practitioner clinic?
It turns on payer mix more than on size. A cash-only clinic does not need a biller. A clinic billing insurance does, because the work that protects acupuncture revenue — benefit checks, visit counters, KX tracking, denial follow-up — is per-patient and does not get cheaper at low volume; it just gets skipped. On price: MedPrecision charges 7.0% of monthly collections for solo practices and 6.0% for groups of 2–15 providers, with no setup fee, no per-claim charge and no software fee, billed on collections received rather than charges submitted. The solo tier carries a minimum monthly fee, set in your quote and service agreement rather than published, so a very low-volume month bills at the minimum instead of the percentage. For a small clinic that minimum, not the headline rate, is the number worth comparing — ask any billing company for it in writing, ours included.
