SPEECH + AUDIOLOGY BILLING · CY2026

Speech and Audiology in 2026: A Layered Look at Thresholds, Direct Access, and Telehealth

If you run a combined speech and audiology practice, three different CMS rules are hitting the same claim file. The trick is not one policy for everything. It is billing each service line under its own correct rule.

⚡

Short answer: speech-language pathology rides the KX therapy threshold (PT and SLP share one combined cap), audiology now bills a slice of diagnostics under direct access with the AB modifier, and SLP telehealth stays payable while its statutory extension holds. Stack them, do not blend them.

// THE THREE LAYERS

One practice, three rulebooks, stacked

Each card below is a self-contained billing layer. A dual-discipline practice runs all three at once, and a claim only clears when it matches the layer it actually belongs to.

LAYER 01
KX THRESHOLD

Speech-Language Pathology

SLP evaluation, treatment, swallowing, cognition

Medicare has no hard dollar cap on therapy, but once a beneficiary's incurred SLP expense crosses the annual threshold you must append the KX modifier to attest medical necessity. Miss it and the line denies. The catch operators forget: PT and SLP draw from one shared threshold, so a patient getting both burns the cap twice as fast.

KX modifier PT + SLP combined CY2026 MPFS MR at $3,000

Bill it this way

  • Track PT and SLP dollars against one running total per patient
  • Append KX only when documentation supports medical necessity above the cap
  • Expect targeted medical review once a patient passes $3,000

Where it breaks

  • Treating the SLP cap as separate from PT
  • Auto-KX on every line "to be safe" (audit exposure)
  • Using the 2025 figure after the CY2026 amount posts
LAYER 02
AB DIRECT ACCESS

Audiology Diagnostics

Non-acute diagnostic audiology, no physician order

This is the newer layer most billing teams under-use. Under the direct-access provision CMS finalized in the CY2023 MPFS and carried forward, an audiologist may furnish selected non-acute diagnostic services without a physician or NPP order by appending the AB modifier. It is deliberately narrow: non-acute hearing and balance conditions, and once every 12 months per beneficiary for that direct-access pathway.

AB modifier no order required non-acute only 1 per 12 months

Bill it this way

  • Append AB on qualifying non-acute diagnostic codes furnished without an order
  • Document that the presentation is non-acute and within scope
  • Track the 12-month clock per patient so the next direct visit still needs an order

Where it breaks

  • Using AB on acute or treatment-related visits
  • Stacking AB with a same-year direct-access encounter
  • Applying it to codes outside the finalized direct-access list
LAYER 03
TELEHEALTH

SLP Telehealth Eligibility

Remote speech services, place-of-service + modifier driven

SLPs remain eligible Medicare telehealth practitioners, and qualifying speech codes stay on the Medicare telehealth list in the CY2026 MPFS. The live variable is statutory: the broad non-behavioral telehealth flexibilities run on short Congressional extensions, so eligibility is real but date-sensitive. Bill it right and verify the current extension window before every quarter.

SLP eligible practitioner telehealth code list POS 10 / 02 extension-dependent

Bill it this way

  • Confirm the code is on the current Medicare telehealth list
  • Use the correct place-of-service (home vs. facility) and any required modifier
  • Re-check the flexibility expiration date each billing cycle

Where it breaks

  • Assuming permanent coverage and skipping the expiration check
  • Wrong POS on home-based sessions
  • Billing a code that never made the telehealth list

One combined claim file, three rule paths

The same front desk, the same patient, the same day. Where the encounter routes decides which rule governs the line. This is why a single blanket billing policy leaks money.

COMBINED
PRACTICE
SLP + Audiology under one TIN
SLP visit → check shared PT/SLP running total → append KX above threshold
Non-acute audiology diagnostic, no order → append AB, log 12-mo clock
Remote speech session → verify telehealth list + POS → bill within active extension
// THE NUMBERS THAT GATE PAYMENT

The speech-side dollar ladder

Two thresholds move the SLP claim. One triggers a modifier, the other triggers a reviewer. Track both per patient, not per visit.

KX modifier threshold · PT + SLP combined

$2,410*

*CY2025 published amount, indexed by the Medicare Economic Index. Use the figure confirmed in the CY2026 Medicare Physician Fee Schedule final rule and MLN once posted. Above this line, KX is required to keep paying.

Targeted medical review threshold

$3,000

Held at $3,000 through CY2027 by statute (Bipartisan Budget Act of 2018). Crossing it does not stop payment, but it flags the patient for potential targeted review, so documentation has to be airtight.

ASP-RCM Solutions builds the KX shared-cap tracking, AB direct-access logic, and telehealth eligibility checks straight into your claim edits, so a combined speech and audiology practice stops losing lines to the wrong rule. Fewer threshold denials, cleaner audit posture, faster cash.
