SNF Medicare Part B Billing
Part B billing for SNF therapy and physician services. CMS-1500 and 837P claims for PT, OT, SLP services after the 100-day Part A benefit, plus excluded ancillary services under 42 CFR 411.15. KX modifier tracking, therapy threshold monitoring, manual medical review response. We work inside PointClickCare and MatrixCare alongside your therapy directors.
0:55
0:48KX modifiers missed. Thresholds blown. Part B revenue stuck.
When the Part A 100-day benefit ends or the resident never qualified for Part A, SNF therapy and many ancillary services shift to Part B billing on CMS-1500 or 837P claims. Section 50202 of the Bipartisan Budget Act of 2018 ended the hard therapy cap but kept the thresholds that trigger the KX modifier and manual medical review. Most SNF business offices treat Part B as an afterthought, and the rejections stack up.
KX modifier not appended
Once outpatient therapy charges cross the annual threshold ($2,330 PT plus SLP combined, $2,330 OT for 2026), the KX modifier must be appended to attest medical necessity. Miss it and the MAC will reject the claim. The KX rule under Section 50202 BBA is unforgiving.
Manual medical review surprises
Above the targeted medical review threshold ($3,000 per discipline for 2026), claims trigger manual medical review by the MAC or a Targeted Probe and Educate review. Without proactive documentation packaging, these claims sit in review for 60 plus days.
Consolidated billing exclusions missed
42 CFR 411.15 lists ancillary services SNFs cannot include in the Part A per-diem (certain chemotherapy, radiology, ESRD). When the resident is on Part A, those still must be billed on Part B but by the outside provider. When the resident is not on Part A, the SNF bills them on CMS-1500. Most billers confuse the two paths.

What is SNF Medicare Part B billing ?
SNF Medicare Part B billing is the end-to-end process of billing professional and ancillary services for SNF residents on Part B, either because the Part A 100-day benefit ended, the resident never met Part A criteria, or the service falls inside the 42 CFR 411.15 consolidated billing exclusion list. Claims go out on CMS-1500 (paper) or 837P (electronic professional) to the Medicare Administrative Contractor, not on UB-04.
What your Part B billing team actually handles, day to day
Eight production queues that map directly to the SNF Part B lifecycle. From therapy charge entry to manual medical review response, your billing pod covers every step.
CMS-1500 and 837P submission
Builds professional claims with HCPCS and CPT codes for PT (97110, 97112), OT (97530), SLP (92507). Submits through clearinghouse with edits resolved.
Therapy threshold tracking
Runs daily totals against the annual therapy threshold ($2,330 PT plus SLP, $2,330 OT for 2026). Flags residents within 200 dollars of the threshold for the therapy director.
KX modifier application
Appends the KX modifier when the threshold is crossed under Section 50202 BBA. Audits claim line items to confirm KX was attached before submission.
Manual medical review response
Packages documentation when claims cross the targeted review threshold ($3,000 per discipline). Drafts the medical necessity narrative and attaches POC and progress notes.
Consolidated billing logic
Applies the 42 CFR 411.15 exclusion list to decide which services bill on CMS-1500 versus which excluded ancillaries the outside provider bills directly during a Part A stay.
MAC rejections and rebills
Reads 277CA acknowledgments. Resolves CARC and RARC codes, modifier mismatches, and POS errors. Re-bills within timely filing.
Five-level Part B appeals
Drafts redetermination requests with the MAC, reconsideration requests to the QIC, ALJ hearings, Medicare Appeals Council reviews, and Federal District Court referrals when justified.
835 remit reconciliation
Posts ERA against the Part B fee schedule. Splits MSP and secondary balances. Flags underpayments against the published RVU and conversion factor.
Part B-tested billers, not generic medical coders
Most outsourcing companies will assign a general medical coder to your SNF Part B queue and call them a "therapy biller." We do not. Every Staffingly biller on a Part B account passes a pre-placement assessment on Section 50202 BBA thresholds, KX modifier rules, the 42 CFR 411.15 consolidated billing exclusion list, and at least one major platform from PointClickCare, MatrixCare, or Net Health.
Part B-tested pre-placement
Every biller passes a written assessment on CMS-1500 box-by-box, therapy CPT and HCPCS codes, KX modifier rules, the therapy threshold math, and the 42 CFR 411.15 exclusion list before placement on a live SNF account.
Stacked compliance posture
HIPAA + SOC 2 Type II + ISO 27001 + HITRUST. Plus alignment with 42 CFR 411.15 Part B rules and 45 CFR 164.514 de-identification. Ask your current vendor for proof of all four.

Industry standard offers no trial. We give you 14 days of live Part B claim work at the same rate. Cancel before day 14, owe nothing. No annual contracts after.

Frequently asked questions
What are the five PDPM case-mix components, and how do they affect the per-diem?
PDPM uses five separate case-mix components under 42 CFR 483: PT, OT, SLP, Nursing, and NTA. Each has its own case-mix index and base rate. The HIPPS code captures all five. PT and OT use Section GG functional scores. SLP uses cognitive status, swallowing, and mechanical altered diet. Nursing uses 25 categories tied to ADL and special care. NTA uses a 50-condition comorbidity list. Together they drive the Part A per-diem.
When should an IPA be triggered?
IPA is optional under PDPM but recommended when a clinical change shifts a case-mix component: nursing acuity change, therapy regimen modification, NTA comorbidity onset, or significant functional decline. The IPA ARD must be set within 14 days of the change.
How is the Interim Payment Assessment timed and submitted?
The IPA ARD can be set on any day during the Part A stay after the 5-day. Once submitted to iQIES, the new HIPPS applies prospectively from the ARD forward. Original 5-day HIPPS still applies before the IPA ARD. UB-04 line items are split by date range.
How is PDPM different from RUG-IV?
RUG-IV was minutes-driven. PDPM shifted to clinical characteristics: ICD-10 diagnoses, Section GG functional scores, NTA comorbidities. PDPM introduced variable per-diem (PT and OT step-down after day 20, NTA 3x for days 1 to 3) and made IPA optional. Took effect October 1, 2019 under 42 CFR 483.
What is the difference between MS-DRG and HIPPS coding?
MS-DRG is the inpatient hospital Part A payment classification under 42 CFR 412. HIPPS is the SNF Part A payment code under 42 CFR 483. The 5-day MDS generates the HIPPS code that drives SNF per-diem for the post-acute stay.
How is PHI and HIPAA handled for remote PDPM billing?
Full HIPAA-aware workflow with signed BAA, role-based EMR access, and audit logging under 45 CFR 164.514 de-identification rules where applicable. Billers work from biometric-secured facilities under HIPAA, SOC 2 Type II, HITRUST, and ISO 27001 aligned controls.
How does pricing work for PDPM billers across multiple SNFs?
Per Part B biller FTE, per week. No setup fees. $399 Standard, $349 Volume (3 or more), $299 Enterprise (10 or more). Add or remove billers by the week. No annual contracts. Multi-state SNF groups can pool billers across facilities.
What is included in the 2-Week Risk-Free Pilot for PDPM billing?
Two weeks of live PDPM billing work in parallel with your business office. Full reporting on clean-claim rate, HIPPS validation, IPA recommendations, and NTA captures. No setup fee. No penalty if you cancel before day 14.
