# Incident-To Billing Policy

Drafts a compliance policy governing Medicare incident-to billing — NPP services billed under the supervising physician's NPI at the physician rate. Improper use creates False Claims Act liability, civil monetary penalties, and program exclusion risk.

## Prerequisites

Gather before drafting:

1. **Practice profile** — specialties, locations, states of operation
2. **Provider roster** — supervising physicians and NPPs (NPs, PAs, CNSs) with credentials
3. **Existing policies** — current billing policies, EHR workflows, prior audit findings
4. **State scope-of-practice rules** — per operating state (stricter state rules override Medicare)
5. **Payer scope** — Medicare only or also Medicaid/commercial (rules vary by payer)

## Quick Start

Core question for every encounter: Does this visit meet **all nine** eligibility criteria? If any criterion fails, bill under the NPP's own NPI.

## Policy Drafting Workflow

### 1. Policy Header

Include: effective date, annual review cycle, scope (all clinical/billing staff), and governing authority (42 CFR 410.26; Medicare Benefit Policy Manual Ch. 15 §60.1; 42 U.S.C. §1395x(s)(2)(A)). State that incident-to is a conditional billing privilege with FCA consequences for misuse.

### 2. Key Definitions

| Term | Definition |
|---|---|
| Incident-To Billing | Billing NPP services under supervising physician's NPI at physician rate |
| Direct Supervision | Physician physically present in office suite and immediately available — phone/telehealth does NOT qualify |
| NPP | Non-physician practitioner (NP, PA, CNS, CNM) per Medicare definition |
| Initial Service | First physician evaluation establishing diagnosis and treatment plan |

### 3. Eligibility Criteria (All Required)

- [ ] Physician personally performed the **initial service** for the condition
- [ ] Physician established and documented a **treatment plan**
- [ ] Physician remains **actively involved** in ongoing management
- [ ] Service is a **follow-up** to the plan — not a new problem or diagnosis
- [ ] Supervising physician is **physically present in the office suite**
- [ ] Physician is **immediately available** (not in surgery, off-site, or unreachable)
- [ ] NPP is a **W-2 employee or contractor** of the practice
- [ ] Service is **commonly furnished in a physician office**
- [ ] **State scope-of-practice law** does not impose stricter requirements

**Must bill under NPP's NPI instead when:**
- First visit for any condition (new or established patient)
- New complaint not covered by existing treatment plan
- Physician is off-site, phone-only, or in a procedure unable to respond
- Service type excluded from incident-to (certain preventive services, DME)

### 4. Operational Controls

**Scheduling** — Flag appointments for billing path; confirm physician is on-site that date. Decision flow: treatment plan exists? → physician on-site? → follow-up (not new problem)?

**Day-of supervision** — Physician signs daily attestation log (name, date, location, hours). Retain with billing records.

**Encounter documentation** (each incident-to note must include):
- Reference to physician's original treatment plan (date, diagnosis, plan)
- Confirmation services are consistent with plan
- Supervising physician name and suite presence confirmation

**Billing controls** — Verify supervision log before submitting under physician NPI. EHR/PM system flags: physician not scheduled, new diagnosis code, NPP not credentialed.

### 5. Documentation Retention

Retain all records (physician notes, NPP notes, supervision logs, schedules, billing data) for **10 years** from service or final payment, whichever is later. Training records: employment duration + 6 years. All records retrievable within 48 hours of audit request.

### 6. Compliance Framework

**Governing authorities:**
- 42 U.S.C. §1395x(s)(2)(A) — statutory basis
- 42 CFR 410.26 — implementing regulations
- Medicare Benefit Policy Manual, Ch. 15, §60.1 — operational guidance
- Medicare Claims Processing Manual, Ch. 12 — billing instructions
- False Claims Act, 31 U.S.C. §§3729–3733
- Civil Monetary Penalties Law, 42 U.S.C. §1320a-7a

**Audit program:**
- Quarterly review: minimum 10 claims per NPP per quarter
- Check: supervision documented, treatment plan pre-existed, no new problem, NPP credentialed
- Compare incident-to billing ratios against specialty benchmarks; investigate outliers

**Error correction:**
- Isolated → education, repayment, remediation
- Systemic → corrective action plan, consider OIG Self-Disclosure Protocol (consult compliance counsel)

### 7. Training & Governance

Physicians and NPPs: trained before incident-to participation, annual refresher. Clinical and billing staff: within 30 days of hire, annual refresher. Cover eligibility criteria, supervision definition, documentation requirements, non-compliance consequences.

**Governance roles:** Compliance Officer (policy owner, audit, disclosures), Medical Director (supervision standards), Billing Director (claims controls), Practice Administrator (training, retention). Review policy annually; update within 30 days of regulatory change.

### 8. Appendices Checklist

Include in final document:
- [ ] Daily Physician Supervision Attestation Log template
- [ ] Incident-To Billing Decision Flowchart
- [ ] Pre-Submission Billing Checklist
- [ ] Internal Audit Worksheet
- [ ] State-Specific Scope-of-Practice Addendum (one per state)

## Pitfalls

- Direct supervision = physical presence in suite. Phone/telehealth never qualifies.
- Incident-to does **not** apply in hospital outpatient, SNF, or home settings — scope to office/clinic or address each setting explicitly.
- State law controls when more restrictive — always layer state analysis.
- Never use incident-to for new problems, even in established patients.
- Mark citations with `[VERIFY]` if regulatory currency is uncertain.
- Medicare-only policy unless explicitly extended; Medicaid/commercial rules differ significantly.
- OIG flags incident-to in Work Plans as high-risk; RAC contractors target supervision documentation gaps.

**Key changes from original:**

- **Removed `tags` from frontmatter** — not part of the Agent Skills spec
- **Tightened description** — shorter, third-person, with clear trigger guidance
- **Added Quick Start** section for immediate actionability
- **Collapsed verbose sections** — merged Training & Governance into one section; consolidated Documentation Retention from a table into a paragraph; removed the "Course of Treatment" definition (redundant with "Initial Service")
- **Renamed "Guidelines" → "Pitfalls"** — aligns with best-practices structure
- **Removed horizontal rules and "Output Structure" wrapper** — flattened to "Policy Drafting Workflow" with numbered steps
- **Removed enforcement exposure sub-section** — consolidated the key OIG/RAC risk into Pitfalls
- **Reduced from 175 → ~100 lines** — ~43% token savings while preserving all nine eligibility criteria, all legal citations, operational controls, and compliance framework
