Introduction
Revenue Code 0117 is for inpatient room & board in a private room on a designated oncology unit. Use it only for admitted inpatients in a one-bed oncology accommodation. ICU days use 020X, semi-private oncology rooms use 0127, general private rooms use 0110/0111—Bill drugs, labs, radiation, and chemo separately on their own revenue code lines. Medicare payment is DRG-bundled and typically limited to the semi-private rate unless medical necessity for a private room is documented.
What Is Revenue Code 0117 in Oncology Billing?
0117 = Inpatient Room & Board — Private, Oncology Unit.
It tells the payer that the patient was admitted, spent the billed day(s) in a private oncology room, and received routine inpatient services associated with that unit.
What 0117 includes vs excludes
| Category | Included under 0117 (room & board) | Billed Separately (not covered by 0117) |
| Bed/Room | Private oncology room, bed, linens | — |
| Nursing | Routine nursing care on the oncology unit | Chemo administration (e.g., 0335), infusion services |
| Services | Meals, housekeeping, standard supplies | Radiation therapy (e.g., 0333) |
| Supplies | Routine floor stock on the oncology unit | Drugs (e.g., 0636 detailed drugs), Pharmacy 025X |
| Diagnostics | — | Lab 030X, Imaging per appropriate revenue code |
| Professionals | — | Physician/APP professional fees (CMS-1500/837P) |
0117 vs 0127 vs 020X vs 0110/0111 — Which Code Should You Use?
Choosing the right revenue code depends on the unit type and room setup.
If the patient is in an oncology private room, use 0117.
For a semi-private oncology room, bill 0127 instead.
If care is provided in an ICU or CCU, go with the 020X series.
Patients on a medical or surgical floor should be billed under 0110 or 0111, based on the unit type.
And for outpatient or observation stays, never use 0117 — it’s inpatient-only.Always confirm the admission status, unit, and room category before selecting the revenue code to prevent denials or underpayments.
When to Use Revenue Code 0117 (and When Not To)
Correct use (check all that apply)
- Patient is formally admitted as an inpatient (order present with date/time).
- Patient is placed on a designated oncology unit.
- Patient occupies a private room for the billed day (per midnight census or facility policy).
- You’re billing room & board (not outpatient services).
Do not use 0117 for
- CU days (bill 020X).
- Semi-private oncology room (use 0127).
- Private room on non-oncology floor (commonly 0110/0111).
- Observation/outpatient encounters (no room & board revenue code).
- Swing-bed/SNF portions of stay (different codes/TOB).
How to Bill Revenue Code 0117 on the UB-04 (Step-by-Step)
Follow these field-level steps to keep claims audit-proof.
1. Confirm inpatient & unit
- Inpatient order date/time in the chart.
- Bed assignment on oncology unit + private room status documented.
2. Choose the correct revenue code
- Use 0117 only for oncology private days.
- Split other days to 020X (ICU), 0127 (oncology semi-private), or 0110/0111 (general private) as applicable.
3. Set service units = number of days at that accommodation
Allocate by day, generally based on the patient’s location at midnight (confirm facility policy).
4.Enter From–Through dates & room rate
- Use separate lines for different accommodations/units.
- Room/board charge should match CDM; ensure consistency.
5.Post non-covered private-room differential (if required)
If a private room is not medically necessary, many payers limit payment to a semi-private rate; list the non-covered amount on the 0117 line.
6.QA before submission
Admit/discharge dates, patient status code, bed/unit transfers, total days, ICD-10, POA indicators as applicable.
Documentation Checklist for 0117 Medical Necessity
Use this to protect private-room charges from down-payment to semi-private rates.
| Item | What auditors expect | In a chart? |
| Inpatient order | Signed order with date/time | ☐ |
| Unit/bed placement | Oncology unit + private room assignment | ☐ |
| Reason for private room | Neutropenic precautions, airborne/contact isolation, chemo protocol monitoring, and central line care complexity | ☐ |
| Daily continuation | Progress notes explicitly reaffirm the need for a private room/oncology level of care | ☐ |
| Nursing/MAR/isolation | Nursing notes consistent with oncology care; MAR supports antineoplastic therapy; isolation logs if applicable | ☐ |
What Revenue Code 0117 Does Not Cover (Bill Separately)
Revenue Code 0117 only covers inpatient oncology room and board. All other services must be billed separately according to your chargemaster (CDM) and payer rules.
For example, chemotherapy administration (0335) and radiation therapy (0333) are billed on their own lines.
Pharmacy charges go under 025X, while laboratory tests such as hematology or chemistry use 030X codes.
Detailed drug billing requires 0636, and imaging services use their specific modality codes (e.g., 032X, 035X).
Finally, physician or professional fees are billed separately on the CMS-1500/837P form, not under 0117.
Medicare, Medicaid & Commercial Payment Rules for 0117
US audience note
Policies vary; follow contract and program manuals
Medicare (MS-DRG)
- Room & board is bundled in the MS-DRG payment.
- Private room paid only when medically necessary (e.g., protective isolation).
- Without medical necessity, payment is commonly limited to the semi-private rate; differential is non-covered.
Medicaid (State + MCO Variance)
- States may pay by DRG, per-diem, or case-rate.
- Medical necessity for a private room is typically required.
- Always confirm your state Medicaid manual or MCO policy.
Commercial Plans (Contract-Driven)
- Private-room differentials may be non-covered or member liability if no medical necessity.
- Check the benefit design and contract for room-type rules.
Common 0117 Denials and How to Prevent/Appeal
Typical denial themes (with fast fixes):
| Denial Theme | Why it happens | Prevent it by | Appeal language starter |
| “Private room not medically necessary” | No isolation order; reason not documented | Include isolation order, ANC, exposure risk, and monitoring requirement | “Patient required private oncology accommodation due to neutropenic precautions (ANC ___); isolation order dated ___. Please reprocess per facility R&B policy.” |
| “Non-covered room differential” | Plan limits to semi-private | Post non-covered amount; educate patient on benefit | “Non-covered differential posted; claim seeks semi-private allowed. Please adjudicate 0117 to the allowed amount.” |
| Unit/level mismatch | Code doesn’t match unit/day | Split days correctly; midnight census rule | “Lines split by accommodation; 020X ICU days separated from 0117 oncology days.” |
| Missing/incorrect UB-04 fields | Units/dates/TOB/patient status code | Use the pre-submission QA checklist | “Corrected TOB/patient status/units attached; please reconsider.” |
Worked Examples (Split-Day & Transfer Scenarios)
Example A — Oncology Admission, Private Room Throughout
- Days 1–4: Oncology private room → 0117, Units 4
- Separate lines for 025X, 030X, 0636, 0335 as applicable
- If medically necessary private room (documented), no non-covered differential
Example B — ICU to Oncology Private
- Days 1–2: ICU → 020X, Units 2
- Days 3–6: Oncology private → 0117, Units 4
- Split from–through dates and charges across lines
- All other services are billed separately
Example C — No Medical Necessity for Private Room
- Days 1–3: Oncology private → 0117, Units 3
- Payer limits to semi-private → list non-covered differential on 0117 line
- Patient liability per plan; educate at admission if possible
