Support Taxonomy Primer: Navigating NDIS Categories and Coding
4/21/2026
1. Decoding the NDIS Support Item Number
The NDIS identification system uses a 15-digit alphanumeric structure to track every service delivered. For the educator and the student alike, this code is not merely an administrative label; it is the fundamental mechanism for ensuring financial accountability and alignment with participant goals.
The Anatomy of a Code
Using the specific example 01_013_0107_1_1 (Assistance with Self-Care Activities – Standard – Saturday), we can dissect the code into its five constituent parts:
Code Segment | Segment Name | Definition |
01 | Support Category | Identifies the specific funding pool (1–15) within the participant's budget. |
013 | Sequence Number | A unique internal identifier for the specific service type. |
0107 | Registration Group | Identifies the specialized skill set required (e.g., Daily Personal Activities). |
1 | Outcome Domain | Corresponds to the specific life area (1-8) of the Outcomes Framework (e.g., 1 = Daily Living). |
1 | Support Purpose | Identifies the broad budget purpose (1 = Core, 2 = Capital, 3 = Capacity Building). |
Professional Practice Tip: To verify that a provider is claiming against the correct category, you must cross-reference the 15-digit Support Item Number on the invoice with the NDIS Support Catalogue and the specific line items approved in your NDIS Plan. If these codes do not match exactly, the claim may be invalid or incorrectly deducted from the wrong budget pool.
Understanding these numerical sequences is the first step toward categorizing services under the three overarching Support Purposes.
2. The Three Core Support Purposes
NDIS funding is partitioned into three primary purposes. While a fourth category, "Recurring," exists for specific transport payments, it is treated separately from the primary budget pools because it represents regular, non-flexible payments.
- CORE: These supports facilitate activities of daily living and are the most utilized portion of a plan.
- Benefit: Provides immediate assistance for day-to-day needs like self-care, consumables, or social participation.
- Flexibility: These budgets are generally flexible, allowing participants to shift funds between categories (e.g., from Transport to Consumables) to meet changing needs.
- CAPITAL: This represents an investment in high-cost infrastructure and assets.
- Benefit: Covers one-off costs for assistive technology, home modifications, or Specialist Disability Accommodation (SDA).
- Flexibility: This budget is highly restricted; funds are "stated" and can only be used for the specific equipment or modifications identified in the plan.
- CAPACITY BUILDING: These supports are oriented toward long-term independence.
- Benefit: Funds professional services like therapy, training, and support coordination to help participants build skills to achieve their goals.
- Flexibility: These funds are restricted to specific categories (e.g., you cannot use "Improved Learning" funds for "Improved Health and Wellbeing") and cannot be moved to Core or Capital budgets.
These three purposes serve as the functional vehicles for achieving the specific results outlined in the NDIS Outcomes Framework.
3. Mapping Support Categories to Outcome Domains
The NDIS Outcomes Framework measures the effectiveness of the scheme across eight life domains. In the shift from the Legacy (CRM) system to the PACE system, the naming conventions have evolved, but the alignment remains critical for compliance.
Support Purpose | Outcome Domain | Support Category (Legacy CRM) | Support Category (PACE) |
CORE | Daily Living | 01 Assistance with Daily Life | 01 Assistance with Daily Life; 16 Home and Living |
CORE | Daily Living | 02 Transport | 02 Transport |
CORE | Daily Living | 03 Consumables | 03 Consumables |
CORE | Social/Community/Work | 04 Assist. Social & Community Participation | 04 Assist. Social & Community Participation |
CAPITAL | Daily Living | 05 Assistive Technology | 05 Assistive Technology; 19 AT Maintenance |
CAPITAL | Home | 06 Home Mods and SDA | 06 Home Modifications; 17 SDA |
RECURRING | Daily Living | N/A | 18 Recurring Transport |
CAPACITY BUILDING | Choice and Control | 07 Support Coordination | 07 Support Coordination & Recovery Coach |
CAPACITY BUILDING | Home | 08 Improved Living Arrangements | 08 Improved Living Arrangements |
CAPACITY BUILDING | Social/Community | 09 Increased Social & Community Participation | 09 Increased Social & Community Participation |
CAPACITY BUILDING | Work | 10 Finding and Keeping a Job | 10 Finding and Keeping a Job |
CAPACITY BUILDING | Relationships | 11 Improved Relationships | 11 Relationships; 20 Behaviour Support |
CAPACITY BUILDING | Health & Wellbeing | 12 Improved Health and Wellbeing | 12 Health and Wellbeing |
CAPACITY BUILDING | Lifelong Learning | 13 Improved Learning | 13 Lifelong Learning |
CAPACITY BUILDING | Choice and Control | 14 Improved Life Choices | 14 Choice and Control |
CAPACITY BUILDING | Daily Living | 15 Improved Daily Living Skills | 15 Improved Daily Living Skills |
Real-Life Support Examples
- Daily Living: Assistance with Self Care (Domain 1).
- Improved Learning: Specialised Driver Training (Domain 4).
- Health and Wellbeing: Dietetics or Exercise Physiology (Domain 3).
- Relationships: Specialist Behavioural Intervention Support (Domain 7).
While the taxonomy defines what supports are, the NDIS also enforces strict regulations on how they are claimed.
4. Essential Claiming Rules for the Learner
Travel Costs
Provider travel is subject to the Modified Monash Model (MMM), which determines the remoteness of the participant's location.
Region Type | MMM Classification | Travel Time Limit (One-Way) | Non-Labour Rate (Vehicle) |
Major Cities / Regional Centres | MMM 1–3 | Up to 30 Minutes | Non-Modified: $0.99/km <br> Modified/Bus: $2.76/km |
Regional Areas | MMM 4–5 | Up to 60 Minutes | Non-Modified: $0.99/km <br> Modified/Bus: $2.76/km |
Remote / Very Remote | MMM 6–7 | No hard limit | Negotiable |
The Therapy Rule: For therapy providers, travel time is billed at 50% of the standard hourly rate for that support item.
Cancellations
A "Short Notice Cancellation" allows providers to claim 100% of the fee if the participant fails to provide sufficient notice.
- Non-DSW Supports (Therapists, Coordinators, Nurses): Requires 2 clear business days' notice.
- DSW Supports (Disability Support Workers): Requires 7 days' notice.
Non-Direct Services
"Non-Face-to-Face" supports (e.g., report writing) are billable only if specified in the service agreement. However, providers are strictly forbidden from billing for the following administrative tasks:
- Making payment claims or processing invoices.
- Pre-engagement visits or interviewing new staff.
- Developing or agreeing on Service Agreements.
- Making or amending service bookings or participant system details.
- Completing a quoting tool.
The application of these rules often depends on the specific Registration Group the provider belongs to.
5. Understanding Registration Groups and Provider Roles
Registration Groups are regulatory categories that ensure providers possess the mandatory qualifications and insurance to deliver specific high-risk or professional supports.
Key Registration Groups
- 0107 (Daily Personal Activities): Standard one-on-one care for daily living.
- 0128 (Therapeutic Supports): Allied health services (OT, Physio, Speech).
- 0111 (Home Modifications): Structural changes to a dwelling.
- 0131 (Specialised Disability Accommodation): Provision of specialized housing.
Professional and Therapy Roles
The NDIS defines strict qualifications for various roles to maintain clinical safety.
Role | Requirement / Qualification |
Physiotherapist | Must hold current AHPRA registration. |
Psychologist | Must hold AHPRA registration (includes supervised provisionally registered psychologists). |
Nurse Practitioner | Advanced practice nurse endorsed by the Nursing and Midwifery Board of Australia. |
Therapy Assistant (L1) | Must work under direct supervision of a therapist at all times. |
Therapy Assistant (L2) | May work under indirect supervision if the therapist deems them competent for independent delivery. |
Service Agreement Checklist
Before signing, ask:
- Does your organization hold the specific Registration Group (e.g., 0128 or 0110) for this support?
- Are your hourly rates exactly at or below the 2025-26 NDIS Price Limits for my MMM zone?
- Does this agreement clearly define the notice period for Short Notice Cancellations based on whether the worker is a DSW or Non-DSW?
6. Regional and Remote Pricing Adjustments
The NDIS acknowledges the increased cost of service delivery in isolated areas through price loadings.
- Remote Areas (MMM6): 40% loading applied to price limits.
- Very Remote Areas (MMM7): 50% loading applied to price limits.
The "Location of Participant" Rule
A critical regulatory principle is that the price limit is determined by the location of the participant at the time of delivery, not the location of the provider's office. If a city-based therapist (MMM1) travels to a remote town (MMM6) to see a participant, they claim the 40% Remote loading. Conversely, if a remote participant travels to a metropolitan clinic, the standard MMM1 price limit applies.
