Understand HCPCS Code T1015 for all-inclusive FQHC & RHC visits, new 2024–2025 modifier requirements, billing rules, and compliance essentials.

Use Code

## **What is this code?** HCPCS code T1015 is designated as the clinic visit, all-inclusive code. It is used by providers, particularly Federally Qualified Health Centers (FQHCs) and Rural Health Clinics (RHCs), to bill for all-inclusive clinic visits or encounters that cover a set of core services provided during the visit. The "all-inclusive" nature means it encompasses multiple components of care typically bundled under this single code. ### **News and changes related to this code** There is significant news that changes one modifier 59 rule impacting claims submission for T1015, relevant for providers that may have a portion of their claims billed incorrectly (AAPC, 2024). For example, 40 percent of your claims could be impacted if you do not follow the new modifier rules correctly. Claims for T1015 must be billed in conjunction with the applicable CPT or HCPCS codes to identify specific services. Providers must use modifier 25 to indicate identifiable evaluation and management services rendered on the same day. Failure to do so or incorrect modifier use would be practice-ending for some, and providers who would ignore these changes face denials or audit risks . Medicaid programs have updated billing guidance requiring T1015 with specific modifiers (such as HI and SC) for core services billing from August 2024 onwards. This means claims were billed incorrectly before these updates took effect, and strict adherence to these changes is now necessary. Rate changes and billing compliance requirements are maintained by CMS, which falls under the prospective payment system (PPS), and T1015 is mandatory on FQHC and RHC claims for valid clinic visits starting mid-to-late 2024 and into 2025 (AAPC, n.d.). The rate at which the office receives payments is tied to this system, emphasizing the importance of using T1015 correctly for accurate payment (AAPC, 2024). Providers must also observe modifiers U1 or U2 in some states, along with T1015 for certain provider types, reflecting the evolving claims and billing landscape in 2024 and beyond.

## **Documentation requirements** Key documentation elements include: - - Thorough clinical notes that reflect the moderate level of medical decision-making involved, often addressing multiple diagnoses or prescription management. - Clear linkage of the services provided to the T1015 code, including any separately identifiable evaluation and management services billed with modifier 25, supported by medical documentation as required. - A description of the visit reasoning, findings, and interventions consistent with the comprehensive, all-inclusive visit concept. - Records demonstrating compliance with payer-specific billing guidelines and requirements for prior authorization or referrals, if applicable. - For Medicaid and Medicare claims, documentation must align with prospective payment system (PPS) rules and any state-specific requirements, such as the use of modifiers U1 or U2 on certain claims, as recently mandated by some states like Texas. - Avoid billing T1015 with excluded service codes such as dental, family planning, preventive medical exams, or vaccine administration unless specifically allowed by the payer. - Ensure all claims are supported by appropriate provider credentials (licensed professional counselors, marriage therapists, etc.) when billing behavioral health or counseling under T1015.

## **Billing requirements** Here are some billing guidelines for HCPCS code T1015 to follow: - Providers must bill T1015 once per day per member, along with qualifying CPT/HCPCS codes that specify services provided. - Claims billed without a qualifying evaluation and management code or with incorrect modifiers, including modifier 25 for separately identifiable services, will be denied. - The rate that the office receives is based on the prospective payment system (PPS) tied to the T1015 code. - Medicaid and commercial payers have specific billing guidelines; claims not following these will be denied. - Providers that would ignore these requirements risk denials and payment issues.

## **Other relevant codes** - **G0466–G0470**: Medicare FQHC visit codes (for new and established patients, effective 2014). - **99201–99215**: CPT office/outpatient E/M codes (informational only in FQHC/RHC claims). - **T1014** – Clinic visit, mental health services, per 15 minutes (sometimes paired with T1015 in Medicaid programs).
