Summary & Overview
CPT 3510F: Tuberculosis Screening and Interpretation for IBD Patients
CPT code 3510F indicates that a clinician documented tuberculosis (TB) screening and interpreted the results for a patient with inflammatory bowel disease (IBD). This service is commonly performed before initiating immunosuppressive or biologic therapies for IBD or as part of routine disease management. National attention to this code reflects the clinical importance of identifying latent or active TB in immunocompromised populations to prevent reactivation and transmission. Payers commonly evaluate documentation and clinical context when adjudicating claims for screening and interpretation services.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn how CPT code 3510F is defined and applied in clinical practice, the typical sites of service for this screening, and where documentation is expected in the medical record. The publication also covers common billing and policy considerations, documentation benchmarks, and how payers approach coverage and medical necessity for TB screening in IBD patients. Data not available in the input is noted where relevant, including payer-specific modifiers, associated taxonomies, ICD-10 pairings, and related billing codes.
Billing Code Overview
CPT code 3510F documents that the provider screened a patient with inflammatory bowel disease (IBD) for tuberculosis (TB) and interpreted the results. This code reflects documentation that TB screening occurred and that the clinician reviewed and recorded the screening outcome in the medical record.
-
Service type: TB screening and interpretation related to management of inflammatory bowel disease
-
Typical site of service: Outpatient clinic or ambulatory care setting where IBD patients receive routine evaluation and pre-treatment screening
Clinical & Coding Specifications
Clinical Context
A 34-year-old patient with known inflammatory bowel disease (for example, Crohn disease or ulcerative colitis) is seen in an outpatient gastroenterology clinic prior to initiation of a biologic or immunosuppressive therapy. The clinician documents a tuberculosis screening test (either a tuberculin skin test or interferon-gamma release assay) and records interpretation of the result in the medical record. The workflow includes review of prior tuberculosis testing, performance or ordering of the test, documentation of risk factors (history of BCG, prior TB exposure, travel, or immunosuppression), interpretation as negative, positive, or indeterminate, and any follow-up plan such as chest radiograph referral or infectious disease consultation. Typical site of service is an outpatient clinic or ambulatory infusion center where biologic therapy is managed.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
25 | Significant, separately identifiable evaluation and management service by the same physician on the day of a procedure | Use when a distinct E/M is performed the same day as TB screening documentation and it meets E/M criteria |
59 | Distinct procedural service |
