Clinical & Coding Specifications
Clinical Context
A 35-year-old adult presents to a primary care clinic during influenza season requesting routine immunizations. The clinician documents a standard preventive visit, verifies immunization history, screens for contraindications (egg allergy, anaphylaxis history, acute febrile illness), and obtains verbal consent. The patient receives a single intramuscular 0.5 mL dose of the preservative-free, split-virus quadrivalent influenza vaccine (CPT 90686) in the deltoid. Post-vaccination observation for 15 minutes is provided for routine monitoring for adverse reaction. The encounter includes vaccine administration only; no additional medically necessary evaluation and management services are billed separately unless distinct and documented.
Coding Specifications
| Modifier | Description | When to Use |

25 | Significant, separately identifiable E/M service on the same day as procedure | Use when a documented independent evaluation and management visit is performed in addition to CPT 90686 (e.g., acute complaint requiring workup distinct from vaccination). |
