Clinical & Coding Specifications
Clinical Context
A deaf adult patient arrives for a scheduled primary care visit to address uncontrolled diabetes and medication reconciliation. The clinic schedules a certified sign language interpreter to be present for communication throughout the 30-minute visit. The interpreter documents two 15-minute units of interpretive services billed as T1013 (sign language or oral interpretive services, per 15 minutes). The clinical workflow: the medical assistant confirms the need for interpretation at check-in, the scheduler arranges an in-person or remote interpreter, the interpreter logs start and stop times in 15-minute increments, clinical staff conduct the history, exam, and counseling with the interpreter facilitating communication, and the billing team submits T1013 with appropriate modifiers and diagnosis linkage to the patient’s primary condition for the encounter.
Coding Specifications
