When can prolonged services be billed in relation to E/M codes?

Prolonged services can be billed on the same date as the primary service when they meet specific criteria. This involves additional face-to-face or non-face-to-face time spent as compared to the typical duration of the encounter. To qualify for billing prolonged services, documentation must reflect that the time spent exceeds what is typical for the chosen E/M code.

Billing for prolonged services on a different date than the primary service is not correct, as the nature of prolonged services is intrinsically linked to the initial encounter. The guidelines specify that this extra time should occur concurrently with the primary evaluation and management service to ensure continuity of care and accurate medical record documentation.

The option of only billing during follow-up appointments or if the service is performed by the same provider is also unaligned with the guidelines. Prolonged services do not have restrictions based on follow-up care situations or provider continuity. Rather, it encompasses additional time on that same day of service, as indicated by proper coding standards. Thus, the accurate understanding is that the prolonged services should always correspond to the same day as the primary service to justify the additional billing.
