One of the quoted conditions for EN/PN coverage specifies that the impairment must be permanent for a duration of at least how long?

• A. 1 month
• B. 3 months
• C. 6 months
• D. 12 months

Answer: (B)

Understanding EN/PN coverage requires recognizing that the impairment must be a lasting, ongoing need. The minimum duration commonly used is three months. This threshold distinguishes temporary, reversible illness from a true, long-term requirement for nutrition support. A shorter period, like one month, could include conditions that are simply transient and don’t justify long-term EN/PN. A longer period, such as six or twelve months, would be stricter than necessary for many patients who truly require ongoing support. So, the best answer reflects the policy intent: the impairment must be permanent and expected to last at least three months. In practice, other factors like prognosis, functional status, and recovery potential also influence coverage decisions.
