LOC is just one within many signals your manager and organization should use in their review. If you have low LOC because the project was in chaos, or was still being designed and organized, etc... those would all be fine justifications to me as a manager. In fact, those would be problems for me to solve -- to make sure you are in an environment where you are able to be productive. If, on the other hand, you were on a "smooth sailing" project, and didn't have any code delivered in the last month, that would be a red flag to me, which we would need to talk about.
