CMS Pub. 100-08, ch. 10, § 10.4.1.3.5

If, in the contractor’s view, the provider failed to submit all of the requested data/documentation

and/or a valid certification statement if required (e.g., as a correction to the original certification

statement, as part of a request for missing data, etc.), the contractor may:

• Reject the application if the 30-day period has elapsed,

• Wait until the 30-day period has elapsed and then reject the application, or

• Extend the 30-day period no more than an additional 30 days if (1) it appears that the

provider is making a good-faith effort to comply with the development letter and/or (2) the

provider furnished most of the requested data. For instance, suppose the contractor requested 5

pieces of clarifying information. The provider timely submitted 4 of them and furnished a signed

certification statement. Since the provider appears to be acting in good faith, the contractor is

encouraged to continue working with the provider.

If the provider fails to fully respond to a second request, the contractor may either: (1) reject the

application if the original 30-day period has elapsed, (2) wait until the 30-day period has elapsed

and then reject the application, or (3) make a third request using the procedures described above.
