The social security site shows that my start date for benefits began on 5/09, but I did not receive my first check until 6/09. Was that check for May or June? If June, does that mean my start date was June 2009 rather than May 2009 or is the benefit payment always a month behind?
When a Medicare contractor receives a claim with an unlisted HCPCS code for non-OPPS payment, the contractor shall verify that no existing HCPCS code adequately describes the procedure or service. Unlisted codes should be reported only if no other specific HCPCS codes adequately describe the procedure or service.
NEC is the equivalent to using an other code selection and NOS is the equivalent to using an unspecified code selection. Think of NEC as the code set's fault: The physician provides specific findings but the ICD-9-CM code set does not list a specific code that describes the diagnosis. On the other hand consider NOS the physician's fault: The documentation does not provide enough information to assign a more specific diagnosis code. NEC codes are frequently highlighted in gray in the ICD-9 manual and NOS codes are usually highlighted in yellow. An example of when you would use an NEC code: The physician specifies spinal nerve root compression. You look in the 724.x category - Other and unspecified disorders of back - for the appropriate code.
