The American Academy of Sleep Medicine (AASM) has sent a letter to the National Correct Coding Initiative (NCCI), which is part of the Centers for Medicare and Medicaid Services (CMS), regarding the G0400 code. 

One final point made by the AASM is confusion regarding the addition of G0399, which is identical to CPT code 95806. The proposed G code has a definition identical to 95806, which will be retained as a code, and the AASM requested clarification regarding the rationale behind this duplication.

On Friday, June 6, 2008, Itamar is presenting an application for a Level III code to the CPT Editorial Panel. The AASM has indicated its support for a Level III code for WatchPat. A Level III code is for emerging technology and is not assigned a value for reimbursement. The AASM will inform members of the outcome of the CPT Editorial Panel.

G codes are Medicare-specific codes that are typically used by CMS for reporting services under conditions unique or particular to the Medicare program. G codes are generally not recognized by other payers.

One concern the AASM has maintained and still views as problematic is the lack of definition for parameters that must be measured for a Type IV portable test. G0400 does not define the parameters required; the ambiguity creates a code that is unclear and potentially detrimental to quality patient care.

The AASM also offered comment regarding billing of other G codes on the same day as the billing for a sleep code.
