CMS received an external request to add ICD-9-CM code 158.9—Malignant neoplasm of peritoneum, unspecified—as a covered indication for the national coverage determination (NCD) on Human Chorionic Gonadotropin (hCG) at section 190.27 of the Medicare National Coverage Determination Manual (NCDM).
Section 190.27 of the NCDM states that hCG is “useful for monitoring and diagnosis of germ cell neoplasms of the ovary, testis, mediastinum, retroperitoneum, and central nervous system.”
We believe that the ICD-9-CM code 158.9—Malignant neoplasm of peritoneum, unspecified—may flow from this narrative.
We seek public comments on the request to add code 158.9 to the list ICD-9-CM Codes Covered By Medicare for the hCG NCD.
CMS, in conjunction with committees of stakeholders, used a negotiated rulemaking process to develop NCDs that cover 23 distinct diagnostic laboratory services under a negotiated rulemaking process. These final NCDs were published in 2001. For each of these 23 laboratory services, CMS listed the ICD-9-CM diagnosis codes and the CPT/HCPCS procedure codes for which Medicare provides coverage.
Since 2001, CMS has received requests to revisit these diagnosis and/or procedure code lists. To accommodate these requests, CMS established an abbreviated administrative process for considering these coding change requests. This process is known as the “Coding Analysis for Labs (CALs)” process. CMS describes this CAL process in a Federal Register notice, which was published on February 25, 2005, and is available online at http://www.cms.hhs.gov/CoverageGenInfo/04_LabNCDs.asp#TopOfPage.
Because the hCG NCD is one of these 23 NCDs, and because we believe that the code referenced above may flow from the NCD narrative, we are conducting this analysis under the abbreviated CAL process.
