The Medicare laboratory negotiated NCDs include some general coding guidelines applicable to all of the NCDs. In addition, some NCDs, such as Urine Culture, Bacterial, contain additional guidelines applicable exclusively to that NCD. Several of the ICD-9-CM codes in the urine culture coding guideline number 1 have been superseded by annual updates to the ICD-9-CM diagnosis codes and the guideline is now out of date. We are soliciting public comment regarding updating of this coding guideline.
