Target: Short Stays


The descriptions listed are the most succinct and specific yet to be posted by any RAC. For medical necessity, the description reads as follows, with each code inserted as appropriate:


“RACs will review documentation to validate the medical necessity of short stay, uncomplicated admissions of MS DRG [XXX]. Medicare only pays for inpatient hospital services that are medically necessary for the setting billed and that are coded correctly. Medical documentation will be reviewed to determine that the services were medically necessary and were billed correctly.” (Emphasis added.)


For those MS-DRGs approved for both medical necessity and DRG Validation, an additional paragraph is included after the above mention of medical necessity:


“RACs WILL ALSO REVIEW documentation for DRG Validation requiring that diagnostic and procedural information and the discharge status of the beneficiary, as coded and reported by the hospital on its claim, matches both the attending physician description and the information contained in the beneficiary’s medical record. Reviewers will validate for MS-DRG, principal diagnosis, secondary diagnosis, and procedures affecting or potentially affecting the DRG.” (Emphasis original.)


This description mirrors previous language used in other postings for approval of DRG Validation, except for the previous exclusion of the review of medical necessity.


Plus More DRG Validations


In addition to the 18 new issues posted for medical necessity, Connolly posted 32 other new DRGs as approved for validation (medical necessity excluded at this time):


*MSDRG 254: Other Vascular Procedures without CC/MCC

*MSDRG 314: Other Circulatory System Diagnoses W MCC

*MSDRGs 280, 281, 282, 283, 284, 285, 288, 289, 290, 292, 293, 296, 297, 298, 299, 300, 301, 302, 303, 304, 305, 306, 307, 308, 309, 310, 311, 313, 314, 316: Cardiovascular Diseases


No Edits to Existing Posts (Yet)


Previously listed MS-DRGs with approval for DRG Validation only, excluding medical necessity, neither have been edited nor removed from Connolly’s list as of 4 p.m. EST, Aug. 27.


The Connolly list includes neither the date of posting nor approval of their issues, nor do they include any internal issues “numbers” as seen on the other three RAC websites.
