Processing Requirements

13. Bilateral Procedure 
There are codes that do not accurately reflect performed procedures in one admission on two or more different bilateral joints of the lower extremities. A combination of these codes show a bilateral procedure when, in fact, they could be single joint procedures (i.e., duplicate procedures). 

If two more of these procedures are coded, and the principal diagnosis is in MDC 8, the claim is flagged for post-pay development. The A/B MAC (A) processes the bill as coded but requests an O.R. report. If the report substantiates bilateral surgery, no further action is necessary. If the O.R. report does not substantiate bilateral surgery, an adjustment bill is processed. 

If the error rate for any provider is sufficiently high, the A/B MAC (A) may develop claims prior to payment on a provider-specific basis. 

Effective with the implementation of ICD-10, ICD-10-PCS codes will be implemented which clearly identify the exact joint (left or right). Reporting these two more precise ICD-10-PCS codes will clearly indicate if a bilateral procedure is performed.

14. Invalid Age 
If the hospital reports an age over l24, the A/B MAC (A) requests the hospital to determine if it made a bill preparation error. If the beneficiary's age is established at over l24, the hospital enters 123. 

15. Invalid Sex 
A patient's sex is sometimes necessary for appropriate MS-DRG determination. Usually the A/B MAC (A) can resolve the issue without hospital assistance. The sex code reported must be either 1 (male) or 2 (female). 

16. Invalid Discharge Status 
A patient's discharge status is sometimes necessary for appropriate MS-DRG determination. Discharge status must be coded according to the Form CMS-1450 conventions.

 17. Invalid Discharge Date 
An invalid discharge date is a discharge date that does not fall into the acceptable range of numbers to represent, either the month, day or year (e.g., 13/03/01, 12/32/01). If no discharge date is entered, it is also invalid. MCE reports when an invalid discharge date is entered. 

18. Limited Coverage 
Effective October 1, 2003, for certain procedures whose medical complexity and serious nature incur extraordinary associated costs, Medicare limits coverage. The edit message indicates the type of limited coverage (e.g., LVRS, heart transplant, etc). The procedures receiving limited coverage edits previously were listed as non-covered procedures, but were covered under Medicare in certain circumstances. The A/B MACs (A) will handle these procedures as they had previously. 

19. Procedure inconsistent with length of stay 
The following procedure code should only be coded on claims when the respiratory ventilation is provided for greater than four consecutive days during the length of stay. Effective October 1, 2012, ICD-9-CM procedure code, 96.72, Continuous invasive mechanical ventilation for 96 consecutive hours or more Effective October 1, 2015, ICD-10-PCS code, 5A1955Z - Respiratory Ventilation, Greater than 96 Consecutive Hours
