Z0100B. Medicare Part A: Version code, Step-by-Step

Step-by-Step Coding Guide for Item Set Z0100B: Medicare Part A: Version Code

1. Review of Medical Records

• Begin with a thorough examination of the facility's Medicare billing and MDS submission records.
• Identify the version of the RUG-IV grouper software or any relevant MDS assessment tool that was used to calculate the HIPPS code for the resident's current billing period.

2. Understanding Definitions

• Version Code: A code that indicates the version of the RUG-IV grouper software used to generate the HIPPS code. This code is essential for ensuring that the reimbursement claim matches the grouper version recognized by Medicare for that specific assessment period.

3. Coding Instructions

• Enter the correct version code corresponding to the RUG-IV grouper software used for the MDS assessment. This typically includes a version number and may also include a letter indicating a specific update or revision.

4. Coding Tips

• Always check for the most current version of the RUG-IV grouper software as updates may occur that affect the version code.
• Regularly communicate with your facility's billing department or software provider to confirm that the version of the grouper software in use is the latest and approved by Medicare.

5. Documentation

• Document the specific version of the RUG-IV grouper software used for each MDS assessment cycle in the resident's billing records.
• Maintain a log or database that records each assessment's date, the corresponding HIPPS code, and the version code used, to facilitate audits and reviews.

6. Common Errors to Avoid

• Using an outdated version code that no longer matches the current RUG-IV grouper software, which could lead to denied or delayed payments.
• Miscommunication between the MDS coordinators and the billing department regarding updates in the grouper software version.
• Failing to record the version code change in the resident's documentation when software updates are implemented.

7. Practical Application

• Example: During the quarterly MDS assessment period, the facility uses RUG-IV grouper software version 1.03.5b to calculate HIPPS codes. The Medicare Part A Version Code, "1.03.5b," is entered into Z0100B for each resident assessed during this period. This ensures that billing aligns with the software version authorized by Medicare for accurate reimbursement.
