Z0100A: Medicare Part A: HIPPS Code, Step-by-Step

Step-by-Step Coding Guide for Item Set Z0100A: Medicare Part A: HIPPS Code

1. Review of Medical Records

• Objective: Ensure accurate and comprehensive documentation of the resident's Medicare Part A stay.
• Actions:
  • Access the resident’s medical records, focusing on the period covered by Medicare Part A, including the start and end dates.
  • Verify all information related to the Prospective Payment System (PPS) assessment is complete and accurate.

2. Understanding Definitions

• HIPPS Code: The Health Insurance Prospective Payment System (HIPPS) code is a five-character alphanumeric code used to determine payment rates for Medicare Part A services.
  • Z0100A: This field is used to record the HIPPS code that applies to the resident's Medicare Part A stay.
• PDPM: Patient-Driven Payment Model, which determines the HIPPS code based on various factors like clinical characteristics, functional status, and comorbidities.

3. Coding Instructions

• Step-by-Step:
  • Step 1: Review the PPS assessment data for the resident, including all necessary components such as functional status and clinical characteristics.
  • Step 2: Utilize the CMS software or other authorized tools to calculate the HIPPS code based on the PDPM classification.
  • Step 3: Enter the calculated HIPPS code into the Z0100A field in the MDS assessment form.
  • Step 4: Ensure that the HIPPS code aligns with the PPS assessment findings and the documented care provided during the Medicare Part A stay.

4. Coding Tips

• Consistency: Ensure that the HIPPS code is consistent with the clinical documentation and PPS assessment results.
• Validation: Use software tools to validate the HIPPS code before finalizing the MDS assessment to prevent errors.
• Regular Updates: Keep informed of any updates to the PDPM system or HIPPS code classification criteria.

5. Documentation

• Objective: Maintain detailed and accurate documentation to support the HIPPS code assigned.
• Actions:
  • Document the HIPPS code calculation process, including the inputs used from the resident’s assessment.
  • Ensure that all related documentation, such as therapy records and functional assessments, are complete and reflect the care provided during the Medicare Part A stay.

6. Common Errors to Avoid

• Incorrect HIPPS Code: Entering a HIPPS code that does not align with the PPS assessment results.
• Incomplete Assessment Data: Failing to include all necessary components in the PPS assessment, leading to an inaccurate HIPPS code.
• Failure to Validate: Not using available tools to validate the HIPPS code before submission.

7. Practical Application

• Example 1: A resident with a complex clinical condition requiring extensive rehabilitation services. The PPS assessment indicates a high level of care needs, resulting in a HIPPS code that reflects a higher payment rate. After calculating the HIPPS code using CMS tools, you enter it into Z0100A and verify that it aligns with the documented care.
• Example 2: A resident with a shorter Medicare Part A stay due to a planned discharge. The PPS assessment reflects lower care needs, and the corresponding HIPPS code indicates a lower payment rate. You ensure that the HIPPS code in Z0100A matches the assessment and discharge plan.

The Step-by-Step Coding Guide for item Z0100A in MDS 3.0 Section Z is based on the Long-Term Care Facility Resident Assessment Instrument 3.0 User’s Manual, Version 1.18.11, dated October 2023.
