M0300C1. Stage 3 pressure ulcers: number present, Step-by-Step

Step-by-Step Coding Guide for Item Set M0300C1: Stage 3 Pressure Ulcers

1. Review of Medical Records

• Thoroughly review the resident’s medical records, focusing on nursing and wound care team assessments, physician notes, and any relevant hospital transfer documents for indications of pressure ulcer presence and staging upon admission and throughout the care period.

2. Understanding Definitions

• Stage 3 Pressure Ulcer: This stage is characterized by full-thickness skin loss involving damage or necrosis of subcutaneous tissue that may extend down to, but not through, underlying fascia. The ulcer presents as a deep crater with or without undermining of adjacent tissue.

3. Coding Instructions

• For M0300C1, code the total number of Stage 3 pressure ulcers currently present. Verify each wound meets the Stage 3 criteria before coding.

4. Coding Tips

• Distinguish between Stage 3 and other stages carefully, noting the extent of tissue involvement and the presence of necrotic tissue. Stage 3 should not involve muscle or bone exposure—that would indicate a Stage 4 pressure ulcer.

5. Documentation

• Document each Stage 3 pressure ulcer's location, size, depth, presence of tunneling or undermining, wound bed condition, and any necrotic tissue. Note changes in the ulcer’s condition and the treatment plan.

6. Common Errors to Avoid

• Misclassifying ulcer stages, especially confusing Stage 3 with Stage 4 or deep tissue injury.
• Overlooking the development of new ulcers or progression in existing ulcer stages.

7. Practical Application

• Use case studies for training purposes, focusing on accurate assessment and documentation. Regularly review and update care plans based on the current status of each pressure ulcer.

Please note that the information provided in this guide for MDS 3.0 Item M0300C1: Type of Record was originally based on the CMS's RAI Version 3.0 Manual, October 2023 edition. Every effort will be made to update it to the most current version. The MDS 3.0 Manual is typically updated every October.
