I0100: Cancer (With or Without Metastasis), Step-by-Step

Step-by-Step Coding Guide for Item Set I0100: Cancer (With or Without Metastasis)

1. Review of Medical Records

• Objective: Accurately determine and document whether the resident has a diagnosis of cancer, either with or without metastasis.
• Steps:
  1. Collect Information: Review the resident’s comprehensive medical records, including physician notes, oncology reports, diagnostic imaging, laboratory results, and previous assessments.
  2. Identify Documentation of Cancer: Look for documented instances of cancer diagnosis, specifying the type of cancer and whether metastasis is present.
  3. Confirm Details: Verify the consistency and accuracy of the documentation across various sources within the medical records.

2. Understanding Definitions

• Cancer: A broad group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body.
• Metastasis: The spread of cancer cells from the place where they first formed to another part of the body.
• Key Points:
  • Cancer can affect any part of the body and may be localized or metastatic.
  • Diagnosis of cancer should be confirmed by a physician and documented in the medical records.

3. Coding Instructions

• Steps:
  1. Identify Relevant Documentation: Confirm through the medical records if the resident has been diagnosed with cancer.
  2. Verify Documentation: Ensure that the diagnosis of cancer, along with any information about metastasis, is clearly noted in the records.
  3. Code Appropriately: Enter the code for cancer in item set I0100:
     • 1: Yes, the resident has a diagnosis of cancer (with or without metastasis).
     • 0: No, the resident does not have a diagnosis of cancer.

4. Coding Tips

• Accurate Identification: Ensure the diagnosis of cancer is correctly identified and supported by relevant documentation.
• Consistent Terminology: Use consistent terminology and phrasing when documenting and coding the resident’s diagnosis of cancer.
• Clarify with the Resident: If there is any uncertainty, clarify with the resident or their legal representative to ensure accurate coding.

5. Documentation

• Required:
  • Physician Notes: Detailed notes from physicians documenting the diagnosis of cancer, including type and stage.
  • Oncology Reports: Reports from oncologists detailing the diagnosis, treatment plan, and any metastasis.
  • Diagnostic Imaging: Imaging reports that confirm the presence and extent of cancer.
  • Laboratory Results: Lab reports that support the diagnosis, such as biopsy results or tumor markers.
  • Previous Assessments: Any previous assessments that have documented the resident’s diagnosis of cancer.

6. Common Errors to Avoid

• Misclassification: Ensure accurate classification by verifying the diagnosis of cancer through multiple records and notes.
• Incomplete Documentation: Make sure all relevant physician notes, oncology reports, and diagnostic imaging are included to support the diagnosis.
• Assumptions: Do not assume the resident has cancer without proper documentation and verification; always check multiple sources.

7. Practical Application

• Example:
  • Resident Profile: Mary, a 70-year-old resident, has been diagnosed with breast cancer with metastasis to the bone.
  • Steps:
    1. Review Records: The nurse reviews Mary’s medical records, noting the physician notes, oncology reports, and diagnostic imaging documenting the cancer diagnosis.
    2. Identify Diagnosis: It is confirmed through the documentation that Mary has breast cancer with metastasis to the bone.
    3. Document and Code: The nurse documents the diagnosis details in Mary’s records and codes I0100 as "1".
  • Outcome: Mary’s diagnosis of cancer is accurately documented and coded, ensuring proper follow-up and care planning.
