Step-by-Step Coding Guide for Item Set A1550A: ID/DD Status: Down Syndrome

1. Review of Medical Records

• Objective: Ensure accurate coding by thoroughly reviewing the resident's medical history and current medical status.
• Steps:
  1. Gather Medical Records: Collect all relevant medical records, including physician notes, diagnosis lists, and any previous assessments.
  2. Identify Documentation: Look for specific documentation that confirms a diagnosis of Down syndrome.
  3. Confirm Diagnoses: Verify that Down syndrome is listed as a diagnosis in the medical records.

2. Understanding Definitions

• Intellectual Disability (ID)/Developmental Disability (DD): A group of conditions due to an impairment in physical, learning, language, or behavior areas.
• Down Syndrome: A genetic disorder caused by the presence of an extra chromosome 21, which leads to developmental and intellectual delays.

3. Coding Instructions

• Steps:
  1. Locate Item Set: Find item set A1550A on the MDS form.
  2. Determine Presence: Confirm whether the resident has a diagnosis of Down syndrome.
  3. Select the Appropriate Code:
     • Code 1: Yes, if the resident has Down syndrome.
     • Code 0: No, if the resident does not have Down syndrome.
  4. Record the Code: Enter the selected code in the designated field on the MDS form.

4. Coding Tips

• Accuracy: Ensure the diagnosis of Down syndrome is explicitly stated in the medical records.
• Consistency: Verify that the diagnosis of Down syndrome is consistent across all medical records and assessments.
• Detail: Include comprehensive details in the documentation to support the diagnosis.

5. Documentation

• Required:
  • Physician Notes: Notes from healthcare providers confirming the diagnosis of Down syndrome.
  • Diagnosis Lists: Updated lists of diagnoses that include Down syndrome.
  • Assessment Records: Any formal assessments or evaluations that mention Down syndrome.

6. Common Errors to Avoid

• Incorrect Coding: Double-check to ensure the correct code (1 or 0) is entered based on the presence or absence of Down syndrome.
• Incomplete Documentation: Ensure all relevant details supporting the diagnosis of Down syndrome are included in the medical records.
• Misinterpretation: Avoid assuming a diagnosis without explicit confirmation in the medical records.

7. Practical Application

• Example: A resident's medical records include multiple confirmations from physicians stating that the resident has Down syndrome.
  • Coding: The MDS form should reflect a code of 1 under item set A1550A.
• Illustration:
  • Medical Record Entry: A physician’s note stating, "Resident has Down syndrome, confirmed by genetic testing."
  • MDS Entry: The coder marks 1 for A1550A on the MDS form.
