Other Diagnoses include all conditions that coexist at the time of inpatient admission or ambulatory surgical service, or develop subsequently, which affect the treatment received and/or length of stay. Diagnoses that relate to an earlier episode which have no bearing on the current stay are to be excluded.

Conditions should be coded that affect patient care in terms of requiring: clinical evaluation, therapeutic treatment, diagnostic procedures, extended length of stay, or increased nursing care and/or monitoring.

Codes and Values:

  1. Must be valid ICD-9-CM code. To be valid, ICD-9-CM codes must be entered at the most specific level to which they are classified in the ICD-9-CM Tabular List. Three-digit codes further divided at the four-digit level must be entered using all four digits. Four-digit codes further subclassified at the five-digit level must be entered using all five digits. Failure to enter all required digits in the diagnosis codes will cause the record to be rejected.

  2. E-codes are valid as Other Diagnosis Codes.

  3. Must be entered exactly as shown in the ICD-9-CM coding reference.

  4. Inpatient Only (prior to 1/1/99):
    Only E-codes in the range of E930.0 - E949.9 are valid as Other Diagnosis Codes. Other E-codes are to be reported in External Cause-of-Injury Code and Place-of-Injury Code.

  5. If this field is not applicable it must contain blanks.

Edit Applications:

  1. Edits pertaining to ICD-9-CM codes are validated on the basis of the Statement-Covers-Thru Date or Expected Principal Reimbursement depending on conditions described in Appendix N , which include age-specific and sex-specific diagnosis code conditions.

  2. When the edit flag on the ICD-9-CM reference file for an "unacceptable principal/primary diagnosis without a secondary diagnosis" is applicable for the Principal/Primary Diagnosis Code, an Other Diagnosis Code 1-14 must also be reported.

  4. Inpatient Only:
    If an Other Diagnosis Code 1-14 is reported, the corresponding Present on Admission Indicator must also be reported except for E-codes.
