(from CMS Manual System - Pub 100-04 Medicare Claims Processing - Transmittal 1104)
FL 67 - Principal Diagnosis Code Required. The hospital enters the ICD code for the principal diagnosis. The code must be the full ICD diagnosis code, including all five digits where applicable. The reporting of the decimal between the third and fourth digit is unnecessary because it is implied. The principal diagnosis code will include the use of “V” codes. Where the proper code has fewer than five digits, the hospital may not fill with zeros. The principal diagnosis is the condition established after study to be chiefly responsible for this admission. Even though another diagnosis may be more severe than the principal diagnosis, the hospital enters the principal diagnosis. Entering any other diagnosis may result in incorrect assignment of a DRG and cause the hospital to be incorrectly paid under PPS. The hospital reports the full ICD code for the diagnosis shown to be chiefly responsible for the outpatient services in FL 67 of the bill. It reports the diagnosis to its highest degree of certainty. For instance, if the patient is seen on an outpatient basis for an evaluation of a symptom (e.g., cough) for which a definitive diagnosis is not made, the symptom must be reported (7862). If during the course of the outpatient evaluation and treatment a definitive diagnosis is made (e.g., acute bronchitis), the hospital must report the definitive diagnosis (4660). When a patient arrives at the hospital for examination or testing without a referring diagnosis and cannot provide a complaint, symptom, or diagnosis, the hospital should report an ICD code for Persons Without Reported Diagnosis Encountered During Examination and Investigation of Individuals and Populations (V70-V82). Examples include: • Routine general medical examination (V700); • General medical examination without any working diagnosis or complaint, patient not sure if the examination is a routine checkup (V709); and • Examination of ears and hearing (V721). NOTE: Diagnosis codes are not required on nonpatient claims for laboratory services where the hospital functions as an independent laboratory.
FLs 67A-67Q - Other Diagnosis Codes Inpatient Required. The hospital enters the full ICD codes for up to eight additional conditions if they co-existed at the time of admission or developed subsequently, and which had an effect upon the treatment or the length of stay. It may not duplicate the principal diagnosis listed in FL 67 as an additional or secondary diagnosis. If the principal diagnosis is duplicated, the FI will remove the duplicate diagnosis before the record is processed by GROUPER for IPPS claims. The MCE identifies situations where the principal diagnosis is duplicated for IPPS claims. Outpatient - Required. The hospital enters the full ICD codes in FLs 67A-67Q for up to eight other diagnoses that co-existed in addition to the diagnosis reported in FL 67. NOTE: Medicare will ignore data submitted in 67I – 67Q.
FL 69 - Admitting Diagnosis Required. For inpatient hospital claims subject to QIO review, the admitting diagnosis is required. Admitting diagnosis is the condition identified by the physician at the time of the patient’s admission requiring hospitalization. This definition is not the same as that for SNF admissions.
