Inpatient Service Specific Complex Review of Short Stays Diagnosis Related Group (DRG) for Esophagitis Gastroenteritis (DRG Codes 391 and 392)

The J15 Part A Medical Review department will perform a service-specific complex review on inpatient services for short stays related to Esophagitis Gastroenteritis (DRG Codes 391 - 392). A Service Specific Probe Edit was conducted. There were a total of 98 claims reviewed with 63 denied in Kentucky. The total charges were $350,456.41. The total denied charges were $212,803.06. That resulted in a charge denial rate of 60.7 percent.

There were a total of 99 claims reviewed with 47 denied in Ohio. The total charges were $428,719.42. The total denied charges were $203,799.47. That resulted in a charge denial rate of 47.5 percent. Based on these high charge denial rates and total denied charges, this edit will progress to Complex Service Specific in both Kentucky and Ohio.

The top three denial reasons identified were:

Denial Code 5J504 - (Kentucky - 48.7 percent; Ohio - 43.2 percent)

      • Submit documentation to support that all services were medically necessary on an impatient basis instead of a less intensive setting.
      • Documentation should include all clinical information for the dates of service billed such as physician progress notes, physical examinations, assessments, diagnostic tests and laboratory test results, history and physical, nurse's notes, consultations, surgical procedures, orders and discharge summary and any other documentation to support the inpatient admission.

Denial Code 56900 - (Kentucky - 11.9 percent; Ohio - 2.8 percent)

  • Reason for Denial
    • The medical records were not received in response to an ADR in the required time frame; therefore, we were unable to determine medical necessity
  • How to Avoid a Denial
    • Monitor your claim status on Direct Data Entry (DDE). If the claim is in status/location SB6001, the claim has been selected for review and records must be submitted. Note: Records may be requested by the Medical Review department, the Claims department, Zone Program Integrity Contractors (ZPIC), etc. Ensure the records are submitted to the appropriate entity.
    • Alert your mail staff to be aware of any mail you receive from CGS
    • Be aware of the need to submit medical records within 30 days of the date on the ADR in the upper left corner
    • Gather all information and submit at one time
    • Submit medical records as soon as the ADR is received
    • Attach a copy of the ADR to each individual claim
    • If responding to multiple ADR's, separate each response and attach a copy of the ADR to each individual set of medical records. Ensure each set of medical records is bound securely so the submitted documentation is not detached or lost.
    • Do not mail packages COD; we can not accept them
    • Return the medical records to the address indicated in the ADR. Be sure to include the appropriate mail code.

Denial Code 5J503 - (Kentucky - 0.1 percent; Ohio - 1.5 percent)

  • Reason for Denial
    • The documentation submitted for review did not include a physician's order to admit the patient. Please review medical records prior to billing to assure the level of care billed is consistent with the level of care ordered. Services that are not ordered by the physician are not reasonable and necessary.
  • How to Avoid a Denial
    • Physician's order to admit to inpatient services should be clearly identified in the medical records. This order may be located within the history and physical, progress note, emergency room report and/or verbal order signed and dated by the physician.
    • The signature must be legible and should include the practitioner's first and last name. Also include applicable credentials such as MD, PA or DO.
    • Electronic signatures are acceptable.
    • Orders for inpatient admission written by a non-physician practitioner must be co-signed by the attending physician
