Quick Explanation
This denial indicates that a hospice claim submitted for Continuous Home Care (CHC) under revenue code 0652 failed to meet the strict regulatory guidelines required to bill at this level of intensity. To qualify for CHC, the patient must be in an acute medical crisis, and the clinical documentation must prove that a minimum of 8 hours of care was provided within a 24-hour period, with more than 50% of that care delivered by a licensed nurse (RN or LPN). Failure to meet either the hourly threshold, the nursing percentage requirement, or the clinical definition of an acute crisis results in this denial.
Common Causes for HOS18
Denials with code HOS18 typically happen for the following specific reasons:
- Failing to document a minimum of 8 hours of direct, hands-on clinical care within a single 24-hour billing day (midnight to midnight).
- Failing to meet the statutory requirement that more than 50% of the continuous care hours must be provided by a registered nurse (RN), licensed practical nurse (LPN), or licensed vocational nurse (LVN).
- Lack of detailed clinical documentation establishing the existence of an active, acute medical crisis that would otherwise require inpatient hospitalization to manage.
- Improperly counting non-billable hours, such as staff travel time, administrative documentation time, or on-call standby time, toward the 8-hour continuous care minimum.
How to Prevent HOS18 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Enforce real-time EHR audits to verify that every day billed under revenue code 0652 has a minimum of 8 hours of direct clinical care documented.
- Utilize automated billing rules that calculate and verify that nursing hours (RN/LPN) constitute more than 50% of the total continuous care hours before claim submission.
- Educate clinical staff on the specific documentation requirements for a 'period of crisis,' ensuring they clearly record the acute symptoms, interventions, and patient outcomes.
- Implement a daily utilization review process during active CHC cases to immediately identify and resolve gaps in nursing coverage or documentation errors.

Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code HOS18: "Continuous care criteria not met".
We are appealing the denial of Continuous Home Care (CHC) services billed under revenue code 0652 for the dates of service [Insert Dates]. In accordance with the CMS Medicare Benefit Policy Manual (Pub. 100-02, Chapter 9, Section 40.2.1), CHC is covered during periods of crisis to maintain a terminally ill individual at home when acute symptom management is required. The enclosed clinical records demonstrate that the patient was in an acute medical crisis characterized by [Insert specific clinical symptoms, e.g., intractable pain, severe respiratory distress]. The detailed nursing logs confirm that a total of [Insert Number] hours of direct care was provided within the 24-hour billing period, with skilled nursing (RN/LPN) accounting for [Insert Percentage]% of the total hours, exceeding the 50% regulatory requirement. Because all billing and clinical criteria for continuous care were fully met and documented, we respectfully request that this denial be reversed and the claim be processed for payment.
Attached please find:
1. A copy of the original claim.
2. The relevant medical records supporting the service.
3. [Any other supporting documents].
We respectfully request that you reprocess this claim for payment.
