Quick Explanation
This denial occurs when a payer determines that the clinical documentation fails to sufficiently demonstrate the active administration, necessity, or escalation of comfort care (palliative) measures required for the billed level of service. It typically arises in hospice or inpatient palliative care settings where the medical record does not adequately detail the complex symptom management or end-of-life interventions necessary to justify the reimbursement rate.
Common Causes for HOS22
Denials with code HOS22 typically happen for the following specific reasons:
- Lack of daily clinical documentation detailing active, complex symptom management or adjustments to palliative medication regimens.
- Billing for General Inpatient (GIP) hospice care when the documentation only supports routine home care or baseline comfort measures that could be managed in a lower-acuity setting.
- Failure to document the specific, acute clinical crisis or intractable symptoms (e.g., severe pain, respiratory distress, terminal agitation) that necessitated intensive comfort care.
- Inadequate documentation of interdisciplinary team (IDT) involvement or updates to the palliative plan of care reflecting the patient's escalating needs.
How to Prevent HOS22 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Ensure detailed, daily charting of all comfort care measures, including specific pain/symptom scale assessments, medication titrations, and response to interventions.
- Train clinical and billing staff on CMS Medicare Benefit Policy Manual Chapter 9 guidelines regarding the stringent documentation required to justify high-acuity hospice and palliative services.
- Implement pre-bill auditing protocols to verify that the clinical severity recorded in the patient chart directly aligns with the level of comfort care billed.
- Ensure the Interdisciplinary Group (IDG) plan of care is updated in real-time to clearly reflect the clinical rationale for the intensive comfort care interventions provided.

Denial Code: HOS22 - Comfort care measures insufficient
Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code HOS22: "Comfort care measures insufficient".
We are appealing the denial of claim code HOS22, as the clinical documentation clearly supports that intensive comfort care measures were both medically necessary and actively managed during the billed period. Pursuant to CMS Medicare Benefit Policy Manual Chapter 9, Section 40, higher levels of palliative and hospice care are warranted for acute symptom management and pain control that cannot be managed in a routine setting. The enclosed medical records detail [insert specific clinical details, e.g., aggressive medication titration, continuous nursing assessments, or management of intractable respiratory distress], demonstrating that comfort care measures were comprehensive, continuously monitored, and fully documented by the clinical team. Because the documentation meets all federal and clinical guidelines for the billed level of service, we respectfully request that this denial be overturned and the claim be paid in full.
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.
Sincerely,
[Your Name]
