Quick Explanation
Denial code CO 196 occurs when a claim is submitted for a patient who is currently enrolled in a hospice program, but the services were billed outside of the hospice benefit. Under CMS guidelines, once a patient elects hospice, all care related to their terminal illness is covered under the hospice per diem rate, resulting in denials for external claims that fail to utilize the appropriate hospice-exclusion modifiers.
Common Causes for CO 196
Denials with code CO 196 typically happen for the following specific reasons:
- Billing for services unrelated to the terminal illness without appending the required GW modifier.
- Bypassing hospice coordination when the physician is acting as the designated attending physician but fails to append the GV modifier.
- Services rendered by a non-hospice provider that are determined to be clinically related to the patient's terminal hospice diagnosis.
- A lag in updating the patient's hospice revocation or discharge status in the payer's eligibility database.
How to Prevent CO 196 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Implement real-time eligibility verification checks at registration to identify patients with an active hospice election period.
- Train billing staff to append modifier GW (service unrelated to terminal condition) or modifier GV (attending physician not employed by hospice) on eligible claims.
- Establish clinical coordination workflows with local hospice agencies to clarify treatment relationship to the terminal illness before submitting claims.
- Review and verify hospice discharge or revocation dates when claims span hospice transition periods to ensure correct billing alignment.

Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code CO 196: "Hospice denial code".
We are appealing the denial under code CO 196 for services rendered on [Date of Service]. While the patient was enrolled in a hospice program at the time of service, the medical documentation clearly demonstrates that the treated condition, [Insert Non-Terminal Diagnosis/ICD-10 Code], is clinically distinct and entirely unrelated to the patient's terminal hospice diagnosis of [Insert Terminal Diagnosis]. Pursuant to the Medicare Claims Processing Manual, Chapter 11, Section 40.1, providers are entitled to reimbursement for unrelated care when submitted with modifier GW, which was appropriately appended to this claim. We respectfully request that you review the attached medical records and reprocess this claim for immediate 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.
