Quick Explanation
Denial code HP1 indicates that the payer has denied the claim because the submitted medical documentation does not sufficiently support a terminal diagnosis or a life expectancy of six months or less, which is required for hospice or palliative care benefits. This typically occurs when clinical evidence fails to demonstrate a progressive, terminal decline in the patient's condition according to specific coverage criteria.
Common Causes for HP1
Denials with code HP1 typically happen for the following specific reasons:
- Missing, incomplete, or late physician certification of terminal illness (COI) that fails to meet CMS mandated timeframes.
- Lack of objective clinical documentation demonstrating terminal trajectory, such as failure to document functional decline (e.g., Karnofsky Performance Status or FAST scale for dementia).
- The primary diagnosis code reported on the claim does not align with Local Coverage Determination (LCD) guidelines for hospice eligibility.
- Contradictory clinical notes within the medical record suggesting the patient's condition has stabilized or improved rather than declined.
How to Prevent HP1 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Establish a strict pre-billing review process to verify that the physician's terminal illness certification is fully completed, signed, and dated prior to claim submission.
- Train clinical and documentation teams to record specific, quantifiable decline metrics, such as weight loss, recurring infections, and declining laboratory values, that support the terminal prognosis.
- Utilize diagnosis-specific templates within the EHR to prompt clinicians to document all necessary LCD criteria for non-cancer diagnoses like heart disease or dementia.
- Conduct regular interdisciplinary group (IDG) record reviews to ensure consistent documentation of the terminal decline across all attending providers and nursing staff.

Denial Code: HP1 - Terminal diagnosis not supported
Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code HP1: "Terminal diagnosis not supported".
We are appealing the denial of this claim under code HP1 (Terminal diagnosis not supported). In accordance with the Medicare Benefit Policy Manual, Chapter 9, Section 10, hospice services are covered for individuals certified as terminally ill with a life expectancy of six months or less if the terminal illness runs its normal course. The enclosed medical documentation demonstrates a clear and consistent clinical decline, including objective measurements such as [Insert clinical indicators, e.g., significant weight loss, declining FAST score, or recurrent hospitalizations] which fully satisfy the Local Coverage Determination (LCD) guidelines for terminal prognosis. Because the contemporaneous clinical records unequivocally support the terminal diagnosis, we respectfully request that this denial be overturned and the claim be approved 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.
Sincerely,
[Your Name]
