LUPA stands for Low Utilization Payment Adjustment. In home health care, it’s a Medicare payment rule: if a patient’s 30-day care period has fewer visits than the required threshold, the agency’s payment is cut. Instead of getting the full 30-day episode payment, the home health agency is paid a lower per-visit rate. In other words, fewer visits than expected means a smaller total payment. (In the old 60-day payment system, any episode with 4 or fewer visits was a LUPA. Today under PDGM each 30-day period has its own threshold, typically between 2 and 6 visits.)

How LUPA Works

Under Medicare’s Patient-Driven Groupings Model (PDGM), home health care is paid in 30-day periods. Each period is assigned a case-mix group that comes with a visit threshold. If the total skilled visits (nursing, therapy, etc.) in that period fall below the threshold, the period is considered a LUPA and the agency is paid only at the lower per-visit rates. If visits meet or exceed the threshold, the agency receives the full case-mix adjusted payment for the 30-day episode. In practice:

• Threshold Range: Under PDGM, thresholds vary by case-mix group but always lie between 2 and 6 visits per 30-day period.
• Old vs. New: Before 2020, Medicare paid home health in 60-day episodes and any episode with 4 or fewer visits triggered LUPA. Now, each 30-day PDGM period has its own threshold. For example, one period might require 5 visits to avoid LUPA, while another might require only 3.
• Payment Impact: If a period becomes a LUPA, the agency’s payment is calculated by multiplying the wage-adjusted per-visit rate by the number of visits delivered. This almost always yields a much smaller total than the full episode payment.

For example, imagine a PDGM episode with a 5-visit threshold. If the patient receives all 5 visits, the agency gets the full 30-day payment for that case-mix. But if only 4 visits are provided, the entire period becomes a LUPA and the agency is paid at the lower per-visit rate. One home health example showed that missing just one visit (4 instead of 5) cut the agency’s reimbursement by over 50%. This dramatic drop is why agencies pay close attention to LUPA thresholds.

What Determines the LUPA Threshold?

Each patient’s LUPA threshold is set by their PDGM case-mix group, which reflects the patient’s condition and needs. Medicare uses several patient factors to determine this group – and thus the visit threshold – for each 30-day period. Key factors include:

• Clinical Grouping (Primary Diagnosis): The main reason the patient needs care (e.g. wound care, post-surgery, CHF management). Each clinical group has different typical care patterns.
• Admission Source & Timing: Whether the patient is coming from a hospital or nursing facility, or from the community, and whether this is an early period of care (soon after discharge) or a later period. Early post-hospital patients often have higher thresholds.
• Functional Impairment (OASIS Data): Medicare assesses the patient’s level of physical/functional limitation (using OASIS questions). Patients with greater impairment usually need more visits, raising the threshold.
• Comorbidities (Secondary Diagnoses): Additional health conditions can increase care complexity. PDGM adds a comorbidity adjustment (none/low/high) that can bump up the threshold.

These factors create one of PDGM’s 432 different case-mix groups, each with a set visit threshold. In plain terms, a very simple case might have a threshold of only 2–3 visits, while a more complex case might require 5–6 visits in the 30-day period to avoid a LUPA. In a nutshell: more complex or acute patients have higher LUPA thresholds under PDGM.

Why LUPA Matters

For a home health agency, LUPA episodes can have a big financial impact. Under PDGM, meeting the required number of visits is crucial. If an agency falls short, the payment for that period plunges, which can strain the agency’s revenue. Repeated LUPAs can quickly erode profits, especially since the per-visit payment often doesn’t fully cover care costs. In tight-margin home health work, each LUPA episode is a significant shortfall.

It’s not just money – LUPA rules also reflect Medicare’s goal that patients should get enough care up front. CMS expects that patients with greater needs will benefit from more visits early on, leading to better outcomes. In fact, CMS designed the PDGM model so that patients who typically need more care receive higher visit expectations. In other words, avoiding LUPA often goes hand-in-hand with delivering good patient care (more early visits can mean faster recovery).

Common reasons a LUPA gets triggered include: patient cancellations or refusals, staff shortages, or simply mis-scheduling visits. Even well-run agencies can get surprises – for example, a patient calls off a visit on Day 28 of a 30-day period, leaving the total count just below the threshold. In one analysis, patient cancellations (holidays, illness) and staff gaps were among the top causes of unintended LUPAs. An agency may be providing high-quality care, but if the visit count falls short, Medicare’s system automatically applies the LUPA adjustment.

Preventing LUPA Episodes

Because LUPAs can cut payments so drastically, agencies often develop systems to avoid them whenever possible. Key strategies include:

• Accurate Assessments & Coding: Perform the initial OASIS and care plan right away. Accurate functional scores and diagnosis codes help ensure the LUPA threshold is set correctly from the start.
• Schedule to the Threshold: Build care plans that meet or slightly exceed the predicted visit count. For example, if the threshold is 5, plan 6 visits (a “+1 buffer”) in case of any cancellations.
• Front-Load Visits When Appropriate: If the plan allows, concentrate visits earlier in the 30-day period. This way, last-minute changes or missed visits are less likely to drop you below the threshold.
• Monitor Visits in Real-Time: Track completed vs. planned visits daily or weekly. If a visit is missed, try to reschedule it quickly within the period. Some agencies set up alerts if an episode is approaching its visit threshold.
• Adjust Plans as Needed: If a patient’s condition changes (worsens or improves), get updated orders. A change in frequency might raise or lower the needed threshold.
• Communicate With Patients: Educate patients and families about the care plan schedule. If they understand the importance of each visit, they may be less likely to cancel without notice.

By staying aware of LUPA thresholds and having processes to respond when visits fall behind, agencies protect their reimbursement and ensure patients get the intended level of care. In short, LUPA is a reminder to deliver the right amount of care on schedule – it ties together Medicare payment rules and patient well-being.

Key Takeaways

• LUPA = Low Utilization Payment Adjustment. It triggers when a home health 30-day period has fewer skilled visits than the Medicare-set threshold.
• Under PDGM, thresholds vary. Each patient’s case-mix group determines a threshold (usually 2–6 visits). Under the old 60-day system, it was a flat “4 or fewer visits” rule.
• Below threshold means lower pay. A LUPA episode is reimbursed at the (much lower) per-visit rate, not the full case-mix rate. This can cut total payment dramatically.
• Know your case-mix factors. The patient’s diagnosis, admission source, functional status, and comorbidities all set the LUPA threshold. More complex patients generally have higher thresholds.
• Plan to avoid LUPAs. Efficient scheduling, accurate documentation, and prompt rescheduling of missed visits help agencies meet thresholds and protect revenue.

Understanding LUPA helps home health teams and families know why visit counts matter for Medicare reimbursement. By meeting the expected number of visits, agencies avoid payment cuts and help patients get the full care they need.
