Skilled Need

Under the Medicare Benefit Policy Manual, Chapter 7, a service is skilled because of what it requires, not who happens to perform it. Recognized skilled nursing categories include observation and assessment of a changing or unstable condition, management and evaluation of a patient care plan, teaching and training the patient or caregiver, and direct hands-on care such as complex wound care, catheter management, and medication administration that requires nursing judgment. Therapy is skilled when the patient's condition requires the specialized judgment of a qualified therapist to design and adjust the program. A task a layperson could safely perform after instruction, like a routine dressing change on a healed wound, is not skilled even if a nurse does it.

When eligibility rests on skilled nursing, the need must be intermittent: skilled nursing needed or given on fewer than 7 days each week, or less than 8 hours each day, for periods of 21 days or less, with extensions possible in exceptional circumstances where the need for daily care is finite and predictable, such as a defined course of daily wound care. Patients needing full-time or indefinite daily nursing do not qualify under the home health benefit. Therapy-based eligibility carries no intermittent test, but visit frequencies must still be reasonable and necessary for the condition. Occupational therapy alone cannot establish initial eligibility, but once eligibility is established, a continuing OT need can sustain it.

Coverage does not depend on the patient's potential to improve. Following the Jimmo v. Sebelius settlement, CMS clarified that skilled care is covered when it is needed to maintain the patient's condition or to prevent or slow decline, so long as the skill of a nurse or therapist is required to deliver it safely and effectively. This matters for chronic, progressive, and neurological conditions: a stable diagnosis does not end coverage if the patient still needs skilled observation, program management, or maintenance therapy that only a professional can provide. The documentation burden shifts accordingly, from showing progress to showing why professional skill remains necessary.

Skilled need denials usually come from notes that record tasks instead of judgment. Habits that hold up in Additional Documentation Requests and Targeted Probe and Educate reviews:

• State why the service requires a nurse or therapist for this patient now, not just what was done
• Tie observation and assessment to concrete instability: changed medications, abnormal findings, physician contacts
• For teaching, document what was taught, to whom, the learner's progress, and why teaching continues
• For maintenance care, document why unskilled caregivers cannot safely carry the program
• Reconcile the documented need with ordered visit frequencies each period

Generic phrases like continue to monitor invite denial; specific clinical reasoning prevents it.
