The Home Health Certification Chain: Who Signs What Before Medicare Pays

Home health certification requirements connect a patient’s homebound status and skilled-care needs to an encounter, a practitioner-approved plan and the agency’s Medicare claim. The referral starts the process. The assessment records what the patient needs. The certification puts an authorized practitioner’s judgment behind eligibility for payment. If you work in intake, nursing, therapy or billing, you may see the point where the patient’s actual condition stops matching what the paperwork says.

The chain crosses offices as well as job titles. A hospital may hold the encounter note, a community practitioner may oversee the patient, and the agency may hold the assessment, orders and visit records. We look for the break between those records. A signature at the end cannot supply the clinical facts missing at the beginning.

Who Signs What Before Medicare Pays?

A physician or allowed practitioner certifies that the patient is homebound, needs qualifying skilled care, has a plan of care that the practitioner establishes and reviews, remains under practitioner care, and has had a timely face-to-face encounter related to the home health need. The encounter professional and the agency’s assessing clinician have separate responsibilities.

Under the Centers for Medicare & Medicaid Services definition of an allowed practitioner, nurse practitioners, clinical nurse specialists and physician assistants can certify and recertify eligibility, order home health services and establish and review the plan. They must practice within the applicable state requirements.

A physician or an authorized non-physician practitioner performs the face-to-face encounter. A state-authorized certified nurse-midwife can perform that encounter, but cannot certify home health eligibility on that authority alone. A registered nurse performs the agency’s comprehensive assessment, with specified exceptions for therapy-only cases.

When the practitioner who cared for the patient in a hospital or post-acute facility certifies eligibility but will not follow the patient after discharge, the certification must identify the community physician or allowed practitioner who will. The discharge record explains the starting condition. The community practitioner takes responsibility for continuing oversight.

The agency submits its claim to the Medicare Administrative Contractor. Practitioners bill separately under Medicare Part B, using G0180 for certification and G0179 for recertification. Those services depend on Medicare-covered home health care supported by a complete certification and adequate eligibility documentation.

A practitioner’s financial relationship with the agency can also restrict certification authority. We examine who signed alongside the arrangements connecting that practitioner to the agency.

The Face-to-Face Encounter Must Explain the Need for Home Health

The face-to-face encounter must occur no more than 90 days before, or within 30 days after, the start of home health care and must relate to the primary reason the patient needs those services. The certifier documents the encounter date. The actual clinical note belongs in the medical records supporting eligibility.

The date and the clinical connection do different work. When a patient’s condition changes after an earlier visit, another encounter is needed if the change requires an examination to establish an effective treatment plan.

The supporting record must substantiate both homebound status and skilled need. The clinical picture matters more than a stock phrase pasted into a form.

Initial qualifying skilled care includes intermittent skilled nursing, physical therapy or speech-language pathology. Continuing occupational therapy can sustain eligibility after the initial qualifying need ends. Skilled maintenance care rests on the need for professional skill to maintain function or prevent deterioration. These are clinical judgments that the encounter note, assessment and plan need to support together.

The Encounter Rules Changed

The authority behind a signature depends on the service date. The permanent expansion allowing nurse practitioners, clinical nurse specialists and physician assistants to certify and order home health applied to services beginning March 1, 2020. The later home health final rule broadened which physicians can perform the encounter beginning January 1, 2026, beyond the former restriction to the certifying or discharging physician.

The general requirement for a separate face-to-face narrative ended for episodes beginning January 1, 2015. The encounter and the supporting medical record remained. A specific clinical narrative still applies when skilled nursing management and evaluation are needed to oversee otherwise unskilled care.

Who Is Not Able to Complete an OASIS Assessment?

Someone outside the authorized assessment roles cannot complete the comprehensive assessment. A registered nurse performs it, with specified therapy-only exceptions. An occupational therapist’s assessment authority does not make occupational therapy alone an initial qualifying service for Medicare home health.

The initial assessment visit is due within 48 hours of referral or return home, or on the ordered start date, while the comprehensive assessment is due no later than five calendar days after care starts. These are separate events from the practitioner’s encounter and certification.

What Is an OASIS Form for Home Health?

OASIS is the standardized assessment item set within the agency’s comprehensive assessment. It supplies information for payment grouping, quality reporting and measures of patient improvement. The Medicare claim and the eligibility certification remain separate documents with their own requirements.

That makes the original clinical assessment important beyond the bedside. Functional answers can affect payment grouping and measured improvement, while diagnoses on the claim supply other payment inputs. An altered assessment can therefore change the story told to both the payment system and the quality system.

The assessment version matters too. OASIS-E2 took effect April 1, 2026. When we examine a suspected alteration, we connect the clinician’s observation to the version completed, the later change and the submitted data. The question is who changed the account of the patient’s condition, and what that change did to the claim.

The Plan of Care Gives the Signature Its Meaning

The plan of care must specify patient-specific services, the responsible disciplines, and the frequency and duration of visits. Therapy plans must carry measurable treatment goals and a course of treatment consistent with the therapist’s assessment. The visits furnished must follow that plan.

The Centers for Medicare & Medicaid Services’ voluntary plan-of-care template, dated July 2018, shows how much sits behind the signature: diagnoses, functional limitations and measurable goals. The template also keeps orders and revisions in the plan.

Orders must be specific. For as-needed visits, the Centers for Medicare & Medicaid Services requires the medical signs and symptoms that would prompt a visit and a limit on the visits allowed before another order is necessary. An increase in frequency or an additional service needs a written or oral order before the increased or additional care is furnished.

Agency Notes Need Corroboration

Agency assessments and plans can support eligibility when incorporated into the certifier’s medical record, corroborated by other entries in the practitioner’s or discharging facility’s record, and signed and dated by the certifier. The information needs to fit the period of care and create a consistent clinical picture.

This is where a completed packet can conceal an empty handoff. The agency may have written the description, supplied the assessment and sent the plan for signature. The question is what in the practitioner’s or facility’s own record supports that account. We look for that connection, because repeating the same assertion in several places adds no independent clinical support.

Signatures Must Precede the Claim

The plan and certification must be signed and dated before the agency submits the claim for payment. Certification is obtained when the plan is established or as soon afterward as possible. The Centers for Medicare & Medicaid Services expressly rejects waiting until the certification period ends to obtain it. The 2026 rule also makes clear that certification cannot be completed after discharge.

Oral orders have their own sequence: authorized staff receive and document the order, and the physician or allowed practitioner countersigns and dates it before the agency bills for that care. The order date, the visit date and the signature date each tell part of the story.

An authorized covering practitioner can sign the plan or recertification while the original practitioner is absent. The agency must ensure that the covering practitioner was authorized to care for those patients. Electronic signatures likewise depend on authentication, a date and identification of the person who reviewed and approved the entry. The CMS certification manual requires safeguards against unauthorized access to those records.

Thirty-Day Payment and Sixty-Day Certification Review

Home health uses a 30-day payment period and a 60-day certification and plan-review cycle. The Patient-Driven Groupings Model introduced the shorter payment period on January 1, 2020. A certification period can include two payment periods.

Continuing care requires recertification at least every 60 days and plan review at least as often, with earlier review when the patient’s needs require it. The recertification assessment generally falls in the last five days of the preceding certification period. Another payment period does not supply a new clinical judgment by itself.

Recertification addresses the continuing homebound and skilled-care needs, the plan and practitioner oversight. The updated plan still specifies visit frequency and duration. The Benefit Policy Manual says the practitioner no longer has to provide a separate estimate of how much longer skilled services will be needed.

When the Certification Chain Is Altered

The most revealing evidence can be the difference between the original record and the version used to support payment. The signature, the clinical judgment and the decision to bill can each be changed by a different person.

Changing the Signature Date

In the Great Lakes Home Healthcare Specialists matter, the government’s complaint alleged that management directed an employee to alter physician signature dates. The complaint describes what allegedly happened to the original:

The Justice Department’s settlement announcement described a $450,000 settlement with the owner and businesses covering allegations that included altered signature dates, therapy that was never provided and unqualified social-work services. The signature’s presence was only part of the question. The government alleged that someone changed when it appeared to have been given.

Keeping the Patient After the Clinician Recommends Discharge

The whistleblowers’ complaint concerning Carter Healthcare’s Florida operations alleged pressure to retain patients and recertify care without medical need. It quoted an employee celebrating the result:

The complaint also alleged that patients were reassigned when therapists opposed continued care, with earlier treatment records withheld from replacement therapists to conceal discharge recommendations. In the Florida civil resolution, Carter Healthcare agreed to pay $6.925 million over allegations of unnecessary therapy and inaccurate assessments under the payment model then in effect.

We see the problem in that celebration: keeping a patient on the books had become the achievement. We connect the original therapist’s recommendation to the next certification. The clinical judgment can disappear while the billing continues.

A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers. If you are a healthcare worker who saw the patient’s condition rewritten for billing, we can build that connection with you.
