CMS-485 Home Health Certification and Plan of Care

Medicare home health agencies use this plan-of-care layout to put a patient's orders, diagnoses, functional limits and goals for a certification period in front of the certifying practitioner. The agency drafts it; the physician or allowed practitioner reviews the orders and signs the statement that the patient is homebound and needs intermittent skilled care. The agency keeps the signed copy, which must be in place before it bills.

Who completes it

The home health agency fills in items 1 to 25 from its assessment and the referral, and a nurse signs item 23 when care starts on verbal orders. The certifying physician or allowed practitioner (nurse practitioner, clinical nurse specialist or physician assistant) reviews the orders and signs and dates item 27.

How to fill it in

Items 1-9: Patient and provider identification

The agency enters the patient's claim number, start of care date, certification period (from and to), medical record number, provider number, patient name and address, agency name and contact details, date of birth and sex. Check that the certification period matches the dates you are certifying; a certification may cover less than 60 days but never more.

Items 10-13: Medications, principal diagnosis, surgical procedure and other pertinent diagnoses

Item 10 lists each medication with dose, frequency and route, flagged (N)ew or (C)hanged. Items 11 to 13 carry the principal diagnosis, any surgical procedure and other pertinent diagnoses, each with a date; the printed labels still say ICD-9-CM. Compare the medication list with your own records, because signing the plan authorizes the orders on it.

Items 14-17: DME and supplies, safety measures, nutritional requirements, allergies

These items list the equipment and supplies the patient needs, safety measures, nutritional requirements and allergies. The agency drafts them from its comprehensive assessment of the patient. Medicare requires the plan to specify the services needed to meet the patient-specific needs that assessment identified, so confirm these entries reflect the patient you saw.

Items 18-20: Functional limitations, activities permitted, mental status, prognosis

Item 18.A checks functional limitations such as amputation, incontinence, contracture, hearing, paralysis, endurance, ambulation, speech, legal blindness or dyspnea with minimal exertion. Item 18.B records activities permitted, from complete bedrest to no restrictions, including crutches, cane, wheelchair or walker. Item 19 marks mental status and item 20 the prognosis, from poor to excellent. Together they support the homebound and skilled-need statements you certify.

Item 21: Orders for discipline and treatments (specify amount/frequency/duration)

Orders must name each discipline and the type of service, with frequency and duration, for example skilled nursing 3 times a week for 4 weeks for wound evaluation and dressing changes. A range of visits is allowed, and the upper limit counts as the ordered frequency. 'As needed' or PRN orders must describe the signs and symptoms that would prompt a visit and cap the number of such visits.

Item 22: Goals/rehabilitation potential/discharge plans

Enter patient-specific goals, rehabilitation potential and discharge plans. When therapy is ordered, Medicare requires measurable treatment goals tied to the patient's illness or injury and resulting impairments, the expected duration of therapy, and a course of treatment consistent with the qualified therapist's assessment, set by the practitioner after any needed consultation with the therapist.

Items 23-25: Nurse's signature and date of verbal SOC, physician's name and address, date HHA received signed POT

When care starts on a verbal order, the nurse signs and dates item 23. Item 24 identifies the certifying practitioner by name and address, and the agency records in item 25 the date it received the signed plan of treatment. If a hospital practitioner certifies but will not follow the patient after discharge, the community practitioner who will must be identified.

Items 26-28: Certification statement, signature and warning

Item 26 is the certification that the patient is confined to the home, needs intermittent skilled nursing, physical therapy or speech therapy or continues to need occupational therapy, is under your care, and that you authorized the plan and will review it periodically. Sign and date item 27. Item 28 warns that misrepresenting or concealing information required for payment of federal funds may bring a fine, imprisonment or civil penalty.

Common mistakes

  • Signing after the agency has billed; the plan of care and certification must be signed and dated before the claim for each period is submitted.
  • Orders with no frequency or duration, or PRN orders that give no triggering signs and symptoms and no limit on the number of visits.
  • No face-to-face encounter note showing it occurred within the timeframe, related to the primary reason for home care, and was done by an allowed practitioner.
  • Relying on the signed plan alone; eligibility is judged on the certifying practitioner's or facility's records, which must support homebound status and skilled need.
  • Omitting the brief narrative clinical justification required when the patient's only skilled need is management and evaluation of the care plan.
  • Waiting until the end of the 60-day period to sign; CMS says certification should be completed when the plan is established or as soon as possible afterward.

Submitting and payment

How to submit it
Return the signed plan to the home health agency, which records the date received in item 25, keeps it and produces it on request for Medicare review; faxed and properly authenticated electronic signatures are accepted. It must be signed and dated before the agency submits the final claim for each 30-day period.
Who pays
Medicare Part B pays the certifying practitioner separately under the Physician Fee Schedule with HCPCS G0180 for certification and G0179 for recertification, but only when the home health claim itself is covered.

Good to know

  • Medicare does not require the CMS-485 layout itself. Certification statements can appear in other forms or formats as long as every required content element is present.
  • The printed form dates from February 1994 and still labels diagnosis items 11 to 13 as ICD-9-CM. It is no longer on the CMS forms list; CMS hosts it as a Program Integrity Manual exhibit.
  • The plan must be reviewed and signed at least every 60 days. A recertification period starts on day 61, and Medicare sets no limit on continuous 60-day recertifications.
  • A face-to-face encounter related to the primary reason for home care must occur no more than 90 days before or 30 days after the start of care, and the certifier documents its date.

Frequently asked questions

Can a nurse practitioner sign the CMS-485?

Yes. Medicare lets allowed practitioners, meaning nurse practitioners, clinical nurse specialists and physician assistants, certify and recertify home health eligibility, order services, and establish and review the plan of care, just as physicians can. They must practice within their state's law. The 'Attending Physician's Signature' label in item 27 predates this change.

How often does the CMS-485 need to be signed?

Each certification period covers up to 60 days. The plan of care must be reviewed and signed by the practitioner who established it at least every 60 days, with each review dated. Any change to the plan, and any new service or increased frequency during the period, needs a written or verbal order before it is provided.

Can the agency start care before the physician signs the CMS-485?

Yes, on a verbal order. A registered nurse or qualified therapist records the order and signs and dates it with the date received. The physician or allowed practitioner must then countersign and date the verbal orders, and sign the plan of care, before the agency bills the final claim for the period.

Does the face-to-face encounter go on the CMS-485?

The 1994 form has no field for it, but the certification must cover it: the certifier attests that a related face-to-face encounter happened within 90 days before or 30 days after the start of care and documents the encounter date. The clinical note of that encounter must be in the certifying practitioner's or the discharging facility's record.
