How to Get Medicare Certified as a Home Health Agency: CMS Form 855A, PECOS, and Accreditation
Medicare certification for a home health agency is one of the most complex regulatory processes in the healthcare industry. Unlike opening a physician practice or a clinic, home health certification involves parallel tracks — state licensure, federal enrollment, third-party accreditation, and a physical survey of your clinical operations — that must be coordinated precisely. Misunderstanding the sequence or timeline of any one step can add months to your launch. This guide walks you through every required step in order, with realistic timelines, common failure points, and the forms you need.

Step 1: Obtain Your State Home Health Agency License
Every state requires a separate home health agency license before you can operate — this is distinct from Medicare certification and must be obtained first. State licensure applications typically require: proof of entity formation (LLC or corporation), a clinical director (must be an RN with home health experience in most states), a business address, evidence of professional liability insurance, and in some states, a surety bond of $50,000–$100,000. Application processing times range from 30 days (Texas, Arizona) to 6 months (California, New York). Some states conduct a pre-survey inspection before issuing a license. Contact your state health department's home health licensing division immediately — many states have significant backlogs that are not advertised. Note that your clinical director (RN) must typically be employed or contracted before you submit the state application.
Step 2: Obtain Your NPI Type 2 and Business Enrollment
Your home health agency must obtain a National Provider Identifier (NPI) Type 2 — the organizational NPI — through the National Plan and Provider Enumeration System (NPPES) at nppes.cms.hhs.gov. This is free and takes 1–2 business days once submitted. You will need your organization's legal name, EIN (Employer Identification Number from the IRS), physical address, and taxonomy code for home health agencies (251G00000X for Medicare Home Health). The NPI Type 2 is required before you can submit CMS Form 855A. Your individual clinical staff members (RNs, PTs, OTs) should also have their own NPI Type 1 numbers — verify this for every clinician before credentialing them on your roster.
Step 3: Submit CMS Form 855A via PECOS
CMS Form 855A is the Medicare enrollment application for institutional providers including home health agencies. It is submitted through the Provider Enrollment, Chain, and Ownership System (PECOS) at pecos.cms.hhs.gov. The 855A requires your agency's NPI Type 2, state license, ownership information (every individual or entity owning 5%+ of the agency), clinical director's licensure information, and a signed certification. As of 2026, the Medicare Administrative Contractor (MAC) processing time for 855A applications runs 60–90 days after receipt of a complete application. Incomplete applications are the most common cause of delays — use the CMS 855A checklist and have a healthcare attorney review before submission. Upon approval, you will receive a CMS Provider Transaction Access Number (PTAN) and a Medicare billing number, which are required for billing but not sufficient alone — you still need to pass the CMS survey.
Step 4: Pursue CHAP or JCAHO Accreditation (Deemed Status)
CMS certifies home health agencies through one of two pathways: (1) a direct CMS survey conducted by the state survey agency, or (2) deemed status accreditation through a CMS-approved accrediting organization — currently CHAP (Community Health Accreditation Partner) or The Joint Commission (JCAHO). Deemed status accreditation is generally preferred because accrediting organizations can schedule surveys faster than state agencies in most regions and provide clearer preparation guidance. CHAP accreditation costs approximately $3,000–$6,000 for the initial survey and annual fees. JCAHO home health accreditation has similar costs. Both organizations conduct an on-site survey evaluating your clinical policies, staff credentials, patient record systems, supervisory structures, and emergency preparedness plans against CMS Conditions of Participation (42 CFR Part 484). You must have at least one Medicare patient admitted before the survey can occur — this is often called the 'clinical readiness' requirement. Plan your first admitted patient carefully.
Step 5: Medicaid Provider Enrollment
If you plan to bill Medicaid (including Medicaid waiver programs), you must separately enroll as a Medicaid provider through your state Medicaid agency. This is an entirely separate process from Medicare enrollment and is administered at the state level with no federal unified system. Most states require a completed provider enrollment application, proof of state licensure, tax identification information, and in some states a site visit or credentialing review. Medicaid enrollment for home health agencies takes 60–180 days depending on state. Some states require a surety bond specifically for Medicaid participation. Enroll in both Medicare and Medicaid simultaneously — run these tracks in parallel rather than sequentially to avoid adding months to your timeline.
Clinical Director and Staffing Requirements
CMS Conditions of Participation (42 CFR §484.105) require every Medicare-certified home health agency to have a qualified Administrator and a Clinical Manager who is a registered nurse. The RN Clinical Director must have at least one year of supervisory or administrative experience in home health or a related clinical field. Some states impose additional requirements — California requires the clinical supervisor to hold a Public Health Nurse (PHN) certificate. Before hiring your Clinical Director, verify that their license is active in your state with no encumbrances (use your state nursing board's license lookup). The Clinical Director's employment or contractor agreement should be documented and available for review during your accreditation survey. Additionally, every nurse aide employed or contracted by your agency must be listed on your state's Nurse Aide Registry.
Timeline Summary and Common Failure Points
Realistic timeline for a Medicare-certified home health agency from decision to first Medicare payment: Month 1–2: form legal entity, hire healthcare attorney, begin state licensure application, obtain NPI Type 2. Month 2–3: obtain state license (varies by state), apply for PECOS enrollment via Form 855A. Month 3–5: engage CHAP or JCAHO, begin building policy and procedure library, implement EMR and EVV systems, hire clinical staff. Month 5–6: admit first patient, schedule accreditation survey. Month 6–8: complete survey, receive Medicare certification, begin billing. Month 8–9: receive first Medicare payment (90-day billing cycle). The most common failure points are: (1) incomplete 855A applications causing MAC rejection, (2) missing or deficient clinical policies during survey, (3) insufficient patient census before survey, and (4) running out of operating capital before first Medicare payment. Every one of these is preventable with proper planning.

FREQUENTLY ASKED QUESTIONS
Do I need to be accredited by CHAP or JCAHO to get Medicare certified?
No — you can pursue direct CMS certification through your state survey agency without third-party accreditation. However, most healthcare attorneys and startup consultants recommend pursuing CHAP or JCAHO accreditation (deemed status pathway) because accrediting organizations typically schedule surveys faster, provide clearer preparation guidance, and result in fewer citation deficiencies than CMS direct surveys. The accreditation cost of $3,000–$6,000 is modest relative to the months it can save.
Can one person serve as both Administrator and Clinical Director?
CMS Conditions of Participation do not explicitly prohibit one person from holding both the Administrator and Clinical Manager roles, and in many small startup agencies an RN founder serves in both capacities. However, this creates significant workload demands and potential survey risk — surveyors will scrutinize whether clinical supervision functions are being adequately performed. As your agency grows beyond 10–15 concurrent patients, separating these roles becomes operationally necessary. Always confirm your state's specific requirements, as some states explicitly require separate individuals for these roles.
What is PECOS and why does it matter for home health billing?
PECOS (Provider Enrollment, Chain, and Ownership System) is CMS's online portal for Medicare provider enrollment. Your home health agency's PECOS record must be active and accurate before you can bill Medicare. When a physician orders home health services, their NPI must also be active in PECOS — if the ordering physician is not enrolled in PECOS, Medicare will deny your claims. This is one of the most common billing denials for new home health agencies: always verify that any physician ordering home health for your patients has an active PECOS record before submitting claims.
