What Is Home Health Care
Home health care is skilled nursing, therapy, or medical services delivered in your home under a physician's order. Insurance covers these services only when they meet the payer's definition of medical necessity and are authorized in advance through prior authorization.
Unlike routine home care or custodial assistance (help with bathing, dressing, or meals), home health must involve skilled clinical judgment. Common covered services include wound care, IV therapy, physical therapy, occupational therapy, speech-language pathology, and skilled nursing assessment. Medicare covers home health under Part A when you meet homebound status, have a physician referral, and need daily skilled care. Private insurers apply stricter timelines and visit limits, typically authorizing 2 to 4 weeks initially before requiring recertification.
Insurance Coverage and Denials
Denials for home health care fall into three categories: lack of prior authorization, failure to meet medical necessity standards, or exceeding authorized visit limits.
- Prior Authorization Gaps: Many insurers require authorization before the first visit. If your provider submitted the request but you received no approval letter, your insurer may deny claims retroactively, even if care was delivered. Check your Explanation of Benefits (EOB) for the specific denial reason code.
- Medical Necessity Challenges: Insurers often deny home health by claiming the condition does not require skilled intervention or that you could receive equivalent care in an outpatient setting. They cite specific medical policy limitations, such as requiring documentation that daily skilled nursing is needed, not weekly oversight.
- Visit Limit Denials: Your authorization may cover 10 visits over 21 days. Claims beyond that threshold are denied unless your provider submits a recertification request with updated clinical notes showing ongoing medical necessity.
Appealing Home Health Denials
Home health denials typically proceed through two appeal levels before external review becomes available.
- Internal Appeal (Level 1): Submit within 30 to 180 days (check your plan documents) with clinical evidence: physician notes explaining why home-based care is medically necessary, skilled nursing assessments, progress notes, and any improvement or decline documentation. Reference your state's insurance code if applicable. For example, New York Insurance Law Article 49 requires insurers to cover medically necessary home health when ordered by a physician.
- Internal Appeal (Level 2): If denied again, request escalation to a medical director review. Include a physician letter stating why outpatient care is unsafe or impractical for this patient's condition. Specify comorbidities, mobility limitations, or infection control requirements that necessitate home delivery.
- External Appeal: After exhausting internal appeals, request an independent external review with your state's insurance commissioner's office. Most states require the insurer to comply within 30 to 45 days. External reviewers evaluate whether the denial violated the insurer's medical policy or state regulations.
Reading Your EOB for Home Health Claims
Your Explanation of Benefits will show each home health claim separately, grouped by provider and date of service. Look for these fields: the service code (99500 series for skilled nursing, 97161-97168 for therapy evaluations), the number of units billed (typically one unit per visit), the amount allowed by the plan, your cost-sharing responsibility, and the denial reason if applicable. The denial code number (such as "Care not authorized" or "Not medically necessary per plan guidelines") determines your appeal strategy.
Common Questions
- If my doctor ordered home health but my insurer denied it, can they do that? Yes. Insurance companies have the legal right to apply their own medical policy standards, which may differ from your physician's clinical judgment. A physician order is necessary but not sufficient for coverage. This is why prior authorization before care starts is critical. If the authorization was denied, your appeal must demonstrate that the insurer's policy contradicts standard medical practice or violates state law.
- How long can home health be covered? Coverage duration depends on your plan and diagnosis. Medicare covers up to 60 days per episode (with potential extension), while private insurers often limit initial authorization to 10 to 15 visits, requiring physician recertification with updated clinical justification for continued services. Check your authorization letter for the specific visit count and expiration date.
- My provider says the claim was denied because I am not homebound. What does that mean? Homebound status means you cannot leave home safely without considerable/taxing effort due to illness, injury, or disability. Medicare strictly enforces this rule. If your insurer claims you are not homebound, ask for the specific policy definition they used and challenge it with evidence: physician documentation of mobility limitations, fall risk, cognitive impairment, or medical contraindications to travel. Some states require this standard; others do not, so check your state insurance code.
