AHIP PHIAS common mistakes
AHIP PHIAS · Understand the traps and how to avoid them.
Treating the terms 'Medicare Advantage' and 'Medicare Supplement (Medigap)' as interchangeable when answering questions about cost-sharing, provider networks, and enrollment periods.
Both are private-plan options layered on Original Medicare, so candidates lump them together and apply Medigap rules (any provider who accepts Medicare, no networks) to MA questions or vice versa.
What to do instead
Build a two-column comparison card: MA = network/HMO-PPO structures, may include Part D, annual enrollment with lock-in periods; Medigap = standardized lettered plans, works alongside Original Medicare, no networks, guaranteed-issue windows tied to initial enrollment. Drill by restating which product the stem actually describes before answering.
Confusing Medicare Part A, Part B, Part C, and Part D coverage boundaries-e.g., attributing outpatient prescription drugs to Part B or skilled nursing facility stays to Part B.
The lettered parts overlap in real claims scenarios and candidates memorize labels without mapping each to a benefit category (inpatient hospital, outpatient/medical, MA alternative, drugs).
What to do instead
Memorize a one-line benefit map for each part and test yourself with mixed scenarios ('which part pays?') rather than isolated definitions. Include the Part A/B distinction for SNF (Part A covers post-inpatient SNF; Part B covers outpatient therapy).
Misapplying Medicare Advantage enrollment and disenrollment timing-assuming a member can switch plans any month or ignoring the difference between the Initial Enrollment Period, Annual Enrollment Period, and MA Open Enrollment Period.
Candidates generalize from commercial insurance 'open enrollment' habits and overlook the constrained windows and lock-in rules specific to MA.
What to do instead
Create a timeline diagram with each window's dates, who qualifies, and what changes are permitted. Practice stems that hinge on 'when can this member change?' and verify the specific election period before selecting an answer.
Selecting an answer that describes a network model (HMO, PPO, POS, EPO) using the wrong defining feature-e.g., saying an HMO allows out-of-network care at higher cost, or that a PPO requires a PCP referral.
The models share features (copays, networks, referrals) and candidates rely on vague impressions rather than the defining structural rule of each.
What to do instead
For each model, write the single defining rule: HMO = in-network only except emergencies, PCP gatekeeping; PPO = out-of-network allowed with reduced benefits, no referral; POS = hybrid with gatekeeping but out-of-network option; EPO = network only, no referral required. Answer by matching the stem to the defining rule, not the peripheral features.
Conflating utilization management tools-preauthorization, concurrent review, case management, and retrospective review-when a scenario asks which function applies.
These terms are used loosely in practice, and candidates answer based on the setting (hospital, clinic) rather than the timing and purpose of each tool.
What to do instead
Anchor each tool to its timing: prospective (preauthorization before service), concurrent (during the stay), retrospective (after claims), and case management (ongoing coordination for high-cost members). Classify each practice question by timing first, then match the tool.
Mixing up HSA, HRA, and FSA rules-contribution limits, rollover/portability, and whether the account is tied to a high-deductible health plan.
All three are tax-advantaged accounts attached to consumer-directed plans, so candidates treat them as variants of one product and lose track of which is portable and which requires an HDHP.
What to do instead
Make a three-row table with columns: HDHP required?, who funds it, portable when leaving job?, rollover rules. Memorize that the HSA is individually owned and portable and requires an HDHP, while HRAs are employer-funded and generally not portable. Answer by checking the account type against the stem's facts.
Assuming consumer-directed health plans (CDHPs) always reduce costs for the member, ignoring the deductible-to-out-of-pocket-maximum relationship and first-dollar coverage differences.
Marketing language around CDHPs emphasizes lower premiums, and candidates overlook that higher deductibles shift cost to the member until the OOP maximum is reached.
What to do instead
For any CDHP scenario, calculate or compare the deductible, coinsurance, and OOP maximum before judging cost. Practice questions that ask 'which plan costs the member more for a given claim' by walking through the cost-sharing sequence.
Confusing short-term disability and long-term disability definitions-elimination periods, benefit durations, and the definition of disability (own occupation vs. any occupation).
Both are income-replacement products and candidates apply the wrong waiting period or occupation standard to the stem's facts.
What to do instead
Memorize the structural contrast: STD = short elimination period, benefits typically up to ~26 weeks, often own-occupation; LTD = longer elimination period, extended duration, frequently any-occupation after an initial period. Read the stem for the waiting period and duration clues before selecting.
Treating long-term care insurance triggers and benefit mechanics incorrectly-e.g., assuming benefits begin at diagnosis or that LTC covers only nursing-home care.
Candidates rely on general impressions of LTC and miss the benefit-trigger (inability to perform a set number of activities of daily living or cognitive impairment), the elimination period, and the range of covered settings.
What to do instead
Memorize the standard trigger (typically inability to perform 2 of 6 ADLs for at least 90 days, or severe cognitive impairment) and the covered settings (home care, assisted living, nursing home). Practice identifying the trigger and benefit period in scenario stems.
Overlooking worksite benefit tax treatment and coordination-treating employer-paid and employee-paid premiums the same, or ignoring how group benefits coordinate with other coverage.
Worksite benefits sit at the intersection of group insurance and tax rules, and candidates answer on product features without checking who pays and how benefits coordinate.
What to do instead
For each worksite question, first identify who pays the premium (employer vs. employee) and whether the benefit is taxable, then check for coordination-of-benefits or non-duplication provisions. Build a quick checklist to run before answering.
