Question 1

Does Medicare cover appendectomy?

Accepted Answer

Yes. Medicare covers laparoscopic appendectomy (CPT 44970) as an emergency procedure when medically necessary. Because appendectomy is almost always an urgent or emergent surgery, most cases are admitted inpatient and covered under Part A. The DRG 346 Medicare payment for simple appendectomy (without complications) is $9,237 in 2026 — this bundled payment covers the hospital stay, surgery, and nursing care. You pay the $1,736 Part A deductible.

Question 2

Is appendectomy covered as inpatient or outpatient under Medicare?

Accepted Answer

Most appendectomies require inpatient admission and are covered under Part A. Uncomplicated cases may occasionally be observed or discharged same-day, which would trigger Part B outpatient billing. If you are placed under observation status (rather than formal inpatient admission), your costs and Medicare rights differ significantly — observation status does not count toward the 3-day qualifying stay for SNF coverage. Always ask whether you are formally admitted as inpatient.

Question 3

What is the Medicare Part A deductible for appendectomy?

Accepted Answer

The 2026 Part A deductible is $1,736 per benefit period (roughly per hospitalization). This covers days 1–60 of the hospital stay. For most appendectomy patients, the hospital stay is 1–3 days, so the $1,736 deductible is the primary out-of-pocket cost under Part A. The surgeon bills separately under Part B (CPT 44970, approximately $326 nationally; your 20% share: $65). Total out-of-pocket without Medigap: approximately $1,800. With Medigap Plan G: $283.

Question 4

Why does this calculator show a different amount than Medicare.gov's cost estimate?

Accepted Answer

This calculator may show a higher number than Medicare.gov's "Patient Pays (average)" for several reasons: (1) Deductible timing — this calculator applies the $283 Part B annual deductible if it has not yet been met; Medicare.gov's average assumes many patients have already satisfied theirs. (2) Anesthesia — Medicare.gov's estimate covers the facility fee and surgeon only; anesthesia is billed separately and is included in this calculator. (3) Location adjustment — surgeon fees are adjusted by your region's Geographic Practice Cost Index (GPCI); in high-cost cities like Seattle or New York, surgeon fees run 30–50% above the national rate. Facility fees (HOPD and ASC) are nationally fixed by CMS and should match Medicare.gov exactly. (4) Patient mix — Medicare.gov's "Patient Pays" average includes Medigap enrollees who pay $0 coinsurance, which pulls the reported average below what uninsured Original Medicare patients typically pay.
