Your back or neck surgery was denied because the plan says it did not get enough information

What your letter means

The plan says it could not decide, or said no, because records were missing, incomplete, unreadable or late. Letters often say "insufficient documentation", "information not received", "lack of clinical information" or "unable to determine medical necessity".

This is often the most fixable kind of denial: the facts may already be in your chart and simply did not reach the reviewer in a form that matches the rule.

For scale: in 2024, administrative reasons (which include missing information, duplicate and late claims) were 25% of the reasons HealthCare.gov insurers gave for denying in-network claims. That figure covers all kinds of care, not spine surgery alone. KFF, March 2026

What the plan's own rules say

• UnitedHealthcare, Blue Cross and Blue Shield of Texas, Cigna and Medicare Advantage each use their own published rules or a review company's guidelines, and your letter should name the one applied. If it does not, ask for it in writing: see asking for the claim file and criteria, and which kind of plan you have.
• A Medicare contractor's own words (Medicare billing article A53972 (Noridian, a Medicare contractor for other states)): the most common reason spinal fusion is denied is missing specific information about non-surgery treatment.

Your rights to the papers:

• A job-based or Marketplace plan must give you, free on request, copies of the documents relevant to your claim and any rule or criterion it relied on. 29 CFR 2560.503-1(h)(2)(iii), (g)(1)(v)(A)
• The denial must include the denial code and its meaning, and the plan must give you the diagnosis and treatment codes on request. 45 CFR 147.136(b)(2)(ii)(E)
• Your doctor's office must act on your request for your records within 30 days (one 30-day extension allowed, with a written reason) and may charge only a reasonable, cost-based fee. 45 CFR 164.524(b)(2), (c)(4)

Plans change their rules, and the one that counts is the rule in force when your surgery was requested. A job-based or Marketplace plan must give you a copy free (how to ask). 29 CFR 2560.503-1(g)(1)(v)(A), (h)(2)(iii)

What an appeal for this reason needs to contain

• The plan's own list of what was missing, taken from the denial letter.
• Each missing item, attached and labeled with the requirement it answers, with a one-page index on top.
• Your written request for the claim file and the criteria used, if the letter does not name them.
• A letter of medical necessity signed by your surgeon.
• Your signed appeal letter with the plan's reference number, and a request that the plan confirm it received every page.
• Also ask your surgeon's office whether they can send the missing records as a new request. That can be faster than an appeal; you can still file the appeal before your deadline.

Deadlines depend on the kind of plan

Your denial letter controls. It must tell you your deadline and where to send the appeal. For job-based and Marketplace plans the federal rule gives at least 180 days from the day you got the letter (29 CFR 2560.503-1(h)(3)(i)). Medicare Advantage gives 60 days (42 CFR 422.582(b)). Plans can give you more time, not less. The steps after a final "no" are set out in federal outside review, Texas outside review and which kind of plan you have.

What Denial Reply does

For a denial that says records or information were missing, Denial Reply reads your letter and records and prepares a packet for you to review and sign, free during our test. A person checks every packet, and nothing is sent without your separate signed permission. The full list is here.

What Denial Reply never does

Denial Reply never signs for you or your doctor, never changes a medical record, never tells you whether you have a legal claim and never promises a result. It is not a law firm. The full list is here.

Who this is for

This is for Texas adults, 18 or older, appealing their own back or neck surgery denial, a denial that says records or information were missing, under a job-based, Marketplace, Texas-regulated or Medicare Advantage plan. It is not for children, people outside Texas, Medicaid, traditional Medicare or decisions needed within 72 hours. See the full description.
