Please note, the Local Coverage Determinations, L33622 and L37635, the Plan used in their decision to deny services are not binding in this case. The rules do not have Medicare Part B jurisdiction where the services were provided.
The rules say that plans must pay for a medical service or item if regular Medicare would pay for it in this case. You can find this rule at 42 Code of Federal Regulations (CFR) Section 422.101.
The rules say that peripheral nerve blocks will be considered medically reasonable and necessary for conditions such as the following diagnostic and therapeutic purposes:
1. When the patient's pain appears to be due to a classic mononeuritis but the neuro-diagnostic studies have failed to provide a structural explanation, selective peripheral nerve blockade can usually clarify the situation.
2. When peripheral nerve injuries/entrapment or other extremity trauma leads to complex regional pain syndrome.
3. When selective peripheral nerve blockade is used diagnostically in those cases in which the clinical picture is unclear.
4. When an occipital nerve block is used to confirm the clinical impression of the presence of occipital neuralgia. Chronic headache/occipital neuralgia can result from chronic spasm of the neck muscles as the result of either myofascial syndrome or underlying cervical spinal disease. It may be unilateral or bilateral, constant or intermittent. Nerve injury secondary to a blow to the back of the head or trauma to the nerve from a scalp laceration can also cause this condition. Most commonly it is caused by an entrapment of the occipital nerve in its course from its origin from the C2 nerve root to its entrance into the scalp through the mid portion of the superior nuchal line. Blockage of the occipital nerve can confirm the clinical impression of occipital neuralgia particularly if the clinical picture is not entirely typical. If only temporary relief of symptoms is obtained, neurolysis of the greater occipital nerve may be considered via multiple techniques including radiofrequency and cryoanalgesia. In addition, the lesser and third occipital nerves can be involved in the pathology of headaches, and can be treated in a similar manner.
5. When the suprascapular nerve block is used to confirm the diagnosis of suspected entrapment of the nerve. Entrapment of the suprascapular nerve as it passes through the suprascapular notch can produce a syndrome of pain within the shoulder with weakness of supraspinatus and infraspinatus muscles. When the history and examination point to the diagnosis, a suprascapular nerve block leading to relief of pain can confirm it. This may be followed by injection of depository steroids that sometime provide lasting relief.
6. When the trigeminal nerve is blocked centrally at the trigeminal ganglion, along one of the three divisions or at one of the many peripheral terminal branches (i.e., supraorbital nerve).
7. Nerve blocks as preemptive analgesia
A. When a single injection peripheral nerve block provides post-surgical pain control
1. during the transition to oral analgesics
2. in those procedures which cause severe pain normally uncontrolled by oral analgesics
3. in cases otherwise requiring control with intravenous or parenteral narcotics.
4. in cases where the patient cannot tolerate treatment with narcotics due to allergy or side effects, etc.
B. When a continuous peripheral nerve block provides the same as above, and furthermore may provide extended (i.e., one to five or more days) relief as a result of chronic administration of anesthetic.
As published in the Centers for Medicare and Medicaid Services, Internet Only Manual, Publication 100-08, Medicare Program Integrity Manual, Chapter 13, Section 13.5.4, an item or service may be covered by a contractor LCD if it is reasonable and necessary under the Social Security Act Section 1862 (a)(1)(A). Contractors shall determine and describe the circumstances under which the item or service is considered reasonable and necessary. You can find this rule in the Local Coverage Determination for Peripheral Nerve Blocks, L33933 (eff 01/08/19).

The Plan contract says that the Plan covers items and services in accordance with Medicare rules.
