The American Medical Association (AMA) Current Procedural Terminology (CPT) codes and Healthcare Common Procedure Coding System (HCPCS) codes listed, are provided for informational purposes only. The codes reflect our interpretation of CPT/HCPCS coding requirements based upon AMA guidelines published annually. CPT/HCPCS codes are provided only as guidance to assist clients with billing. Baylor Genetics strongly recommends that clients confirm CPT/HCPCS codes with their Medicare Administrative Contractor (MAC) or other payer being billed, as requirements may differ. CPT coding is the sole responsibility of the billing party. Baylor Genetics assumes no responsibility for billing errors due to reliance on the CPT codes listed. Please direct any questions regarding CPT coding to the payer being billed.

Retinitis Pigmentosa + RPGR orf15 by Massively Parallel Sequencing (BCM-MitomeNGS^SM)
Test Information:	Confirmation of Clinical Diagnosis, Carrier testing
Test Details
Test Code:	2190
Special Notes:	66 genes involved in Retinitis pigmentosa (RP) are analyzed by the newly developed and clinically validated approach of Massively Parallel Sequencing (MPS) using Next Generation sequence technology. These genes are tabulated below and sequencing of subsets of the MitomeNGS panel may be ordered using the individual test codes listed. All exons of these 66 genes are examined by NGS. Exonic variants and intronic variants within 20bp of the exon/intron boundary will be reported. This massively parallel sequence analysis (BCM-MitomeNGS^SM) will not detect genomic structural rearrangements (eg. deletions, duplications, and inversions), large insertion mutations (e.g. ALU mediated insertion), and mutations within the promoter or deep intronic regions. Mutations and novel variants are confirmed by Sanger sequencing. Sequence analysis for each of the 66 genes responsible for RP by Massively Parallel Sequencing (BCM-MitomeNGS^SM) can also be ordered separately: ABCA4 (#6603), ABHD12 (#2410) , AIPL1 (#2430), BEST1 (#2920), C2orf71 (#2960), C8orf37 (#2420), CA4 (#2760), CDHR1 (#2385), CEP290 (#2415), CERKL (#2380), CLRN1 (#6660), CNGA1 (#2945), CNGB1 (#2940), CRB1 (#2845), CRX (#2950), DHDDS (#2965), EYS (#2970), FAM161A (#2990), FLVCR1 (#2485), FSCN2 (#2765), GUCA1B (#2775), GUCY2D (#2435), IDH3B (#2975), IMPDH1 (#2785), IMPG2 (#2450), KLHL7 (#2780), LCA5 (#2390), LRAT (#2835), MAK (#2495), MERTK (#2980), MFRP (#2405), NR2E3 (#2905), NRL (#2900), PDE6A (#2985), PDE6B (#2455), PDE6G (#2995), PRCD (#2465), PRKCG (#2895), PROM1 (#2395), PRPF3 (#2805), PRPF31 (#2795), PRPF6 (#2790), PRPF8 (#2800), PRPH2 (#2935), RBP3 (#2460), RD3 (#2830), RDH12 (#2955), RGR (#2475), RHO(OPN2) (#2915), RLBP1 (#2470), ROM1 (#2810), RP1 (#2910), RP2 (#2445), RP9 (#2820), RPE65 (#2930), RPGR (#2355), RPGRIP1 (#2350), SAG (#2480), SEMA4A (#2925), SNRNP200 (#2815), SPATA7 (#2850), TOPORS (#2890), TTC8 (#2400), TULP1 (#2840), USH2A (#6650), ZNF513 (#2490). RP panel also contains genes where mutation can cause Leber Congenital Amaurosis (AIPL1, CEP290, CRB1, CRX, GUCY2D, LCA5, LRAT, RD3, RDH12, RPE65, RPGRIP1, SPATA7, and TULP1).
